Hey, I'm Obed.

Obed Vargas

Software developer in Mexico City. By day, enterprise conversational AI. Off hours, independent tools for local businesses: digital stamp cards, menus, and WhatsApp agents that work at the counter.

Self-taught with a background in UX. I write TypeScript and Go, design the system, and share tools on GitHub when they can save someone an afternoon.

Rule one

If the taquero has to learn a new app, I already lost.

How I work
  1. 01

    Evidence over hunches

    Real user sessions and friction data before opinions.

  2. 02

    Ship fast, with a net

    Incremental releases, automated checks, zero counter downtime.

  3. 03

    Verifiable guardrails

    Deterministic boundaries, regression suites, and human takeover.

Experience

Where the hours go.
