Ahmet Bombaci - Staff Software Engineer and GenAI Consultant

Engineering Excellence Since 2006

I'm a Staff Software Engineer with over 15 years of experience building scalable backend systems and APIs across healthcare, travel, and financial technology. From processing 0M+ daily healthcare transactions at Collective Health to building 0K+ TPS reservation systems at Amadeus, I've consistently delivered high-impact solutions at scale.

Currently, I run AI46, a GenAI consultancy where I build RAG pipelines, evaluate LLM providers, and design human-in-the-loop workflows for compliance-critical applications. I'm passionate about the intersection of AI and regulated industries — where accuracy isn't optional.

What energizes me: complex data problems, clean API design, mentoring engineers, and building systems that actually matter.
