I earned $57,086 in Web3 audit contests, including first place in Cantina’s collar-core contest. For an XRP Ledger audit, I built an LLM workflow that backed findings with proof-of-concept tests, then reviewed each finding by hand and reported 1 High and 3 Medium.

I built a production backend for a clinic that syncs records from a legacy SaaS into PostgreSQL and sends patient reminders through Zalo. Staff can check system health and manage the calendar by chatting in ChatGPT through an MCP server. Earlier, I took over Stickman Master as core developer and shipped it to 5M+ installs.
