I'm the founder and lead instructor at CodeHunters, and I'll be the one teaching your course. With 10+ years building systems at companies like Morgan Stanley, Tesco, SAP, and Adevinta, I've designed infrastructure from scratch, led engineering teams, and migrated entire platforms across cloud providers. But what really drives me is sharing this knowledge. I've been teaching since my university days and haven't stopped since.
I'm obsessed with learning. You'll find me absorbing new technical content on the treadmill at the gym, during my commute, sometimes even while walking. I train myself actively every single day because technology never stands still, and neither do I. This isn't a side gig for me. Teaching is my passion, and I personally deliver every training session unless a larger group requires additional instructors I've hand-selected.
My expertise spans the full stack: backend (Java, Kotlin, Spring), DevOps and cloud infrastructure (AWS, Azure, GCP), containerization (Docker, Kubernetes), automation (Terraform, CI/CD), frontend (React, Angular), databases, system design, and technical leadership. I've built fraud detection systems, designed blue-green deployments, migrated services across clouds, and led teams through architectural decisions. Now I bring all of that real-world experience into the classroom, or to your office. I regularly travel across the EU to deliver in-person corporate training.
When you work with CodeHunters, you're learning directly from someone who lives and breathes this stuff. Beyond teaching, I still design and ship software, lead engineering teams, and help organizations adopt AI tools like Windsurf, Claude, and GitHub Copilot in a safe, practical way. Whether you're here for hands-on IT training, production-grade software development, or AI automation, you get someone who has done the work, not just read about it.
