I will build scalable nodejs and nestjs backend apis


About this gig
Need a backend that stays fast and stable as your users grow? I build production-grade APIs and microservices in Node.js and NestJS.
I have 5+ years of professional backend experience, including SMS gateway services used by major banks, real-time CRM platforms and high-traffic brand campaigns.
What I can build for you:
- REST APIs and real-time features (Socket.IO, webhooks)
- Microservices with Kafka or Redis for async processing
- Authentication, roles and secure data handling
- Database design in PostgreSQL, MySQL, SQL Server or MongoDB, chosen to fit your data
- Third-party integrations: payments, messaging, external APIs
What you get:
- Clean, structured TypeScript code that your team can maintain
- API documentation (Swagger/Postman)
- Clear updates during the work, no disappearing
- Support after delivery
I understand every part of the systems I build, so I design for failure, not just the happy path.
Send me a message with what you're building and I'll reply with questions and a clear plan before you order.

FAQ
Can you work on my existing codebase?
Yes. I can add features, fix bugs, refactor or improve performance in an existing Node.js or NestJS project. Share access and I'll review it first.
Which databases do you work with?
PostgreSQL, MySQL, SQL Server, MongoDB and Redis. I'll recommend the one that fits your data, not just the one I like.
Will I get the full source code?
Yes. You own all the code. I deliver it through your Git repository or as a zip, with setup instructions.
Do you also deploy the backend?
The Premium package includes Docker setup. For full cloud deployment, see my DevOps gig or ask me for a custom offer.
