Experience
Frontend Developer
Azuro 2022 - 2026
Azuro is a decentralized protocol and infrastructure layer for prediction markets. Joined at the founding stage and helped scale the product to 40+ live applications with $530M+ in processed volume, and ~$500K in weekly transaction volume. • Authored and maintained @azuro-org/sdk and @azuro-org/toolkit from 0→1, the primary React/TypeScript integration libraries used by 5-10 operator frontends to build on the Azuro Protocol. Shipped multiple major versions covering data hooks, write hooks, real-time hooks, and utility functions for market aggregation and smart contract abstraction. • Wrote the full developer documentation for the SDK and Toolkit at gem.azuro.org/hub, enabling external operators to integrate independently without direct support. • Architected a migration from blockchain contract events to WebSocket-based odds delivery in the SDK and Toolkit, solving a core reliability issue where on-chain event polling caused stale and delayed updates under high-frequency market conditions - eliminating odds lag complaints from operators across all integrated frontends. • Owned end-to-end implementation of the freebets/bonuses, cashout, and live betting systems in the SDK and Toolkit, enabling any operator frontend to integrate these features out of the box using the library rather than building custom solutions. • Built the Liquidity and AZUR Staking interfaces for the Azuro Portal (azuro.org/app), including complex DeFi flows for liquidity provision, staking positions, and reward management - interacting directly with protocol smart contracts. • Delivered complex financial and market-facing interfaces including real-time odds dashboards, live betting UIs, payment and token flows, affiliate revenue tracking panels, and operator-facing admin tools. Integrated smart contracts and wallet connectivity across multiple EVM chains using Next.js, TypeScript, and GraphQL (Apollo), focused on real-time data accuracy and cross-browser compatibility.
