How It Works
Three steps. No meetings about meetings.
Discovery Call
30 minutes. Tell me the problem. I'll tell you if I can help — and what it'll take.
Proposal & Plan
Clear scope, fixed price or hourly rate, timeline. No surprises. You approve before any work starts.
Build & Deliver
I build it. You review it. We iterate until it's right. Then I hand it over with documentation and support.
I'm Barry Faassen
A senior software engineer with 25 years of experience across scientific computing at Deltares, global geotechnical platforms at Fugro, and a decade of independent consulting.
I moved to the Alpujarras mountains in Spain to build Mulhacen Labs — a studio where deep engineering meets practical AI.
I work directly with you. No project managers, no juniors, no hand-offs. When I say "I'll build it," I mean me.
