Web and mobile apps, APIs and integrations, from the first sketch to the server they run on. I work across the frontend and the backend, and I connect what I build to the systems you already have. From Morelia, for clients anywhere.
01
It's the ERP I've worked with the most: custom modules in Python written with the ORM rather than around it, API integration with the rest of your tools, and functional setup of the apps your operation actually needs.
Sales
Purchase
Inventory
Accounting
Invoicing
Point of Sale
Employees
Payroll02
Apps for the work that doesn't happen at a desk: the sales floor, the street, a fingerprint reader wired to the machine. React Native for mobile, and Electron when the app has to talk to the hardware.
03
Portals, dashboards and internal tools for the work your team does every day. Frontend and backend in TypeScript, React or Next.js over APIs I write myself, meant to be understood by another developer two years from now.
04
I connect systems that don't talk to each other: your ERP, Mexican CFDI 4.0 e-invoicing stamped through a PAC, outside services and shop-floor hardware. Documented REST APIs that account for the errors, not only the happy path.
05
Code is worth nothing until it runs. Deployment on Linux, a VPS or AWS, containers, backups and automatic releases from Git. Afterwards I stay for the maintenance and to train whoever is going to use it.
Systems that are running in production today.

I built the API that integrates the portal with Odoo, and worked on both the frontend and the backend. Issuing, PAC stamping and invoice lookup from a single interface, without leaving the ERP.

Local pharmacy, freelance project
A complete system for sales, payment records and stock validation, with TypeScript end to end. I deployed it and I run it on a Linux VPS with remote access and continuous availability.

Soluciones en Ingeniería Tekniu
A desktop application connected to Odoo that verifies a wholesale customer's identity with a fingerprint reader before closing the sale, to cut fraud at the counter.

Soluciones en Ingeniería Tekniu
A mobile app integrated with the ERP over REST so the staff can look up and record information from the sales floor, without walking back to a computer.

Instituto Tecnológico de Morelia
Modules for the school management platform that turned a manual procedure — papers going back and forth between offices — into a digital flow students follow from their own account.
I'm a computer systems engineer from Instituto Tecnológico de Morelia. Since January 2025 I've worked at Soluciones en Ingeniería Tekniu, where I run the software department.
I grew up and studied in Morelia, a city of pink quarry stone that has been a UNESCO World Heritage Site since 1991. I bring it up because it explains how I work: here things are built to last centuries, with craft and without hurrying to show off. I'd rather have a module that survives the next Odoo upgrade than a pretty demo that breaks in production.
What I do best is sit down with the person who is going to use the system, understand how they actually work, and turn that into releases that are useful from the first week. Most projects that go wrong don't fail because of the code; they fail because nobody asked enough questions at the start.
I work on central Mexico hours with clients anywhere, and I take on projects of my own when someone needs a person who understands the business and the code in the same conversation.
I play the piano, I listen to music all day, and I write code for the fun of it, not only for work.
