I will build a spring boot rest api or java microservice

Need a clean, well-tested Spring Boot backend that your team can actually maintain? That's what I build every day.

I'm a Java team lead with 9+ years of backend experience. I've built Kafka-based Spring Boot microservices on AWS for a large US retailer (400k+ users, a shipment pipeline handling 100k+ orders a day), and today I lead a backend team on a government platform.

What you get:

• A Spring Boot 3 service with a clear package structure
• REST endpoints with validation and proper error handling
• Unit and integration tests
• Database with migrations (PostgreSQL or MySQL)
• Docker setup and API docs (OpenAPI/Swagger)
• Kafka producers/consumers, auth and AWS deployment in the bigger package
• AI features with Spring AI: OpenAI, Claude or Gemini calls, chatbots and document Q&A (RAG)
• A short README so anyone can run it

I also take smaller jobs: fixing a bug in an existing Spring service, upgrading an old Spring version, or speeding up slow queries. Message me with the details first and I'll tell you honestly what fits.

I work on GMT+4 time and reply within a few hours.
