Need a backend that works in production — not just on your laptop? I'm a Backend Developer who builds reliable APIs in Java/Spring Boot and Python/FastAPI, and rescues the ones that are quietly falling apart. If your backend is slow, buggy, or scary to deploy, I can help. What I build for clients: REST APIs that handle real traffic (Spring Boot, FastAPI) Database layers that don't choke under load (PostgreSQL, MySQL, SQL tuning, indexing) Clean Docker + Docker Compose setups your team can actually maintain Kubernetes deployments and troubleshooting AWS deployments with NGINX, Redis, and proper reverse proxy configs Third-party API integrations that don't silently fail Backend automation scripts that save your team real hours Where I tend to add the most value — real-world debugging: Session handling and autosave issues, token expiry bugs, Tomcat misconfigurations, Gradle build problems, slow queries in production, containers that work locally but break in K8s, reverse proxy headaches. The kind of issues that aren't on Stack Overflow. How I work: Clear, frequent communication — you'll always know where things stand Clean, maintainable code — no shortcuts that haunt you in 6 months Honest timelines — I tell you what's realistic, not what sounds good I finish what I start Tech I work with daily: Java, Spring Boot, Python, FastAPI, PostgreSQL, MySQL, Redis, Docker, Kubernetes, AWS, Linux, NGINX, REST APIs, SQL. Whether you need a new API built from scratch, a production bug fixed before it bites you again, or someone to clean up a messy deployment — send me a message describing what you're working on. I'll reply with honest thoughts on whether I'm the right fit and how I'd approach it.
