What I Do

// How I can help your team

Backend & APIs

REST and GraphQL APIs in PHP, TypeScript and Python. Session and token auth, pagination, filtering and clean JSON contracts.

Full-stack delivery

React + TypeScript front ends on top of solid backends — from database schema to responsive UI.

Legacy modernization

Migrating paper-based and legacy systems to modern, maintainable stacks without losing data.

Containers & deployment

Docker Compose stacks (nginx, PHP/Apache, MariaDB), Linux servers and reproducible environments.

Data & SQL

Schema design and query optimization on MySQL and MariaDB for real workloads.

WordPress & CMS

Custom plugins and themes for organizations that need to own their platform.

Featured Projects

// What I've built, concretely

PERSONAL PROJECT

Furmap

A collaborative map for a niche community

Problem Members of a niche community had no single place to find each other, discover local events or see who was nearby. Information was scattered across forums and social media.

Solution A mobile-first web app with an interactive map, community-verified organizations and an activity heatmap. The backend is split into microservices behind a GraphQL gateway; the front end is React + TypeScript running on Bun.

Results

API designed for concurrent traffic
Heatmap aggregates activity per area
Verification driven by community voting

Bun TypeScript React GraphQL PHP Docker MariaDB

PERSONAL PROJECT

SAE — Ecclesiastical Administrative System

Replacing paper records for a parish

Problem Parishes manage their records on paper. Documents degrade over time, information is lost, and looking up a single record is slow.

Solution A web platform that centralizes mass intentions, sacramental books and the parish calendar. REST API in PHP (Flight) with session auth and JSON responses; React + TypeScript front end; full Docker Compose deployment.

Results

5 sacramental books digitized
Mass intentions with date/time filters, search and pagination
Calendar with PDF export

REAL CLIENT

Semanario Mar Adentro

A news site the diocese owns

Problem The diocese's communications office depended on external providers and needed its own platform to publish weekly news.

Solution A custom WordPress theme and plugins for a news site, including a parish directory plugin, designed to be maintained by non-technical staff.

Results

Weekly publishing workflow
Parish directory covering the archdiocese
Responsive across devices

About

I'm a backend-focused full-stack engineer based in Acapulco, Mexico. I work mainly in PHP, TypeScript and Python, and I care about systems that keep working after launch: clear data models, predictable APIs and deployments that don't surprise anyone.

I work remotely with distributed teams. I'm open to remote-first roles and to collaborating with international teams.

What I look for in a team: real problems, honest engineering, and room to own a system end to end.
