About this gig

Do you need a clean, secure and production-ready backend API for your web app, mobile app, SaaS product or startup MVP?


I can help you build backend systems that go beyond basic CRUD. I work with Node.js, NestJS, Express.js, PostgreSQL, MongoDB, Redis, REST APIs, authentication, role-based access, payment integrations, webhooks and deployment-ready architecture.


I am a Full-Stack and DevOps Engineer with 6+ years of experience building production systems across fintech, ed-tech and SaaS. I have worked on backend services, payment systems, AI integrations, real-time features, Kubernetes deployments, CI/CD pipelines and cloud infrastructure.


What I can help with:


  • Backend API development
  • Node.js, NestJS and Express.js APIs
  • PostgreSQL, MongoDB or MySQL database design
  • Authentication and authorization
  • Role-based access control
  • Payment and webhook integrations
  • Redis caching
  • Real-time APIs with WebSockets
  • API bug fixes
  • Backend refactoring
  • SaaS MVP backend foundations
  • API documentation and setup notes


My process:


  1. I understand your current idea, app or backend issue
  2. I confirm the exact scope before starting
  3. I build or fix the backend feature
  4. I test
