Over the past 7 years, I have built and scaled a Kotlin education model that has trained over 20,000 developers and helped expand Kotlin adoption across education, industry, and the global community.
My work focuses on enabling developers to learn Kotlin through hands-on system implementation, structured feedback, and real-world collaboration. This model has also trained educators who now lead their own Kotlin courses, helping multiply its impact.
I maintain an open Kotlin and Spring application platform (580+ GitHub stars, 100+ forks) where learners contribute to real production systems, connecting education with real-world Kotlin development practices.
I also launched Hero Tech Course in Berlin, expanding this education model internationally, and supported organizations transitioning from Java to Kotlin by providing codebase analysis, customized training, and migration enablement.
In addition, I founded and operate YouthCon, a conference that mentors junior developers through the process of preparing and delivering their first technical talks, helping grow the next generation of contributors to the Kotlin ecosystem.
Through curriculum design, platform development, mentorship, and migration support, my goal has been to help developers not only learn Kotlin, but actively contribute to its ecosystem.
