Rosa Reyes
Software Engineer.
I build products end-to-end: interfaces, systems, and everything in between. Four years at Stylib, a CS degree at UC3M.
A bit about who I am.
I'm Rosa, a software engineer based in Madrid, with a really loud keyboard and a deep cup of coffee. I'm into the engineering side of things: how systems fit together, why they break, and what makes them feel good to use.
I got into programming as a kid because I wanted more out of The Sims. Cracking games turned into fixing missing DLLs and mystery Windows errors for everyone I knew, which turned into torrenting software, which turned into taking online courses and building websites for anyone who'd let me. I was self-taught before I even knew that was a thing.
I started university in Venezuela, ended up finishing my Computer Science and Engineering degree at UC3M in Madrid and stayed. Off-screen: bouldering when my hands let me, concerts whenever I can, video games, and a stack of books I'm definitely going to finish this year.
Where I’ve done the work.
Five years. Product work, freelance, and a bit of everything. Click to expand.
Things I’ve made, and care about.
Semantic Search Engine
My CS bachelor thesis, built in collaboration with Stylib. A multi AI agent system that turns natural language into structured product searches using an Entity-Filter-Validator pipeline. Makes finding architectural products actually work.
Stylib Visual Search Widget
Semantic product search widgets for Stylib. Users upload a photo of what they need and get matched to real architectural products. Built the full frontend integration.
Stylib Product Showcase
Frontend architecture for an interactive product showcase built around design specifications. Focused on performance and making complex product data feel effortless to browse.
Stylib HUB
Product catalog management dashboard for architectural material suppliers. A centralised hub to consolidate, manage, and distribute product data, images, and documents across channels — keeping every catalog accurate and up to date.
Secure Messaging App
End-to-end encrypted chat built for a cryptography course. AES-GCM for messages, RSA for key exchange, digital signatures, and a full PKI for user registration and cert management.
Rosa Reyes Web
This site, built and rebuilt as a design and engineering playground. Currently on its third version.

Say hello.
Open to full-time roles and freelance. If you want to talk software or work, email is the best way to reach me. I read everything and reply to most things.
