Why Weavelinx
Resource modelling, versioning, rate limiting, auth middleware, and OpenAPI docs. APIs that front-end teams enjoy using.
PostgreSQL schema design, query optimisation, migrations, and ORM vs raw SQL decisions made correctly.
BullMQ, Redis, and scheduled jobs — for anything that should not block the request cycle.
JWT, refresh tokens, OAuth2/OIDC, RBAC, and input validation at the boundary — not deep inside the code.
Docker, CI/CD pipelines, environment configuration, and VPS or managed cloud setup.
Query profiling, caching strategy, structured logging, and metrics from day one.
How it works
What does the API need to do? What database? What existing codebase if any? We size the role from there.
We match against our bench and send profiles with code samples and previous API work examples.
Live architecture discussion or take-home API task — your choice. We recommend the former for senior hires.
Environment set up, codebase walked through, and first PR up within 3 days of start.
Common questions
Our developers are fluent in both. Express/Fastify for leaner APIs, NestJS for larger codebases where structure is worth the overhead.
Yes. Many engagements involve inheriting an existing codebase, profiling it, and improving it incrementally.
Yes — WebSocket servers, Server-Sent Events, and polling strategies. Use cases include chat, notifications, and live dashboards.
MySQL, MongoDB, SQLite, Redis (as both cache and queue), and DynamoDB for AWS-native setups.
