About — Alvin Bellero

background

Hello World! I'm Alvin — devoted husband, proud father, and passionate software developer with a knack for building impactful Web applications.

With 14+ years of full-lifecycle software development experience, I specialize in modern, scalable front-end architecture using Angular, React, and Next.js. I'm known for designing reusable component libraries, implementing high-performance UIs, and translating complex business requirements into elegant, maintainable solutions.

I'm especially excited about agentic AI — building systems where AI doesn't just assist but autonomously reasons, plans, and executes multi-step tasks. From coding agents to tool-using LLMs, I believe this is where software development fundamentally changes.
