United States

Architected and deployed the complete real-time backend oracle and indexing layer for a high-frequency livestream prediction market (60s settlements) using Convex and TypeScript, enabling sub-second state sync and WebSocket broadcasts across dynamic LMSR-priced markets. Designed and implemented a production TypeScript SDK (PredictionMarketManager + LMSR math helpers, PDA derivation, resolution tickets) that unified complex on-chain interactions, reducing frontend integration time by 40%. Engineered a stateless on-chain design combined with off-chain event-sourced resolution model (mathematical pool/payout accounting + PDA rent recovery); refactored state to lightweight event logging, cutting operational costs by 73%. Owned end-to-end: Anchor/Rust smart contract (LMSR pricing, custom math, 27+ tests, events), Express + Convex backend (oracle signing, indexing, real-time WS), SDK, scripts, and devnet deployments.

Remote

Architected and implemented an automated non-custodial LST yield splitting protocol on EVM with Solidity/Foundry contracts: PrincipleVault for principal tracking at lock-time value, epoch-based harvesting triggered by Chainlink Automation + Chronicle oracles, DEX swaps of yield to USDC rewards into RewardVault, and proportional claims. Built supporting services, oracle adapter, full transaction flows, and React frontend for deposit, rewards dashboard, and principal unlock; deployed and tested complete system end-to-end.

Developed production backend and integration logic for the Staker multi-pool Solana staking platform (supporting liquid staking and native pools) with universal modals, hooks, on-chain data aggregation, and wallet integrations (Reown AppKit) for reliable user staking and reward features. Won 1st Prize at Solana Cypherpunk Dublin Sidetrack; managed GCP infrastructure deployments and production services for the staking frontend/backend and reward-related functionality.
