Project summary: Our growth into new markets required a multi-currency, multi-language commerce platform that our previous vendor had promised but never delivered.

The thing I appreciate most in retrospect is that they were honest when something was harder than expected. Twice during the project the team came to us proactively to say that a particular component needed more time to do properly and explained why cutting corners would create problems later. We gave them the time. Both decisions were correct. The resulting product is solid and we have had none of the post-launch instability that plagued our last two technology projects.

PROS

Senior engineers on our account throughout the entire project rather than a bait-and-switch to juniors after contract signing, transparent reporting, realistic estimates that proved accurate

CONS

We underestimated the internal resource commitment required on our side during discovery — the team warned us, we did not listen fully, and the first sprint was slower as a result

Questions & Answers

Please describe your company, your role, and the industry you operate in.
As Director of Engineering at Sejong Digital Corp, I manage a cross-functional technology team serving our Retail & E-commerce clients from Busan, South Korea. We are a commercially focused organisation and every technology decision we make is evaluated against a clear business case. We needed a partner who understood that context, not just the technical brief.
What specific problem or business challenge led you to hire this company?
We had a product concept validated by market research but no clear path to build it within our budget and timeline constraints. Our Retail & E-commerce competitors were moving quickly and we could not afford to spend eighteen months finding out a generalist agency could not execute the CMS Development work our product required.
What services did the company provide for your project?
The core engagement was CMS Development but expanded to include technical consultancy during the discovery phase, which helped us refine the requirements significantly before development began. They also took responsibility for coordinating with our third-party data providers, which removed a significant coordination burden from our internal team.
Why did you choose this company over other providers you considered?
Their portfolio included two projects that were sufficiently close to our own brief in terms of complexity, CMS Development scope, and Retail & E-commerce context that we felt confident they understood what we were asking. The proposal was technically rigorous, the pricing was transparent, and the proposed team structure gave us senior engineers throughout rather than just for the pitch.
How clearly did the company understand your requirements and business goals?
Better than we did at the start, which sounds like an exaggeration but is genuinely accurate. The discovery workshop they ran surfaced assumptions we had not examined and contradictions in our requirements that would have caused real problems mid-development. The functional specification they produced was the clearest articulation of our product that we had seen written down.
How was your overall experience with their communication and project management?
Communication was handled primarily asynchronously given the time zone difference between Busan, South Korea and the team's base, but it was managed so well that the gap rarely felt like a constraint. Written updates were clear and timely, escalations were handled promptly, and we never had to chase for a status update. The cadence was exactly right — enough to feel informed, not so much that it created overhead.
Did the company deliver the project on time and within your expected budget?
The project landed on the agreed delivery date and within the approved budget. We did add scope during the engagement — two features that became apparent as essential during user testing — and those were quoted, approved, and delivered without affecting the original scope timeline. That kind of clean change management is not something you can take for granted.
What tangible results or business impact have you seen since the project was completed?
The most direct measure is that the problem we hired them to solve no longer exists. Beyond that, the new CMS Development platform has reduced our operational overhead measurably, our team spends less time managing incidents and more time on product development, and we have been able to onboard two new enterprise clients who had previously cited our technical limitations as a barrier.
What did you like most about working with this company?
The quality of the written communication. This matters more than most clients articulate. Clear, concise, technically accurate updates that our non-technical stakeholders could read and understand. Proposals and change requests that made the decision obvious rather than obscuring it in jargon. That communication quality reduced our internal coordination overhead significantly.
Would you recommend this company to others, and would you work with them again?
Absolutely. I would recommend them with a specific note that the quality of the discovery process is where the value starts. Clients who invest properly in that phase will get the most out of the engagement. We made that investment and the returns are evident in the quality of what was delivered.
