EngemIA · Open to contract

I diagnose on the floor, build the system end to end, and own the metrics after launch. Hospitality, events and venue operations already run on what I shipped.

01Shipped work

Production systems, with the decisions behind them

The same three operations from the client site, written for a hiring manager: the problem, the decisions that shaped it, and what moved.

Problem→Decisions→Results01

Hotel del Principado

In production since Jul 2026

Independent hotel · Mexico City · External technology architect

Problem

Paper check-in re-typed into Excel, 63% of revenue arriving through OTAs that hide guest contacts, and a PMS and channel manager that talked to nothing else.

Decisions that shaped it

  1. 01Shipped digital check-in first: the most frequent, most visible pain, and it seeds the hotel's own guest database
  2. 02Used n8n as the reconciliation layer between the PMS and the channel manager instead of point-to-point scripts
  3. 03Measured the system's leads separately from what staff closed, so the ROI claim stays defensible

Measured results

Anti Tech Week

Ran live · Oct 2026

Mexico Tech Week 2026 · 5 days, 2 venues · Organizer and builder of the ops stack

Problem

A 5-day, 2-venue community program (workshops, demo days, sponsors) with no production team and no budget for event software.

Decisions that shaped it

  1. 01Built the ops platform as a template first, then instantiated it for this event
  2. 02Split door control (AFORO) from planning (EventoCore) so venue staff got one-screen, PIN-only tools
  3. 03Real-time voting app (Ship It Live) for the demo day instead of judging by hand

Casa Luma OS

MVP live for the venue's reopening

Creative members' hub · Mexico City · Tech partner

Problem

A floor audit surfaced three leaks: no visibility into bar vs. storage stock, cash that didn't reconcile, and member sign-up living in staff memory.

Decisions that shaped it

  1. 01Diagnosed on the floor (Gemba Walk) before writing a PRD with 5 core modules
  2. 02Prototyped the UI first to validate the architecture with staff before backend work
  3. 03Modeled a full ledger: orders, sales, stock by location, waste with photo evidence, shift and day close

05How I work

Operating principles

01

Ownership

I own the system end to end: diagnosis, build, deploy and the numbers afterwards.

02

Async by default

Written updates, recorded demos, decisions logged where the team can find them.

03

Documentation

I write the brief and the handoff, so the client can run the system without me.

04

Diagnose on the floor

I start where the work happens. I spent six months on a hotel front desk before automating one.

06Stack

Tools, grouped by what they do

Chosen per problem. Nothing here is on the list for decoration.
