Background

I've been building production software for over 12 years with startups and established companies: web applications, APIs, internal tools, and digital products. The through-line is reliable, measurable systems that solve real business problems.

Today my niche is AI agents for growth: SEO, AI visibility and RevOps. I work in TypeScript, Python, and Node.js on agentic workflows and intelligent automation: systems that research, decide, and act for the companies that deploy them.

I co-founded Prepa IN, an online platform that helps adults in Mexico finish high school in under four months, and Recupera, a bootstrapped app that helps salaried employees in Mexico recover their tax refund from the SAT. I also lead full-stack and agentic delivery at HUSL Digital.

Companies and work

Prepa IN

I co-founded Prepa IN in December 2019 as founding engineer. We built and launched the MVP from the ground up, validated product-market fit, and helped secure the company's first seed investment. I owned engineering end-to-end: architecture, product features, infrastructure, and the developer workflows that keep iteration fast.

The learning platform now supports 20,000+ active students across Mexico. Under the hood we have run large LearnDash/WordPress surfaces (including 6,000+ PDF lessons) and later moved the marketing site and blog from WordPress to Astro on Cloudflare in two working days, preserving every URL.

On that stack I built a fleet of Claude managed agents that research, write, review, and publish the Prepa IN blog. Prepa IN's Google Search Console impressions are roughly 20x where they started. That figure is impressions, not clicks. We also began internal testing of Aylin, Prepa IN's AI product for personalized learning.

In February 2026, 19 young people with motor disabilities graduated from high school through Prepa IN at a ceremony in the Senate of the Republic of Mexico in Mexico City, hosted by Senator Carolina Viggiano, in collaboration with FHADI México. My partners include Rodrigo Loeza (CEO of Prepa IN) and Arath Galván. That Senate portrait is the photo on this page.

Recupera

I co-founded Recupera in June 2026, a bootstrapped team building an app that helps salaried employees in Mexico recover their tax refund from the SAT in a simpler way. In August 2026 Recupera was accepted into AWS Activate, with cloud credits, technical guidance, and training to scale infrastructure.

Agency and earlier career

At HUSL Digital (since August 2018) I am a Senior Web & Agentic Engineer. Documented results include cutting end-to-end development and QA time for standard builds from roughly 50 hours to 8 (an 84% improvement) through AI-first workflows; a modular WordPress boilerplate that cut development time by 25% and bug rates by 37% across 15+ client engagements; and 20+ production plugins and custom platforms with 99.5% uptime.

Before that, at KTBO (acquired by Globant) I led front-end work on a Coca-Cola World Cup chatbot that processed 2M+ user interactions and exceeded campaign engagement targets by 35%, plus high-performance sites for Starbucks, Grupo Bimbo, and Mattel. At TERAN TBWA I built digital properties for brands including Nissan, McDonald's, BBVA Bancomer, and Volaris, and a seasonal e-commerce platform that cut client implementation costs by 90% while holding 99.9% uptime through peak holiday traffic.

I also founded and managed GDG IPN (Instituto Politécnico Nacional, Mexico City), which grew into one of the largest developer communities in Mexico.
