What I'm looking for

I’m looking for fast moving teams where every opinion matters, where true teamwork is the standard. I want to work on great products with people who truly care both about the product and also about the team creating it. I’m looking for companies where curiosity and ownership are genuinely valued.

I’m a software engineer specializing in backend development with Java/Spring Boot and Python/FastAPI. I build RESTful APIs, integrate public APIs, and design OpenAPI specifications to keep systems reliable and clear.

In my work, I’ve implemented distributed Java/Spring Boot backends, created RESTful APIs, and added WebSocket real-time communication for up to 1000 simultaneous clients. I work across relational and NoSQL data stores, including PostgreSQL (with Hibernate) and ArangoDB.

I care about production-ready delivery: I use Docker for containerization and deployment, JVM ecosystem tools like Maven and Gradle, and I support web accessibility (WCAG 2.1 AA) through accessible frontend components. I collaborate in Agile/Scrum teams and enjoy turning requirements into maintainable systems—whether that’s backend services, testing tools, or code quality improvements.
