  • 🌍 Remote-first, async-ready, timezone-flexible

🚀 Flagship Project

⛓️ SuiGit — First Fully Decentralized Version Control Platform

Move (Sui)  TypeScript  Walrus Storage  Node.js CLI

✅ Full role-based access control
✅ Immutable commit history on Sui blockchain
✅ React frontend with wallet auth, diff views, PR workflows
✅ Four teams tried before me. None shipped it.

AI & LLMs

Claude OpenAI Gemini Z-Ai MCP LangChain

🤖 AI-Augmented Development

Not just using AI tools — orchestrating them.

Model Role in my stack
Claude Architecture review, code critique, complex reasoning
GPT Data parsing, structured output generation
Gemini Long-context analysis
Z-Ai Rapid prototyping, quick iterations

Built custom MCP server integrations connecting these models to local dev tools, external APIs, and CI pipelines for end-to-end automation. Consistently scope 2–3× more per sprint while owning all production decisions.
