Selected work

Vercel + GCP to Azure migration

A full production migration for a startup, delivered in one week as part of my Microsoft for Startups advisory work. The client stays anonymous.

  • One target architecture with acceptance gates per subsystem, then a single cutover, instead of carrying two platforms for months.
  • Agent-assisted execution with Claude Code and MCP, run with the startup's own engineers so they owned the result.

Stack: Azure / Claude Code / MCP / Azure Agent Dev Kit

  1. AOP Beacon

    Architecture and build for Amplification of Potential

    NFC beacons on event tables open an AI conversation prompt for the people sitting there.

    • The model gets four seconds. On a timeout, an error, or an empty reply, the table sees a prompt from a curated library instead, so the moment is never lost.
    • Requests carry only the stage, language, and chosen cards. Participant names never reach the model.
    • Bilingual, English and Spanish, across four conversation stages.

    Stack: NFC / OpenAI / Next.js / Supabase

  2. Presencia Studio

    Founder

    Websites, NFC business cards, QR menus, and a loyalty program for small businesses in Costa Rica.

    • Launched the MVP on Next.js 16, Supabase, and Vercel with a bilingual content system.

How I make architecture calls

The rules I bring to every system, whether I am advising a startup team or running my own product.

  1. Decide before the technology.

    Name the outcome, the constraints, and the cost of failure before choosing a model or a platform.

  2. Not everything should be an agent.

    A deterministic workflow is often the safer system. Autonomy has to earn its place.

  3. Evaluation before confidence.

    Latency, cost, and failure modes get measured and budgeted before anything is automated.

  4. Humans review what matters.

    Where a bad output has real consequences, a person stays in the loop by design.

  5. Leave the team owning it.

    Decisions, reasoning, and runbooks stay with the engineers who run the system after I leave.
