Please describe your company, your role, and the industry you operate in.
Han River Digital Corp has been operating in Mining & Metals for a while now, headquartered in Busan, South Korea. As VP of Engineering I sit across both strategic planning and day-to-day technology delivery. We hold our vendors to a high bar because our own clients hold us to one — it's only fair to expect the same discipline from partners.
What specific problem or business challenge led you to hire this company?
We had a clear product direction for our next stage of growth in Mining & Metals, but not the internal engineering depth to actually execute it. The Mobile App Development piece specifically needed specialist skills we couldn't realistically hire for on the timeline our business plan demanded.
What services did the company provide for your project?
Mainly Mobile App Development, with some adjacent architecture and QA work folded in. They owned the whole thing from requirements to go-live, including hooking it into four of our existing systems. Not needing a second vendor to cover that ground was genuinely useful, both cost-wise and logistically.
Why did you choose this company over other providers you considered?
We were coming off a failed engagement and went into vendor selection this time with a lot more scrutiny. We asked pointed questions about how they handle scope changes, how they estimate, how they communicate bad news. The answers were specific and consistent across everyone we spoke to on their team, which gave us confidence it wasn't a rehearsed pitch.
How clearly did the company understand your requirements and business goals?
Better than we understood them ourselves, honestly. The workshops they ran surfaced assumptions we'd never questioned and exposed a few requirements that flatly contradicted each other. Sorting that out before development started saved us from what would have been serious rework later.
How was your overall experience with their communication and project management?
The most structured project management I've dealt with from any outside vendor. Sprint planning was tight, acceptance criteria were specific, and retrospectives actually led to changes rather than just being a box to tick. The backlog and risk register were both treated as live tools, not paperwork. I never once had to chase a status update.
Did the company deliver the project on time and within your expected budget?
On time and inside the approved budget. Their estimating was notably accurate — they'd broken the work down in enough detail during discovery that the forecast held up the whole way through, instead of drifting with every small change. We had exactly one change request, and it was for scope we added ourselves.
What tangible results or business impact have you seen since the project was completed?
Hard to isolate perfectly given everything else going on in the business, but the numbers we can attribute directly to the Mobile App Development work are solid: session duration up, conversion up, error rate down, and our NPS for that touchpoint has moved noticeably. Our account managers say it's coming up positively in client conversations now too.
What did you like most about working with this company?
Their willingness to just be direct. If our requirements were unclear, they said so. If our priorities contradicted each other, they explained why. If an approach we'd assumed was right actually had real downsides, they told us before we'd committed to it. That kind of honesty is exactly what I look for in a long-term partner.
Would you recommend this company to others, and would you work with them again?
Absolutely, with one caveat worth mentioning: the value really starts in discovery, so clients who take that phase seriously will get the most out of it. We put real effort in upfront and it clearly paid off in what got delivered.
