# César Alberca

> Freelance Frontend Architect. I help CTOs and engineering leaders turn fragile codebases into Scalable, Maintainable, and AI-Ready Frontend Systems. Less errors. Lower costs. Faster features. The outcome: effective, trustworthy, and autonomous teams — the kind that don't need me tomorrow. Because good architecture outlasts the architect.

## Why It Works

10+ years in Frontend Development. 5+ years in React, 4+ in Angular, 2+ in Vue. Production experience with DDD, Hexagonal Architecture, and Modular Design Systems. 30+ talks at international conferences. Book author published by Savvily. Codemotion Ambassador and committee member.

If your frontend is slowing down your roadmap, leaking bugs to production, or burning engineering hours on problems that should have been solved at the architecture level — a 30-minute call is usually enough to know if I can help.
