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.
