A testing partner who treated quality as seriously as we do

Maryam Al-Zahrani / Head of Innovation - Al-Salam Digital Solutions

Sep 09, 2025

Project summary: Our competitors had been investing in technology for two years and we needed to close a meaningful gap quickly without compromising on the quality of what we shipped.

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

Collaborative working style that made them feel like an extension of our team, excellent written communication for our async timezone relationship, clean and readable codebase

CONS

The initial project brief document they required was more detailed than we were used to providing, but in hindsight that rigour was part of why the project ran so smoothly

Questions & Answers

Please describe your company, your role, and the industry you operate in.
I lead technology at Al-Salam Digital Solutions, a mid-sized organisation in the Mining & Metals sector headquartered in Jeddah, Saudi Arabia. My remit as Head of Innovation covers everything from infrastructure to product development. We had reached a point where our internal engineering capacity was not sufficient to execute our roadmap without an experienced external partner.
What specific problem or business challenge led you to hire this company?
Our existing Quality Assurance & Testing capability had accumulated years of technical debt that was slowing every new feature to a crawl. Incident frequency was rising, developer confidence was falling, and we knew a rebuild was overdue. We needed a partner with the depth to do it properly rather than apply another layer of patches.
What services did the company provide for your project?
The full Quality Assurance & Testing lifecycle from discovery through to production deployment and hypercare support. This included requirements workshops, solution architecture, sprint-based development, QA and automated testing, deployment to our cloud environment, and a structured handover with documentation. They also provided a brief post-launch period of dedicated support which was genuinely useful.
Why did you choose this company over other providers you considered?
We evaluated four vendors in total. Two were eliminated after the technical assessment stage because their proposed architectures showed a surface-level understanding of what we needed. This team's proposal demonstrated genuine depth in Quality Assurance & Testing and specific knowledge of the Mining & Metals sector that the others could not match. The reference calls confirmed a consistent pattern of delivery.
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?
The project management was the best I have experienced in a vendor relationship. We had fortnightly sprint reviews with structured agendas, a shared backlog that we could inspect at any point, a risk register that was actively maintained rather than created at kickoff and never opened again, and a project manager who treated our time as something worth protecting. Communication was proactive, not reactive.
Did the company deliver the project on time and within your expected budget?
Yes. I will note that the original timeline was aggressive and I had privately expected a slip. They managed to hold it by making smart sequencing decisions early on that I only fully understood in retrospect. The budget discipline was equally good — we received a single change request for scope we had introduced ourselves and it was priced fairly.
What tangible results or business impact have you seen since the project was completed?
The ROI case we presented to our board assumed a payback period of eighteen months. Based on current trajectory we will hit that in under a year. The efficiency gains in our Mining & Metals operations have been more significant than the model projected, partly because the quality of the data coming out of the new system is enabling decisions we could not make before.
What did you like most about working with this company?
Their ability to hold the business objective in mind alongside the technical task. I have worked with technically excellent agencies who lost the thread of what we were actually trying to achieve. This team never did. Every architectural decision, every trade-off conversation, every prioritisation discussion was anchored to the outcome we had agreed at the start.
Would you recommend this company to others, and would you work with them again?
Unreservedly. We are in active conversation about the next phase of work and I expect this to become a multi-year partnership. For any organisation in the Mining & Metals space looking for a Quality Assurance & Testing partner who combines technical rigour with genuine commercial awareness, I would put this team at the top of the shortlist.

Prototype-to-handoff process that our developers actually appreciated

PROS

Engineering quality that our internal team can maintain without calling the vendor, thorough documentation, proactive risk identification throughout the project

CONS

The volume of quality documentation they produced was genuinely impressive but also meant our team needed dedicated time to review it properly — a minor process point, not a complaint

Questions & Answers

Please describe your company, your role, and the industry you operate in.
HanRiver Tech Co Ltd operates across the Gaming & Gambling sector with offices in Seoul, South Korea. In my capacity as CTO I oversee both the strategic and operational technology agenda. We are a growth-stage business that needed a development partner capable of scaling with us rather than constraining us.
What specific problem or business challenge led you to hire this company?
The immediate trigger was a performance failure during our peak trading period that cost us measurably in both revenue and client trust. The root cause was architectural and our internal team did not have the UI/UX Design expertise to address it properly. We needed specialists.
What services did the company provide for your project?
End-to-end UI/UX Design delivery with a particular emphasis on the integration layer that connected the new build to our existing Gaming & Gambling infrastructure. They also provided UI/UX input that was not in the original scope but which they offered proactively because they could see it would affect adoption. That kind of initiative was characteristic of how they approached the whole engagement.
Why did you choose this company over other providers you considered?
Honestly, the quality of the questions they asked during the briefing process set them apart. Most vendors listen to the brief and come back with a solution to exactly what you described. This team came back with a solution to what we actually needed, which turned out to be somewhat different. That kind of consultative instinct is what we were looking for.
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?
Professional and efficient. We used a shared project management tool that gave our stakeholders visibility without requiring them to attend every meeting. The project manager had a clear escalation path and used it appropriately. The only time I needed to intervene directly was when I chose to, not because something had been missed.
Did the company deliver the project on time and within your expected budget?
Yes on both counts. There was one sprint where a third-party integration took longer than scoped because of undocumented API behaviour on the vendor side. The team flagged it immediately, proposed two mitigation options, and we agreed on an approach that recovered the timeline within two weeks. That is how scope issues should be handled and rarely are.
What tangible results or business impact have you seen since the project was completed?
We went live three months ago. In that time we have not had a single P1 incident, our page performance scores have improved across every measure, and the feature we had deprioritised for years because the old architecture made it too complex to implement is now in our next sprint. The platform they built has opened up our roadmap in a way we had not anticipated.
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?
I recommend them to anyone who asks and occasionally to people who do not. The combination of UI/UX Design expertise, Gaming & Gambling domain knowledge, and delivery discipline is genuinely difficult to find. We found it here and we intend to keep it.
