The future of development isn't about memorizing syntax —AI can handle that. What truly matters now are the skills machines can't replicate: system design, architectural thinking, problem decomposition, and understanding the bigger picture. Our courses focus on these critical competencies that will define successful developers in the AI era.


Whether you're starting your journey or you're a seasoned professional adapting to this new landscape, our experienced instructors bring years of real-world expertise to help you master what matters most. We teach you to think like an architect, design scalable systems, make strategic technical decisions, and lead projects with confidence.


With courses in English or Hungarian covering Java, DevOps, Cloud, System Design, and more, we provide comprehensive training that prepares you for the reality of modern development—where understanding trade-offs, patterns, and principles trumps memorizing commands.

Corporate IT Trainings


In an AI-augmented world, your competitive advantage lies in teams who can architect solutions, not just write code. We help companies build this strategic capability by training employees and partners in the skills that truly differentiate: system design, architectural decision-making, cloud strategy, scalability thinking, and technical leadership.


Our verified training programs cover Java/Spring, DevOps/Cloud (Azure/AWS/GCP), Databases/SQL, System Design, and beyond—each designed to elevate your team from implementers to architects. We focus on developing the judgment, design thinking, and strategic technical skills that AI cannot replace.


Whether you're a multinational corporation transforming your engineering culture or a growing business building your technical foundation, we deliver tailored learning solutions that prepare your teams for the realities of modern development.

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, as I regularly travel across the EU to deliver in-person corporate training.

When you learn with CodeHunters, you're learning directly from someone who lives and breathes this stuff, someone who's made the mistakes, solved the problems, and is genuinely excited to help you master what matters most in modern software development.
