About me
I am a Software Developer specialized in backend architecture, API integration, and ETL processes. I focus on building robust data pipelines and connecting external services to automate workflows and solve complex technical challenges.
My core stack includes Java, Spring Boot, and deep expertise in relational databases (SQL/DBeaver) for efficient data modeling and extraction. Whether you need to consume complex third-party APIs, clean and transform large datasets, or build a scalable web backend from scratch, I deliver clean, maintainable, and well-documented code.
