Full Stack Engineer

I'm a Senior Software Engineer with 8+ years of experience specializing in scalable and high-performance applications across blockchain and web development. I recently led the development of a cross-chain launchpad for $LUCKY meme coin and $TMAI tokens, successfully raising $246,000 through a public token sale. My work included integrating third-party KYC verification, implementing staking & governance systems, and optimizing wallet connectivity, and on-chain swap with Privy Wallet & Li.Fi SDK. Additionally, I engineered backend logic for interactive games, achieving a 900% increase in user engagement.

I have a strong background in JavaScript, Node.js, React/Next.js, Prisma, and Supabase, with hands-on experience in smart contract integration, scalable API design, and database optimization. I am seeking an opportunity to lead innovative projects in blockchain or web development, leveraging my technical expertise to build impactful, high-performance solutions while collaborating with dynamic teams.
