A little about me

I like figuring out how things work.

I’m a full stack engineer at ZirconTech, working remotely with distributed teams. I build web applications with React, Next.js, NestJS, and PostgreSQL, and take them to production on AWS.

My path started in mechatronics at IPN. That curiosity about how things work still shapes how I build: understand the whole system, pay attention to the details, and make something useful.

Lately, I’m exploring AI agents and bringing AI-assisted workflows into my everyday development with Claude Code and Cursor.

My everyday toolkit

TypeScript / React / Next.js / Node.js / NestJS / PostgreSQL / AWS / Prisma / Docker

Projects I’ve worked on.

Client work, side projects,
and a little experimentation.

Currently building

ACP AgentAn AI agent with a workspace of its own.

A web interface for an agent running in a remote microVM. Follow its work as it happens, pick up conversations, and preview or edit its generated artifacts in your browser.

  • Streaming conversations with visible tool activity and model selection.
  • WhatsApp integration: link your account and interact with the agent in selected groups, sharing conversation context with the web chat.
  • An artifacts workspace to edit and download code, documents, and HTML apps, with document and HTML previews and edits saved locally in your browser.
  • English and Spanish interfaces, plus a public demo with guest usage limits.
  • React Router
  • TypeScript
  • Node.js
  • ACP
  • WebSocket / SSE
Try the live demo

An ongoing project built on the Sistemas Agénticos workshop foundation, with goose as the AI agent.

Full stack / Marketplace

Repose

A marketplace for funeral services.

A funeral-services marketplace with three Next.js apps for families, providers, and administrators, backed by a shared NestJS API and PostgreSQL database.

Full stack engineer · Led AWS setup and management

5 engineers: 2 backend, 2 frontend, and me across the full stack.

Measured improvements

  • ~55% smallerSearch response payload
  • 382 → 12Database queries per search
  • 58 → 4React commits per ~2-second map drag
  • Next.js
  • NestJS
  • PostgreSQL
  • Stripe
  • AWS
My contribution
  • Worked across the three Next.js apps and NestJS API on provider search, arrangement flows, and Stripe payments.
  • Led AWS setup and management: Amplify for the frontends, Elastic Beanstalk for the API, RDS for PostgreSQL, and S3 for files.
  • Removed unused review and geocoding data from search responses and fixed N+1 database queries.
  • Reduced map-driven React updates and stabilized card props so surviving provider cards skipped re-renders during the measured drag.
