The Architect & Leader.

I'm Angel Centeno. My journey in technology spans over 15 years—from front-end architecting iconic platforms for Broadway shows like Wicked and Hamilton to leading stealth startups as CTO.

My technical focus centres on edge-first architecture (Cloudflare Workers, D1, R2, KV), serverless AI systems (LLMs, RAG, custom agentic workflows), and modern full-stack frameworks (Astro 6, React, TypeScript, Tailwind CSS).

Rooted in Puerto Rican heritage and raised in high-pressure NYC agency culture, I bring bilingual fluency (English/Spanish) and 'resolví'o' (resourceful) leadership—bridging enterprise engineering standards with mission-driven digital transformation for Puerto Rico's future.
