- 🔭 Now: going deep on Go and cloud infrastructure by rebuilding hard systems from scratch — a Terraform-style engine (light-tf), Git itself (mygit), containerized Go services (go-server) — and teaching what I learn through animated videos on X.
- 🛠 Before: DApp & Solidity Developer at Reactive Network (Apr 2025 – May 2026) — shipped ReacDEFI, the first production DApp on the network. $9K grant, press on CryptoSlate, Chainwire, Blockchain Magazine & BlockTelegraph.
- 🏆 6× hackathon winner (including 1st and 2nd place at the same international hackathon) · $13K+ in grants & bounties · 13+ technical deep-dives on Medium.
- ⚙️ I build my own tools: markdown-kindle (my reading pipeline — audiobook + AI ask), MacEditor (Swift video editor with Git-style versioning for video workspaces), chalkboard-animation-skill (Claude Code skill that animates my videos).
- 🧠 Operating principle: keep moving from crowded rooms to less crowded ones. Full-stack → Web3 → AI → Go/infra. I don't love a tech space — I love the tech, and the combinations.
- 📚 I learn hard systems by rebuilding them by hand, without AI — that's how the architecture and the language end up in my head instead of in my history tab.
