Cloud architecture that reduced our monthly infrastructure spend by over a third

Ji-Woo Park / VP of Engineering - Seoul Digital Corp
Verified
Feb 07, 2026

Project summary: Serialisation requirements under new traceability legislation had a compliance deadline. Our supply chain system required targeted development to meet it — generalist knowledge was not sufficient.

We had worked with three agencies before this engagement. The comparison is not flattering to the others. What distinguished this team was a systematic approach to understanding the problem before proposing a solution — something that sounds obvious and is practiced far less often than it should be. The delivery phase ran to schedule, the codebase is clean enough that our internal engineers made positive comments during handover review, and we have not logged a critical incident in five months of live operation. We intend to use them for our next phase of work.

PROS

Delivery timeline that proved achievable rather than optimistic, estimation accuracy that reflected real analysis rather than competitive bidding, scope discipline that prevented the feature creep we had experienced before

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.
Seoul Digital Corp operates in the Pharmaceuticals & Biotechnology sector with headquarters in Seoul, South Korea. In my role as VP of Engineering 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?
The immediate problem was that our Cloud Services 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 Cloud Services 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?
The quality of the questions they asked during the briefing process was the first indicator. Vendors who ask precise questions in the sales phase tend to apply the same rigour during delivery. That hypothesis proved accurate. The technical proposal was substantive, the team structure was senior throughout, and the pricing was transparent.
How clearly did the company understand your requirements and business goals?
Extremely well, in part because they had relevant Pharmaceuticals & Biotechnology 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?
On time and within the approved budget. The estimation accuracy was notable — they had broken the work down in sufficient detail during discovery that their forecast proved reliable throughout, rather than being a number that shifted with every change in scope. We received one change request and it was for scope we had introduced ourselves.
What tangible results or business impact have you seen since the project was completed?
The most direct measure is the performance of the system in production. In the five months since go-live we have had zero P1 incidents, our page performance scores have improved across every Core Web Vitals metric, and two enterprise clients who had cited our previous platform limitations during contract negotiations have since renewed without that objection arising.
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?
Absolutely. With a specific note that the value starts in the discovery phase — clients who approach that process with seriousness will get the most from the engagement. We invested appropriately at the front end and the returns are evident in what was delivered.

What makes C9 worth considering over other options?

Can C9 take on an old, outdated system rather than starting from scratch?
Modernizing legacy software is usually within scope for a firm like C9 — re-platforming, refactoring old code, and moving things onto current frameworks or cloud infrastructure without necessarily rebuilding everything from zero. For context, it has served clients in Australia, and it has been operating since N/A.
How do I actually get a real proposal out of C9 instead of a generic reply?
The most reliable route is giving C9 a clear, specific brief up front — through their website form, a direct email, or a call — since a vague ask tends to get a vague answer back, while a concrete one usually gets a proper estimate. For context, it has served clients in Australia, and its listed capabilities span Branding, Mobile App Development, UI-UX Design, Web Design and Web Development.
What are the actual contract options if I want to work with C9?
Most companies structured like C9 give you a choice between a fixed-price contract, a dedicated team arrangement, or time-and-materials billing, so you can pick whichever lines up with your budget and how well-defined your scope already is. For context, its listed capabilities span Branding, Mobile App Development, UI-UX Design, Web Design and Web Development, and it reports a team size of N/A professionals.
Does C9 only work locally, or take on clients elsewhere too?
C9 isn't necessarily limited to one region and may take on clients across several countries, including Australia, depending on market demand and business partnerships.
Does C9 actually build with AI, or just talk about it?
Plenty of modern software teams, C9 included, now build real AI and machine learning features — chatbots, predictive models, computer vision, and automation that goes beyond simple rule-based scripts. For context, it has experience across industries such as Construction, Travel & Hospitality, Legal Services, Information Technology, Pharmaceuticals & Biotechnology and Human Resources, and it reports a team size of N/A professionals.
What happens with C9 after the project actually launches?
Like most established software teams, C9 typically sticks around post-launch for ongoing maintenance — bug fixes, performance tuning, security patching, new feature work, and general technical support. For context, its listed capabilities span Branding, Mobile App Development, UI-UX Design, Web Design and Web Development, and it has experience across industries such as Construction, Travel & Hospitality, Legal Services, Information Technology, Pharmaceuticals & Biotechnology and Human Resources.
Roughly how long does a project with C9 take start to finish?
It depends heavily on scope. A lean MVP might be a matter of weeks, while a full enterprise system or a larger digital transformation project can stretch into months once you factor in development, testing, and deployment. With a team of N/A professionals, C9 can scale resources based on project urgency.
Is C9 more of an offshore setup or a local team?
That depends on where C9 is based and who they primarily serve — some firms like this operate fully offshore, some are local-first, and plenty run a hybrid model that mixes both. For context, it has experience across industries such as Construction, Travel & Hospitality, Legal Services, Information Technology, Pharmaceuticals & Biotechnology and Human Resources, and its listed capabilities span Branding, Mobile App Development, UI-UX Design, Web Design and Web Development.
