I've built a full-stack banking application using React, TypeScript, Java 21, REST APIs, PostgreSQL, jOOQ, Docker, and automated testing. It supports account management, account creation, money transfers, and transaction history.

I designed REST APIs connecting the frontend to banking services and implemented atomic transfers with transaction handling and rollback to maintain data consistency. I also developed unit and integration tests with JUnit 5 and Testcontainers.

I've also created a thesis distribution and management platform for students, professors, and department staff, and collaborated on a doctor appointment booking application. In project-based work with Hellenic Organic Food, I contribute to web and email development based on project requirements.

Alongside software development, I teach English through private lessons, adapting explanations to feedback and communicating complex concepts clearly. I'm completing an Integrated Master's in Computer Engineering and Informatics at the University of Patras.
