Hi, I’m a backend software engineer with 5 years of experience building and maintaining APIs and backend systems. I mainly work with Java/Kotlin, Spring Boot, Python, and FastAPI. I can help with REST APIs, database integration (PostgreSQL, MySQL, MongoDB), API security, debugging, legacy system refactoring, and backend migrations. I’ve worked mainly on e-commerce and SaaS projects and also have experience with Kubernetes, Helm, GitHub Actions, Azure, GCP, and AWS.
