Hands-on engineering leader, taking on a small number of fractional and project engagements with US startups, in English or Spanish.
Mexico City · Miami · San Francisco
Pick where to start.
5-day audit + 10-day sprint
You built it with AI and it mostly works. I take it to production without a rewrite.
5 days
Flaky, slow or costly app? Team that keeps missing dates? I find where it breaks, the first fixes, and a 30-day plan your team runs without me.
2–3 days a week
Engineering leadership before you can hire it: planning, reviews, release gates and hiring, while I keep shipping code.
Pick my brain. I also take on:
Consulting is fixed-price, quoted after a 30-minute call. An audit or diagnostic is credited toward the sprint.
I led and built the iOS app and its backend, plus the dashboard and LLM pipeline that turns recordings into reports for sales teams and event organizers, with human review where it matters. The app records in-person sales meetings at trade shows and executive events.
I rearchitected the native macOS recorder for more efficient recording, added screen and internal-audio capture, and built its whole backend.
Async voice messages for remote teams, so a quick question doesn't need a meeting. I joined as a full-stack developer, then started, led and built two of its products on Mac and iOS.
I built Orion Startups' research center on venture capital and startups in Latin America, with its own contributors and review committee. Still online.
A career accelerator I founded and ran: members worked in "families" of four with weekly check-ins, and it helped people break into tech.
I designed and built the brand and website for a venture accelerator in Chihuahua, and worked with its startups.
The events platform for Tec de Monterrey's entrepreneurship programs. I started it at 17 and built it alone; it grew into a team and spread across Tec's campus network.
I was the engineering manager, so I started with my own job. If you don't kill your own product, someone else will. I rebuilt how our team worked around coding agents: specs first, automated checks, and agents that pass the same review as people. Here's what happened to our output.

Across AI, event technology, edtech and venture capital.
Since 2021 I've been at Backtrack, a US AI startup. I joined as a full-stack developer and grew into Head of Engineering, reporting to the CEO. Along the way I built and led the team behind its web, backend and native Apple apps.
I still build the product myself: LLM-backed systems with human review where it matters, native macOS and iOS apps in Swift, and the backend behind them. I'm a co-inventor on a pending US patent application for AI grading of event meetings (US 19/688,513).
Before that, as a teenager, I built software and helped with technical diligence on applicants at Orion Startups, a venture accelerator in Chihuahua. At 17 I started CarnetE for Tec de Monterrey.
Most of what I know about delivery I learned by getting it wrong first. I care about unglamorous things: specs before tickets, release checklists instead of heroics, hiring on real work instead of interview theater, and coding agents that have to pass the same review as people.
