DAVID ARON · SENIOR SOFTWARE ENGINEER

I turn intelligence into interface.

I build production AI systems and the interfaces around them — from LLM integration at scale to the products people actually touch.

Experience

9 years building production software across diverse systems — AI, fintech, telecom, VR/AR.

Technologies

20+ currently in active use.
