Front End Developer

Fullstack Developer

Most recently, I served as a Fullstack Developer at Quantum3 Labs (Singapore), where I led the frontend architecture and delivered end-to-end Web3 solutions on Starknet and Ethereum. I designed custom hook systems for wallet integration and transaction lifecycles, implemented multi-chain DeFi lending protocols, and built backend services with NestJS including real-time WebSocket APIs and transaction indexers. I also developed an internal TypeScript SDK (stormbit-sdk-ts) and improved system reliability through Playwright-based E2E testing.

Prior to that, at Live Channel Communications, I optimized large-scale React/Next.js applications, integrating Million.js to achieve a ~40% improvement in render performance, modernizing build tooling to reduce bundle size by ~15% and build time by ~20%, and enhancing SEO through SSR/SSG strategies for e-commerce platforms.

I bring strong command of TypeScript, React.js, Next.js, Node.js, and NestJS, as well as hands-on experience with GraphQL, WebSocket/Socket.IO, PostgreSQL, Prisma, and the broader Web3 ecosystem (Wagmi, Viem, Ethers.js, Starknet React). I take pride in establishing clean architectural patterns, writing maintainable code, and delivering features that directly improve user experience.

I am passionate about building products at the intersection of modern web development and emerging technologies, and I am excited about the opportunity to bring this energy to your team. I would welcome the chance to discuss how my background aligns with your goals.
