Rogelio Lopez — AI Solutions Engineer

Solving real problems with software, across North America.

I'm an AI Solutions Engineer based in Mexico City. I hold a Licenciatura en Informática (Bachelor's in Information Technology) from Universidad Santander (2020–2023), along with certifications in AI engineering, full-stack development, and Python — and I’ve spent my career at the intersection of technology and business operations.

Over the past year, I solo-built a 93,000-line AI-powered SaaS platform for the Mexican restaurant market, designed the complete automation infrastructure for a Vancouver-based accommodation services company, and help businesses across industries implement AI — from RAG chatbots and automated marketing to full property management platforms.

I think in systems. I start with the business problem, design the architecture, build the solution, and measure the impact. Whether it’s a beauty distributor needing smarter customer service or a real estate developer needing a full SaaS — I deliver.
