Tony Huynh

Fractional AI Builder

Summary

I help startups take new products from idea to launch. I joined IDMe at seed as part of the founding team and stayed through Series B, going from senior engineer to VP of Engineering and then VP of Product. Since 2017, through 29FX, I have worked with small founding teams to decide what to build and then built the first version, and most of that work is now AI.

Experience

29FX

Sep 2017 – Present

Principal Consultant

Founded in 2010. Open to fractional and 1099 contract work in AI and engineering.

Fractional AI builder for startups and product teams. I work with founders from the first idea: deciding what to build, designing the architecture, and shipping the first version.

  • Build agents, voice and vision pipelines, MCP integrations, and consent steps that keep a person in the loop, with local models when the cloud is the wrong fit.
  • GiveCampus: co-built GC Events (Rails, Hotwire, Tailwind, Sidekiq, Stripe, Heroku).
  • Hungry: rebuilt the core Rails API to handle expansion and heavier traffic.
  • ISEP Study Abroad: led three engineers through a major CMS redesign.
  • fTLD Registry Services (2017–2025): built the first domain-monitoring system for .Bank and .Insurance.
  • PrePlanLive (2018): built a first-responder incident MVP on my own (Twilio, Matterport).
  • BaseRent: built a rental management MVP with credit and background-check integrations.
