About this gig

I will design and develop scalable, production-ready Java backend services using Spring Boot, Kafka, PostgreSQL, and modern microservice patterns.

With 10+ years of experience as a Senior Java Engineer in fintech, data engineering, and high-load distributed systems, I provide clean architecture, reliable delivery, and enterprise-level quality.

What I can build for you:

  • RESTful APIs & backend logic
  • Microservices architecture (Spring Boot / Cloud)
  • Kafka producers, consumers, event streams
  • PostgreSQL schema design, JPA, query optimization
  • Authentication & authorization (JWT, Keycloak, OAuth2)
  • Docker & container-ready deployments
  • Serverless & AWS integrations
  • Migration of monoliths to microservices
  • Refactoring legacy Java codebases

All deliverables include production-grade code quality and documentation.

Why work with me?

  • Senior Java/Spring Boot developer (10+ years)
  • Real-world experience with high-load, low-latency systems
  • Strong architecture & clean code
  • Excellent communication, daily updates
  • 100% custom development no boilerplate shortcuts
  • Ready for long-term contracting

I’m a Java Backend Engineer with 6+ years of experience delivering production-grade systems in fintech, healthcare, media, and SaaS. I specialize in Spring Boot microservices, Kafka pipelines, PostgreSQL optimization, and cloud-native deployments (AWS, Docker, Kubernetes). I’ve integrated 20+ third-party APIs, migrated legacy systems, and worked under strict compliance standards. I also have experience with fullstack delivery using Angular when needed. While my projects are under NDA, I can provide detailed architectural overviews and explain my impact. Let’s build something stable, secure, an
