Summary
🤩
Rockstar🎓
Top SchoolPeter Ferenczy is a seasoned Java developer based in Budapest with 12 years of professional experience building and modernizing enterprise systems. He currently maintains and evolves Deutsche Telekom’s internal platforms, driving migration from JavaEE/WildFly to Spring Boot and exploring reactive options like Vert.x while preparing architectures for cloud and modularization. His background spans microservices, Docker, JWT/hystrix patterns, and testing with Mockito and SoapUI from his Precognox backend work, plus early-career systems programming in C/C++ and REXX for bank-grade integrations. An active problem-solver, he has also contributed front-end fixes to the popular tinycon library—adding Retina support and cross-browser fallbacks—demonstrating full-stack instincts beyond his Java focus. Comfortable in agile teams and stepping into scrum master responsibilities, he blends hands-on coding with operational and architectural thinking. Colleagues value him for pragmatic migrations, legacy-modernization know-how, and a willingness to experiment with new tech stacks.
