When custom is worth it
Most companies should buy off-the-shelf. Accounting, payroll, email — these problems look the same everywhere, and a product serving ten thousand customers will always be more complete than something you build for yourself.
Custom is worth it when the process is your competitive advantage, or when it is distinctive enough that no product on the market describes it correctly. A travel agency that needs to query several airlines at once and merge the results under its own rules cannot buy that. Neither can a manufacturer tracking warranty claims across a network of technicians and dealers over Zalo.
A simple test: if you are exporting data to Excel every day to finish work your current system cannot do, your process has outgrown what is available off the shelf.
How we work
We start with business analysis, not with code. This phase usually takes two to four weeks and produces three things: a description of the process as it works today, a prioritised requirements list, and an outline system architecture.
Most software projects fail not because the code is wrong but because the wrong thing was built. Correcting a misunderstanding during analysis costs a few meetings; correcting the same misunderstanding after the code is written costs months.
Development then runs in two-week sprints, each ending with something that actually runs. Not a demo — it deploys to staging and your people can click through it. That keeps mistakes surfacing early, while they are still cheap.
Technology
We pick the stack for the problem rather than out of habit. But we also avoid anything only one person on the team knows: the system will outlive the project, and whoever maintains it is usually not the person who wrote it.
| Layer | Commonly used |
|---|---|
| Web front-end | React, Next.js, Vue, Angular |
| Mobile | Flutter, React Native |
| Back-end | Node.js, Laravel, Django, Ruby, .NET |
| Databases | PostgreSQL, MongoDB, vector databases for AI workloads |
| Infrastructure | AWS, Google Cloud, Azure, Docker, Kubernetes |
The list is broad because the projects were: a B2B booking platform, a healthcare application, a 3D product-configurator storefront, and a Zalo Mini App. No single stack is right for all four.
What you receive
The source code is yours, in your repository, with full access. That is a contract term, not a verbal understanding.
Alongside the code: architecture and API documentation, setup instructions that let someone rebuild the system from scratch, database migration scripts, and CI/CD configuration. The point of that package is that another team — including your own — can take over without needing to call us.
After go-live there is a warranty period, and a separate maintenance agreement if you want one. But maintenance should be a choice, not a dependency.
