Software that holds up in production.
I'm Luis Javier González Sánchez, Director of Engineering at LeadGenius. Thirteen years writing Python for real systems; today I lead an engineering team and ship two products of my own: FormaNativa and OpenTax.

What I'm on right now.
Three fronts that feed each other: the team, the products, and AI in production.
I lead engineering at LeadGenius
A B2B data platform that enriches companies and contacts at scale. Since 2019, from senior to lead and now director: architecture, priorities, and the team that makes it happen.
I ship products of my own
FormaNativa and OpenTax: complete products, from infrastructure to billing, built for the Mexican market.
I put language models to work
Agents, MCP servers and Claude-powered flows that solve real tasks: building sites, reviewing taxes, querying data. With tests, guardrails and observability.
Thirteen years on one line.
Each segment is a company. The amber shades are the three roles at LeadGenius.
Between 2013 and 2015 I worked at two places at once.

What I've built.
Complete products, not demos: infrastructure, billing, domains, support.
FormaNativa
forma-nativa.comA platform to build and host websites: describe your idea, let your AI assistant shape it via MCP, and publish it on your own domain. Forms, blog, catalog and billing included.
OpenTax
opentax.mxTax management for Mexican taxpayers: CFDI download and analysis, sync with the SAT (Mexico's tax authority), rule-based deductibility, supplier risk against the 69-B blacklist, and an MCP server to query it all from an AI assistant.
LeadGenius
leadgenius.comA B2B data platform: company and contact enrichment. As lead I built APIs, data pipelines and the integration that lets AI agents query the platform; today I run the team.
What I work with.
Python end to end, the web that exposes it, the cloud that runs it, and the models that make it more useful.
