Blockchain expertise that came with clear explanations, not just technical jargon

Hyun-Su Lim / Director of Platform - Hanam Tech Solutions
Verified
Feb 02, 2026

Project summary: A previous engagement had delivered something that worked in staging and struggled in production. We approached this project with greater rigour in vendor selection as a result.

The integration layer was the part of the project I was most concerned about going in. Our system landscape is complex, several of the upstream APIs we relied on were poorly documented, and two third-party vendors had a history of unpredictable response times on integration questions. This team managed all of that. They documented what the upstream vendors could not, built resilience into the integration architecture where the upstream behaviour was unreliable, and delivered a solution that works as specified in production. I could not have asked for more.

PROS

Commercially transparent throughout — no hidden assumptions, no bill shock at the end, change requests that were fair and clearly explained rather than used as a margin-recovery mechanism

CONS

Pipeline availability for kickoff required a few weeks of lead time — in hindsight that selection pressure means you are working with a team that is in demand for the right reasons

Questions & Answers

Please describe your company, your role, and the industry you operate in.
Hanam Tech Solutions operates in the Mining & Metals sector with headquarters in Incheon, South Korea. In my role as Director of Platform I am accountable for the full technology agenda — infrastructure, product, and vendor relationships. We are a commercially driven organisation and every technology decision is evaluated against a clear business case before it is approved.
What specific problem or business challenge led you to hire this company?
Our platform had been maintained by a previous vendor for three years and the accumulated technical debt had reached a point where delivery velocity had dropped to a fraction of what it should have been. We needed fresh engineering expertise and a structured plan to address the underlying issues.
What services did the company provide for your project?
The core engagement was Blockchain Development delivery, though their scope expanded to include technical consultancy during discovery that materially improved our requirements. They also took ownership of the third-party integration workstream that had been a coordination challenge in previous projects, removing that complexity from our internal team entirely.
Why did you choose this company over other providers you considered?
We ran a structured shortlisting process across five vendors. The technical evaluation eliminated two immediately. Of the remaining three, this team's proposal was differentiated by the specificity of their Blockchain Development approach and the evidence base they provided — reference projects in Mining & Metals contexts, not generic case studies. The reference calls confirmed a track record that the proposal had described accurately.
How clearly did the company understand your requirements and business goals?
Comprehensively. The discovery phase they ran was more thorough than anything we had experienced with previous vendors. They challenged requirements that were vague or contradictory, proposed alternatives where our initial thinking was limiting, and produced a functional specification that our internal stakeholders agreed was the clearest articulation of the product they had seen written down.
How was your overall experience with their communication and project management?
Professional and efficient. The project manager maintained a clear view of the critical path at all times and communicated changes to it transparently. The one significant scope adjustment we made mid-project was handled through a clean change request process — fairly priced, clearly documented, and absorbed without disrupting the overall timeline.
Did the company deliver the project on time and within your expected budget?
Yes to both. There was a single sprint where a dependency on a third-party API introduced a one-week delay. The team identified it three weeks in advance, presented two mitigation options, and we agreed on an approach that recovered the schedule within the same sprint cycle. That level of foresight is what separates good project management from reactive problem management.
What tangible results or business impact have you seen since the project was completed?
We went live four months ago. User adoption exceeded the target we had set by 23 percent in the first month. Support ticket volume has dropped measurably. The features we had deferred because the previous architecture made them prohibitively expensive to build are now in development. The platform they built has opened our roadmap.
What did you like most about working with this company?
The post-launch behaviour. Some vendors consider go-live to be the end of their professional obligation. This team treated it as the transition to a different kind of engagement. The hypercare period was substantive, the documentation was thorough and genuinely useful, and they checked in proactively at the thirty-day and ninety-day marks to review production metrics with us.
Would you recommend this company to others, and would you work with them again?
Unreservedly. We are in active scoping conversations for a second engagement and I expect this to develop into a multi-year partnership. For any organisation in the Mining & Metals sector looking for Blockchain Development expertise combined with genuine delivery discipline, I would put this team at the top of the evaluation list.

Technically rigorous, commercially grounded, and a genuine pleasure to work with

Project summary: Grid modernisation funding required us to demonstrate demand-response capability. The machine learning models existed on paper; we needed an engineering partner to build and productionise them.

The project brief was ambitious and we had received proposals ranging from two to five times our eventual budget from other vendors. This team came back with a proposal that was commercially realistic and technically credible — and then delivered against it. That alignment between proposal and outcome is not something I take for granted. I have been on the other side of it enough times to know it requires both honesty in the sales process and discipline in delivery. We experienced both.

PROS

Collaborative culture that made the team feel like a genuine extension of our organisation, strong asynchronous communication across time zones, zero-drama handling of the inevitable mid-project changes

CONS

Their discovery process is more rigorous than we were accustomed to and required more preparation from our side than we had initially allocated — but the quality of what followed justified every hour of it

Questions & Answers

Please describe your company, your role, and the industry you operate in.
I lead technology at Pacific Rim Commerce Group, a growth-stage Energy & Utilities business based in Perth, Australia. As GM of Technology my remit spans product engineering, platform operations, and strategic vendor partnerships. We had reached an inflection point where our internal capacity was not sufficient to execute our roadmap at the pace our market required.
What specific problem or business challenge led you to hire this company?
The immediate problem was that our Low-Code / No-Code Development capability had become the bottleneck limiting our ability to grow. Every feature request, every new client requirement, every internal initiative was delayed by a platform that had been extended beyond its original design. We needed a rebuild, not a patch.
What services did the company provide for your project?
The core engagement was Low-Code / No-Code Development delivery, though their scope expanded to include technical consultancy during discovery that materially improved our requirements. They also took ownership of the third-party integration workstream that had been a coordination challenge in previous projects, removing that complexity from our internal team entirely.
Why did you choose this company over other providers you considered?
A trusted peer in the Energy & Utilities sector had used them for a comparable Low-Code / No-Code Development engagement and their recommendation was unequivocal. Our own due diligence confirmed the pattern they described. The combination of domain knowledge, Low-Code / No-Code Development depth, and demonstrated delivery discipline was the deciding factor.
How clearly did the company understand your requirements and business goals?
Extremely well, in part because they had relevant Energy & Utilities experience that reduced the context-setting overhead significantly. They understood the domain vocabulary, asked the right questions, and translated business requirements into technical specifications with a fidelity that meant the development phase had very few clarification cycles.
How was your overall experience with their communication and project management?
Professional and efficient. The project manager maintained a clear view of the critical path at all times and communicated changes to it transparently. The one significant scope adjustment we made mid-project was handled through a clean change request process — fairly priced, clearly documented, and absorbed without disrupting the overall timeline.
Did the company deliver the project on time and within your expected budget?
Yes. I had privately built a contingency expectation into my planning given the project complexity and the number of integrations involved. None of that contingency was needed. The delivery landed on the agreed date and the final invoice matched the approved budget to within a fraction of a percent. That outcome is rarer than the industry acknowledges.
What tangible results or business impact have you seen since the project was completed?
The ROI case we presented to our board was conservative by design. Current performance against the financial model suggests we will hit the projected payback point in under twelve months against an eighteen-month target. The operational efficiency gains in particular have exceeded the model, in part because the quality of the data the new platform generates supports decisions that the previous system could not.
What did you like most about working with this company?
Their instinct for keeping the business objective visible throughout technical decision-making. I have worked with technically excellent teams who lose the strategic thread as complexity increases. This team maintained a clear connection between every architectural choice and the outcome we had agreed to achieve. That orientation made the trade-off conversations significantly easier.
Would you recommend this company to others, and would you work with them again?
Unreservedly. We are in active scoping conversations for a second engagement and I expect this to develop into a multi-year partnership. For any organisation in the Energy & Utilities sector looking for Low-Code / No-Code Development expertise combined with genuine delivery discipline, I would put this team at the top of the evaluation list.

Purpose-built software that made our competitors' off-the-shelf tools look obsolete

Takashi Morimoto / Director of IT Strategy - Sakura Digital KK

Jan 07, 2026

Project summary: Matter management had become a significant overhead for our fee earners. Every hour spent on administration was an hour not spent on billable advisory work — the business case was straightforward.

The thing that retrospectively seems most significant is how little drama there was. Complex technology projects tend to accumulate incidents, escalations, and tense conversations. This one did not. Problems were surfaced before they became incidents. Scope changes were handled with process rather than conflict. Risks were managed rather than avoided. That level of maturity is rare in my experience and it made the delivery feel almost effortless from our side, which I know it was not from theirs.

PROS

Production system that has performed as specified since go-live without remediation work, documentation thorough enough to support internal maintenance, knowledge transfer that left our team genuinely capable

CONS

Time zone coordination required some deliberate overlap management from both sides in the first couple of sprints, after which we had an efficient async rhythm that worked for the whole project

Questions & Answers

Please describe your company, your role, and the industry you operate in.
Sakura Digital KK operates in the Legal Services sector with headquarters in Tokyo, Japan. In my role as Director of IT Strategy I am accountable for the full technology agenda — infrastructure, product, and vendor relationships. We are a commercially driven organisation and every technology decision is evaluated against a clear business case before it is approved.
What specific problem or business challenge led you to hire this company?
We had a defined product vision for our next phase of growth in the Legal Services market but lacked the engineering depth internally to execute it. The Software Development requirements in particular required specialist experience that we could not realistically recruit for on the timeline our business plan required.
What services did the company provide for your project?
The core engagement was Software Development delivery, though their scope expanded to include technical consultancy during discovery that materially improved our requirements. They also took ownership of the third-party integration workstream that had been a coordination challenge in previous projects, removing that complexity from our internal team entirely.
Why did you choose this company over other providers you considered?
We ran a structured shortlisting process across five vendors. The technical evaluation eliminated two immediately.

They challenged requirements that were vague or contradictory, proposed alternatives where our initial thinking was limiting, and produced a functional specification that our internal stakeholders agreed was the clearest articulation of the product they had seen written down.
How was your overall experience with their communication and project management?
The project management framework was the most structured I have experienced with an external vendor. Sprint planning was tight, acceptance criteria were specific, retrospectives were honest and acted on. The project manager treated the shared backlog as a live document and the risk register as an operational tool rather than a compliance artefact. I never had to ask for a status update.
Did the company deliver the project on time and within your expected budget?
Yes to both. There was a single sprint where a dependency on a third-party API introduced a one-week delay. The team identified it three weeks in advance, presented two mitigation options, and we agreed on an approach that recovered the schedule within the same sprint cycle. That level of foresight is what separates good project management from reactive problem management.
What tangible results or business impact have you seen since the project was completed?
The ROI case we presented to our board was conservative by design.

The operational efficiency gains in particular have exceeded the model, in part because the quality of the data the new platform generates supports decisions that the previous system could not.
What did you like most about working with this company?
The willingness to be direct. When our requirements were unclear they said so. When our priorities were contradictory they explained why. When a technical approach we had assumed was the right one turned out to have significant downsides, they told us before we had committed to it. That kind of intellectual honesty is what I look for in a long-term technology partner.
Would you recommend this company to others, and would you work with them again?
Yes. I would add the context that this is not the cheapest option in the market and they are selective about the engagements they take on. If your primary criterion is price, there are alternatives. If you want a technology partner who can be trusted with a complex Software Development programme in the Legal Services space and will deliver against a serious brief, this is the team.
