About Me

I'm a full-stack developer passionate about creating elegant solutions to complex problems. With 6+ years of professional experience, I've successfully shipped production-grade applications across mobile and web platforms.

My expertise spans Flutter (iOS/Android), Next.js/React, and modern backend architectures including Firebase, Supabase, and AWS. I specialize in rapid product development using lean methodologies and AI-assisted workflows.

Currently working as a Software Engineer – Full Stack at God's Cleaning Crew (Toronto) and as a Freelance Flutter Developer for Azatecon (Singapore), where I built Aza Hub — a live Global HR & Payroll app on both stores — as the sole dedicated Flutter developer.
