About

Pragmatic early adopter & problem solver. I design multi-agent AI systems with planning & memory, then coach teams to run them smoothly. I scaled a distributed team of 50 devs to build and maintain a GraphQL platform. My journey began in assembly - coding on Zilog Z80, Motorola 68k and DSP 56k taught me to optimize at the hardware level. I then moved up to enterprise Java/JEE backends and built full-stack apps with Angular, React, Ionic, Node.js and TypeScript. With 20+ years of software experience, Iโ€™ve led ML/AI integrations, mobile and web projects across real estate, fintech, education, medical (drug and pharma software), travel and media โ€“ always following agile and DevOps practices. Today I focus on specification-driven and agentic higher-level abstractions - crafting frameworks where autonomous agents work together toward human goals. As an AI Holistic Advocate I mentor colleagues, champion ethical design and connect technology with real-world impact. Letโ€™s connect if youโ€™re interested in building responsible, scalable AI solutions that evolve from assembly all the way up to autonomous systems. NOTE I donโ€™t respond to generic recruitment requests that arenโ€™t a good fit for my specific expertise.
