Enterprise Software Engineering
Custom business systems built to a specification, from the data model up: internal platforms, back-office tooling, integrations and the interfaces that sit on top of them.
What the engagement looks like
Engagements usually begin with a written specification of the domain — the entities, the states they move through, and the rules that govern the transitions — because that document, not the framework choice, is what determines whether the system can be maintained in three years. Delivery is incremental against that specification, in an environment your team can run. Source code, schema migrations and deployment scripts belong to the client at every point in the engagement, and are handed over in a repository the client controls.
Typical work under this heading
- Domain modelling and written technical specification
- Back-office and internal operations platforms
- Modernisation of a legacy system in place, without a stop-the-world rewrite
- Data migration with a reconciliation report
- Automated test suites and continuous integration
What this page is not. It describes how 303 Team OÜ approaches this kind of work. It is not a claim about any particular client, past project or outcome — we name no clients and publish no case studies — and it contains no price, estimate, delivery date or service-level commitment. Those are agreed in writing, per engagement, after we have understood the problem.
Technologies we work in
- PHP
- Node.js
- Python
- React
- Next.js
- TypeScript
- PostgreSQL
- MySQL
Naming a technology here means we build with it. It is not a claim of certification, partnership or accreditation by its vendor — 303 Team OÜ holds none, and resells nothing.

Describe the system and the constraint you are up against. If the honest answer is that you do not need this work, that is the answer you will get.
