Hire the Best Windows Freelancers
in Mexico

I build custom systems, modernise legacy software, and set up automation that actually works. I am a senior PHP and SaaS architect based in Mexico, offering full US business-hour coverage. Over the last 30 years, I have engineered high-pressure systems across the UK, USA, Canada, and Mexico. My career began at the UK Met Office, building platforms for global climate data and government briefings—environments where uptime and accuracy were non-negotiable. Since then, I have designed infrastructure for finance, logistics, and commerce. Lately, I’ve been focused on custom SaaS platforms, API integrations, and multi-agent AI pipelines. My latest project is CarbonVerified, an AI system that automates Net Zero compliance for UK small businesses. I operate as a solo engineer. I handle the scoping, I write the code, and I manage the delivery. No outsourcing, no agencies, and no unnecessary layers. If you need something built properly, let’s talk.
