I'm a Senior Software Engineer with over 8 years of experience specializing in building scalable and high-performance applications. My recent work includes leading the development of a cross-chain launchpad for the $LUCKY meme coin, where I integrated third-party KYC verification and engineered backend logic for interactive games, resulting in a 900% increase in user engagement and the successful completion of a $70,000 token sale. I have a strong background in JavaScript, Node.js, and React/Next.js, with hands-on experience in smart contract integration and blockchain technologies.

• Led the development of a cross-chain launchpad and the $LUCKY meme coin on Base and Arbitrum chains, using Next.js for the front end and Node.js with Express.js for the back end, ensuring a scalable architecture for the DAO.
• Successfully facilitated a $70,000 token sale on the AstraDAO launchpad platform, demonstrating strong project management and execution capabilities.
• Integrated Purefi KYC third-party verification to provide trust and security during the token sale by identifying and verifying client identities, ensuring compliance and platform integrity.
• Collaborated closely with smart contract developers to ensure smooth integration between front-end applications and smart contracts, while engineering the backend logic for the Lucky Spin game that generates random numbers to ensure fair and transparent outcomes, boosting user engagement by 900%.
• Leveraged the Wagmi module for smart contract interaction and implemented Snowflake as the primary database solution to store and synchronize blockchain data, ensuring secure and real-time data management across multiple chains.
• Recommended and structured the GitHub repository following best practices, improving code organization and team collaboration, which led to faster feature development and easier maintenance.
• Developed secure and scalable APIs in Node.js, ensuring mobile responsiveness and cross-platform compatibility, while optimizing task management using the Linear tool for efficient daily planning and timely project completion.
