About Me

My passion is helping organizations harness Generative AI and LLM-based solutions to create real business impact. I keep my hands on modern technology — building multi-agent systems and software factories, and using coding agents (Claude Code, Codex, GitHub Copilot Pro, Cursor) as my primary engineering interface.

4× CTO across four sectors — retail (RELEX Solutions, scaled to unicorn), healthcare (Hifian, founder), tax (Aibidia) and HR (TalentAdore). With 20+ years also spanning research, high-tech entrepreneurship, and senior leadership in energy, I bring both deep technical understanding and the ability to translate GenAI capabilities into scalable products. I have made 200+ recruitment decisions and led teams up to 150 people across 11 international locations.

I am currently finishing a PhD at Aalto University on Software Agents and Generative AI — defense and final publication expected Q3/2026 — with a Best Paper Award from PCSI 2025 and a 2nd Best Paper Award from CHIRA 2025. My leadership principles are built upon credibility, honesty, inspiration, empowerment, and true delegation.
