Lead Smart Contract Engineer (project)

Delivered the core on‑chain codebase that defined how GTO could be transferred, locked, vested and redeemed by platform integrations. Implemented token standards, upgradeability hooks and security controls used during the public launch and subsequent platform migrations. Those technical choices directly determined which off‑chain activities (gifting, creator payouts, redemptions) produced on‑chain transfers and how those transfers were enforceable. Commissioned and supervised third‑party audits, responded to vulnerability reports and coordinated contract patches or migration plans when protocol fixes were required. The approach to vesting schedules, timelocks and owner privileges encoded in the contracts set the timetable for token unlocking and therefore influenced medium‑term supply pressure on exchanges. Worked with product and ops teams to expose developer APIs and integration points for wallets and partner platforms, shaping on‑ramps and off‑ramps between fiat/gift mechanics and token flows. The resulting architecture determined transaction costs, failure modes during mass redemptions and the resilience of token operations under load.
