ABOUT ME
Java expert focused on clean architecture, performance, and mentoring.
Java expert focused on clean architecture, performance, and mentoring.
I’ve been writing code for over 17 years, growing into roles like Principal Engineer and Java Technical Lead. I’ve helped non-developers turn their dreams into developer careers, supported juniors at the start of their journey, and mentored entire teams. I approach mentoring with kindness, precision, and attention to detail—and problems tend to shy away when I’m around.
