About this gig

Need a reliable backend that's built to grow? I'm a Senior Backend Developer who builds production systems with Java Spring Boot every day. I design APIs, lead feature delivery and keep services running on Kubernetes and AWS.


What I can do for you:

- REST APIs with Spring Boot: design, build and document (Swagger/OpenAPI)

- Third-party integrations: payment providers, CRMs and external APIs

- Databases: SQL (Oracle, MariaDB) and NoSQL (MongoDB, Redis, DynamoDB)

- Deployment with Docker, Kubernetes, Jenkins CI/CD or AWS (Lambda, EC2, API Gateway)

- AI features with AWS Bedrock and vector search (Pinecone)

- Bug fixes, refactoring and performance work on existing Java code


Why work with me:

- Clean, tested and maintainable code

- Clear communication and regular progress updates

- I think about your business goals, not just the ticket


Message me before ordering so we can scope your project and set a realistic timeline.
