What sets us apart.
✓
Senior engineers, not juniorsYour project is handled by developers with 4+ years of Node.js production experience — not freshers learning on your dime.
✓
Performance-engineeredWe profile, benchmark and optimise from day one — async patterns, connection pooling and caching mean your API stays fast under load.
✓
Thorough documentationEvery API is documented with Swagger/OpenAPI — your team and future developers will never be guessing about endpoints.
✓
Test coverage from day oneUnit tests with Jest, integration tests with Supertest and CI pipelines that catch regressions before they reach production.
✓
Microservices-readyWe architect for the future — services that can be split, containerised and scaled independently as your product grows.
✓
Transparent communicationFortnightly demos, a shared project board and Slack/WhatsApp access — no black-box development cycles.
