Implemented staking, unstaking, and reward-claim flows with Wagmi contract writes, ERC-20 allowance checks, receipt tracking, cache invalidation, and success/error states. Developed TanStack Query data layers with polling, query keys, DTO mapping, and cache refresh logic for live DOR rates, panelist submissions, consensus data, and rewards. Improved form correctness with React Hook Form, Zod, Viem unit parsing, wallet balance validation, vault capacity validation, staked-balance validation, and restricted-region confirmation flows.

Integrated wallet connectivity and smart contract interactions with Wagmi and Viem across Ethereum, Mantle, Arbitrum, Avalanche, Base, TAC, and Hyperliquid. Implemented normal and fast-lane redeem flows with allowance handling, transaction receipt tracking, and query invalidation for accurate redemption states. Integrated DeFi data sources including DeBank, Chainlink, Lido, Curve, Balancer, and Pharaoh to display balances, APR, TVL, exchange rates, fees, and Proof-of-Reserve breakdowns.
Gaia Foundation
Built a Web3 token claim and S2 airdrop platform that lets users connect wallets, check eligibility, review allocations, claim TREE tokens, stake rewards, and track transaction states. Implemented wallet-based API requests, Merkle proof validation, React Query caching, smart contract simulation, transaction submission, receipt tracking, and event log decoding. Developed claim-and-stake workflows for non-vested users, including panelist selection, vault staking inputs, post-claim refetching, and success-state persistence.

Added OpenGraph/Twitter metadata, Google Analytics, Microsoft Clarity, sitemap/robots support, commit SHA metadata, client error forwarding, and internal cache revalidation endpoints.
