Über mich
Backend Developer (Java/Kotlin) — I build systems end-to-end: from database design to a working, deployed API with Spring Boot. I can also connect it to a frontend or mobile app for one finished product.
What I offer:
• REST API development (Spring Boot)
• Database design & queries (PostgreSQL/MySQL)
• Bug fixes in Java/Kotlin/Android apps
• Basic frontend integration (HTML/CSS/Tailwind)
Early in my freelance journey — sharp pricing, full focus on your project, clear communication. Message me your scope for a quick estimate.
