About Mulhacén Labs

I'm Barry Faassen — a senior software engineer with over 25 years of professional experience. Mulhacén Labs is my independent digital product studio and AI consultancy, based in southern Spain.

I build production software that lasts. From complex backend systems and AI-powered automations to audio plugins and SaaS platforms, I bring the kind of engineering depth that comes from decades of real-world delivery — not tutorials and side projects.

My background

Before founding Mulhacén Labs, I spent years building mission-critical systems for organizations like Fugro, Shell, Rabobank, Deltares, and SITA.

That means geotechnical data platforms with 30+ years in production, financial rating engines processing complex models, 3D subsurface simulators for oil exploration, and airport equipment control software.

I bring that same standard of architecture, testing, and maintainability to every project — whether it's a EUR 500 AI audit or a EUR 50,000 platform build.

What I believe

• Clean architecture over quick hacks — systems should be maintainable years after the first commit

• Practical AI over hype — I integrate AI where it creates real value, not for the demo

• Owned, not rented — you get full source code, documentation, and deployment in your environment

• Honest scoping — fixed prices, clear deliverables, no surprises
