Alden Derf

Software Engineer · Full-Stack Developer

I build full-stack applications that solve real operational problems using modern web technologies and an AI-assisted engineering workflow.

AI-Assisted Workflow

ChatGPTCodexAntigravity

My workflow includes ChatGPT, Codex, and Antigravity for planning, implementation, debugging, and refactoring, while I own the requirements, architecture, business rules, testing, and final technical decisions.

I'm Alden Derf Fabro, an Ivatan software engineer and full-stack developer from Batanes, Philippines. My experience spans application support, hospital system development, technical instruction, and government operations.

I build full-stack applications with Next.js, React, TypeScript, Node.js, PostgreSQL, Supabase, Prisma, Laravel/PHP, and SQL Server.
