Backend & API Development (Node.js / NestJS)
Backend engineering is my specialty. I have architected microservice platforms for a national F&B company supporting 1,300+ distributors, real-time WebSocket messaging for a DTH provider, and automated video-processing pipelines on AWS. If your product needs an API that is fast, secure, well-documented and built to scale, this is the service.
Who this is for
- Frontend or mobile teams that need a reliable backend partner
- Startups whose API has become the bottleneck
- Companies moving from a monolith to services or event-driven architecture
What you get
- REST API design with OpenAPI/Swagger documentation
- NestJS modules, guards, validation and testing
- Microservices and event-driven architecture (queues, pub/sub)
- Real-time features with WebSockets / Socket.IO
- Authentication (JWT, OAuth2), rate limiting, caching
- Database design, query optimisation and migrations
- Third-party integrations (payments, CRMs, Slack, Jira, Zapier)
Outcomes
- APIs that stay fast under load and are easy for any frontend to consume
- Fewer production incidents thanks to validation, typing and tests
- A backend your next engineers can onboard onto in days, not months
Backend & APIs: common questions
Can you work with our existing frontend / mobile team?
Yes. I frequently act as the backend lead for teams that already have frontend or mobile developers, providing documented APIs, staging environments and clear release notes.
Do you write tests?
Yes — unit tests for business logic and end-to-end tests for critical API flows, wired into CI so regressions are caught before deploy.
