AI Engineer · Ruby on Rails Architect · Freelance based in Granada

Ismael Morales

I build software that scales.

Freelance AI Engineer and Ruby on Rails architect based in Granada. 10+ years designing robust systems, integrating artificial intelligence and turning complex problems into elegant solutions.

I'm Ismael Morales, a Senior Software Engineer specialised in Ruby on Rails and high-performance web architecture. Over the past decade I've led projects in EdTech, FinTech, LegalTech and real estate, designed REST and GraphQL APIs at scale and helped companies adopt artificial intelligence as a competitive advantage.


Independent consultant based in Granada and founder of urbanisti.co — a product that turns Spanish urban planning regulations into source-grounded, verifiable answers for architects and municipal technicians.


I care about engineering done well: clean code, solid tests, predictable delivery. I also enjoy the strategic side — understanding the business, prioritising what matters and aligning technology with real goals.
