About

What I do

I bridge the gap between complex enterprise operations and 0-to-1 software development. My background combines executive-level SaaS leadership with hands-on engineering, but recently, I've been running a personal AI lab just to explore the massive new green fields opening up. Tracking the approach of the singularity through local-first LLMs and agentic workflows is wild, but I maintain a strict real-world sensibility when evaluating these tools. Honestly, what a time to be alive.

I pair this experimental technical foundation with over a decade of grounded, operational reality. As the owner of a Brooklyn multifamily property and the manager of a complex, multi-stream investment portfolio, I know what it means to tie abstract technology directly to capital efficiency and P&L. I specialize in navigating ambiguous environments, aligning bleeding-edge architecture with operational realities, and deploying high-impact systems that solve actual business bottlenecks.
