About this gig

Need a secure, scalable Java backend built by someone who ships this for a living? I build Spring Boot REST APIs and microservices for startups, businesses, and SaaS products. The same kind of systems I have delivered to production for a major bank and multinational FMCG brands.

What I deliver:

  • REST APIs with Java Spring Boot
  • Spring Security + JWT authentication and role-based access
  • Microservices architecture: API gateway, service discovery, config
  • PostgreSQL / MySQL schema design and integration
  • Payment and third-party API integrations
  • Clean layered architecture, unit tests, Dockerized deployment
  • Documented source code

Why me:

  • 3+ years of professional experience with a team-lead background
  • Production-grade code, not tutorial code
  • Clear communication, honest timelines, post-delivery support

Message me with your requirements before ordering. I will confirm exact scope, price, and timeline first.
