James Edward Federbush

Full-Stack Product Engineer · Three Startups, Two Acquisitions

federbush@gmail.com · cv.edfed.me

Building software products since 2001, from first engineering hire under founding CTO at GLG through co-founding two acquired startups. Recent work is AI-native SaaS: multi-model orchestration, agentic workflows, and complete products shipped from concept to production. The through-line: building directly with the people using the product — from teams inside Fortune 500 companies to small field-service operators.

Experience

Independent

2018 – Present

Full-Stack Product Engineer

Independent from time to time, and exclusively since Docurated's acquisition — a sampling from across those stretches:

  • A private screening platform used by Academy members for Oscar voting, SAG Awards jury deliberations, and studio screenings at major festivals, including Sundance and Cannes
  • AI-native SaaS products, end-to-end. Recent work spans multi-modal lead qualification via voice agents and image analysis, conversational analytics, and full-stack agentic systems that orchestrate across APIs, models, and tools — from concept through deployed product with paying users
  • Product discovery and prototyping for Capital One — from novel digital credit products to an enterprise-wide SaaS platform
