Backend Developer

What I do

I build REST APIs and integrations for backend-heavy products. Every project is tested, documented, and ready to deploy.

• Spring Boot REST APIs (auth, validation, error handling)
• Third-party integrations (payments, CRMs, external APIs)
• PostgreSQL database design and optimization
• Docker containerization and CI/CD basics

Recent work

• Spring Boot Payment Service — JWT auth, OpenAPI docs, tests, Docker. View code
• More coming: Stripe integration, scheduled workers, API design patterns.
