Design that converts. Code that scales. Teams that grow.
I'm Fabián Miranda — Product Design Director and Frontend Architect. I lead design teams, build digital products for government and startups, and design systems that scale. From Colombia to the world.
Services
Product Leadership
I don't just design products — I lead the people who build them. Today I manage a 9-person team at OpiTech, where I turned an unstructured area into a machine with 160+ governance documents, 10 orchestrated AI agents, and a 24-initiative roadmap. If your product team needs structure to scale, I know how.
Frontend Architecture
Lighthouse 95+. Load time < 2s. Zero compromise. I build web applications with Angular and React that don't just look good — they're fast, accessible, and ready for millions of users. SSR, lazy loading, design tokens, modular components. The code I write today will still work in two years.
Design Systems
A button isn't a button until 9 designers use it the same way. I build complete design systems — from tokens and components to the documentation and governance processes that keep things from breaking as the team grows. I did it for OpiTech and the results speak: visual consistency across 4+ simultaneous projects.
AI Automation
I designed and deployed a framework of 10 AI agents that automates everything from brief validation to bidirectional OneDrive↔Notion sync at 7am every day. This isn't science fiction — it's what runs in production at OpiTech today. If your team loses hours on repetitive tasks, I can eliminate that.
Growth & Performance
Technical SEO that ranks. Metrics that predict. Conversion that grows. I implement growth strategies based on real data: hreflang for bilingual markets, JSON-LD for rich snippets, optimized Core Web Vitals, and dashboards showing what works and what doesn't. No smoke, just results.
E-commerce at Scale
One codebase. Multiple brands. Infinite possibilities. I build multi-brand e-commerce platforms where launching a new store means changing a config file — not starting from scratch. Checkout with Wompi, SSR for SEO, Firebase for real-time, and an admin panel anyone can use.
