What I'm looking for

I’m looking for a team where I can own backend services end-to-end—secure APIs, AWS deployments, and thoughtful system design—while using AI-assisted tooling to improve code quality, audits, and delivery speed.

I’m a Java backend developer who designs, builds, and operates live production microservices platforms end to end. I work across REST API design, JWT security hardening (token versioning and refresh-token race-condition fixes), and real-time session invalidation with SSE push notifications.

I’ve built a B2B construction-materials trading platform with Spring Boot 3 microservices on AWS, including a dynamic weighted pricing & discount engine (Strategy pattern), Flyway database migrations, and performance-focused caching with Caffeine. I also bring DevOps ownership—Docker/Nginx setup, SSL with Let’s Encrypt, automated MySQL backups from EC2 to S3, and production security auditing—while actively using Claude and GitHub Copilot across the SDLC.
