Hi, I'm Archie (張家齊)

Full-stack engineer & independent developer. I ship products from 0 to 1 — apps, websites, and everything in between.

What I Do

• iOS apps — 7 self-built apps on the App Store since 2015, 10 years running without a break. Find Drinks has 25K+ downloads.
• Web products — SEO tool sites, client projects (incl. government), and my own e-commerce brand, all on Cloudflare + Supabase.
• Ethereum standards — co-authored ERC-6672 (Multi-Redeemable NFTs), the 67th ERC adopted by the community.
