What I'm looking for

I seek remote roles building blockchain and full-stack products, focusing on smart contracts, multi-chain deployments, performant frontends, and collaborative, product-driven teams.

I am a certified web and blockchain engineer with over seven years of experience building full-stack web applications and decentralized projects for global and national clients.

I began my professional career at ServiceNow Singapore, working as a full-stack developer on large projects where I advanced to a Certified Web and Blockchain Engineer role and honed skills in React, Node, Ruby on Rails, TypeScript and database integrations.

As a senior developer and smart contract engineer, I led end-to-end blockchain initiatives including DApps, DeFi, CEX/DEX integrations, NFT marketplaces, and a multi-chain lottery project built with Solidity, Rust and Substrate, deployed across BSC, Solana, Avalanche, Optimism, Arbitrum, Tron and Polygon.

I focus on performance improvements, secure smart contract design, multi-network deployment, and delivering responsive, production-ready frontends while collaborating on product strategy and KYC/payment integrations.
