Over deze dienst

Need a backend built right or an existing one fixed, cleaned up, and made production-ready?

I'm a backend engineer who has shipped production systems end-to-end in Node.js, NestJS, and Python/FastAPI on PostgreSQL. I build APIs that are secure, well-structured, and don't surprise you in production.

What I can help with:

REST APIs and backend services (Node.js, NestJS, Express, FastAPI)

PostgreSQL schema design, queries, and migrations (TypeORM/Prisma)

Authentication, roles, and permissions (JWT, guards)

Third-party & API integrations (payments, Slack, email, maps, IoT, and more)

Bug fixes, refactoring, performance and security cleanup

Deployment (Docker, PM2, AWS)

I've built multi-tenant SaaS backends, real-time tracking, and HR automation as the sole engineer so I'm comfortable owning a backend from schema to deployment.

Message me with what you're building (or what's broken) and I'll map the fastest, cleanest path KISS, no over-engineering.
