We are deliberately a small senior team rather than a large mixed one. For the current size and the specific people who would work on your project, ask on a call — you should meet them before committing anyway.

What languages do you work in?

English and Vietnamese. Delivery artefacts — specs, code review, documentation, demos — default to English unless you prefer otherwise.

Vietnam, working with clients internationally. We are remote-first with clients and coordinate in writing by default.

Can we talk to a reference?

Ask on a call. We will connect you with clients who have agreed to speak, rather than publishing names and quotes without their involvement.

About SofinWave

SofinWave is a software outsourcing company based in Vietnam. We work with companies in the US, Europe, and Asia as an offshore team, a dedicated team inside their process, or individual engineers filling specific gaps. Our work is mostly on systems that already exist and already have users — the unglamorous, high-stakes kind.

How we work

These are the commitments that shape every engagement, and the ones we would want from a vendor ourselves.

We say what we think, including when the answer is that you should not hire us.
Estimates come after discovery, never from a brief alone.
Progress is demonstrated with running software rather than status reports.
Documentation and tests are part of the work, so handover is never a separate project.
You own all code and IP, and it lives in your repositories and accounts.

What we are good at

We are a small senior team rather than a large mixed one, which shapes the work we take. We are strongest on backend and platform work — architecture, integration, performance, and the operational side of getting a system to behave in production.

TypeScript and Node.js, React and Next.js on the front end.
Python and Go for services and data work.
PostgreSQL, Kubernetes, and AWS for the infrastructure underneath.
Fintech, e-commerce, logistics, SaaS platforms, and enterprise systems.

What we are not

We are not a body shop that can staff forty engineers next month, and we are not a design studio. If you need very large scale, or brand and product design as the primary deliverable, another partner will serve you better and we will say so early rather than late.

Working across time zones

We are in Vietnam at UTC+7, which does not change with daylight saving. That gives roughly half a working day of live overlap with Europe and edge-of-day overlap with the US East Coast. We run written-first communication so that progress does not depend on being awake at the same moment, and we schedule the live hours that do matter deliberately.
