What I Build

I work best on products that need strong architecture, fast iteration, and unusually high technical range. In practice, that usually means:

  • AI product architecture and workflow automation that produce useful work, not demos
  • TypeScript, JavaScript, and Python systems
  • React, Angular, Node.js, and GraphQL applications
  • AWS, serverless infrastructure, and data-heavy backends
  • Developer experience, platform tooling, and internal products

Experience Snapshot

  • Html5Tetris: a browser Tetris build and an 8-bit side quest.

Writing

One lesson I learned the hard way: do not break your own article URLs. Canonical links matter.

How I Work

  • I prefer small teams with high trust and high standards.
  • I value elegant systems, direct communication, and execution over theater.
  • I care most about technology that improves quality of life, expands human capability, and keeps people meaningfully in the loop.

Working Together

If you're building an AI-first product, modernizing a platform, or need fractional technical leadership that can move from strategy to implementation, those are usually the problems I care most about. The cleanest path in is LinkedIn for direct outreach or Razroo for company work.

Background and personal notes

Houston, Chicago, Queens, Long Island, Manhattan, Jerusalem, Tel Aviv, London, San Francisco, Los Angeles, Silver Spring, Arlington, and Alexandria.

Living across that many places shaped how I build: move fast, stay adaptable, and do not confuse polish with substance.
