What I'm looking for

I’m looking to build resilient backend systems with Java, Spring, SQL, and AWS—collaborating through code reviews, designing REST APIs, and solving complex data integration problems that improve performance and user experience.

I’m an ambitious, results-driven Java Developer and Software Engineer based in Greece, focused on building resilient backend systems that connect real-world platforms to deliver measurable outcomes.

Since 2019, I’ve delivered data integration and API-driven solutions—converting 2D canvas designs into EnergyPlus simulation files for large-scale energy performance analysis, and designing custom REST APIs for market data integration.

In recent roles, I’ve strengthened platform reliability through code reviews, API design discussions, and troubleshooting. I’ve also contributed to feedback boards with integrated voting functionality and supported cloud deployment using AWS.

Earlier experience includes developing and optimizing online financial reporting and a web-based POS ordering system, and mentoring junior developers while supporting banking risk management software as a Full Stack Developer & Team Lead.
