Developed a smart-contract-based NFT minting and updating system for a March Madness-style tournament on SEI (an EVM-compatible chain), where users purchase tickets and submit bracket predictions. Developed the smart contracts in Solidity, deployed them on SEI Mainnet, and integrated seamlessly with a custom front end built in Next.js 15. Created a dynamic scoring mechanism that rewards users based on the accuracy of their bracket predictions. Integrated NFTs with Magic Eden Marketplace via its API for listing and selling, enabling secondary-market transactions. Ensured high security and performance through rigorous testing using Foundry.

Led the development of four major (production) projects with teams of 8 members, collaborating closely with the PM and Scrum Master using Agile methodologies to consistently achieve company goals on time. Conducted code reviews and provided constructive feedback to junior team members, fostering a culture of continuous improvement and high-quality code. Integrated existing Solana smart contracts into the frontend using Next.js, ensuring seamless interaction between blockchain functionalities and the user interface. Utilized WebSockets to enable real-time data processing, enhancing the platform's ability to track blockchain transactions on Ethereum and Solana. Optimized AWS costs by reducing RDS instance prices by 15% through reserved instances implementation and EC2 instance prices by 30% using Saving Plans. Developed over 18 modules/features using React and best coding practices, ensuring maintainability and scalability of the applications. Created a cutting-edge SaaS platform with AI productivity tools API, developing 30+ reusable React components using state management best practices with Redux Toolkit, enhancing development efficiency and code quality. Established end-to-end tests with 70% coverage using Playwright, ensuring the stability and reliability of the application. Integrated a MYSQL database, engineered over 20 intricate Discord command flows, and developed 5 cron-jobs for automating essential tasks. Enhanced newsletter site performance, increasing web speed by 40% and reducing AWS Amplify costs by 30%.

Improved user experience by 30% by creating a user dashboard based on designs provided in Figma. Collaborated on migrating users from Substack to AWS RDS, integrating Stripe and ActiveCampaign, saving the company 10% in commission fees. Boosted website performance by 70% by migrating from WordPress to NextJS.

Integrated over 5 microservices within two RESTful APIs using NestJS, TypeORM, and TypeScript; deployed via Docker and scaled with Kubernetes. Deployed PostgreSQL databases to AWS RDS and web clients using React and NextJS to AWS S3 and CloudFront. Reduced front-end bugs by 70%, improving application stability. Enhanced user reviews by 40% by collaborating with design and QA teams to refine UI and UX. Integrated Solidity smart contracts with Next.js for a play-to-earn game, ensuring seamless interaction between the blockchain and user interface. Developed and tested smart contracts for an RPG game using Solidity, implementing game mechanics and ensuring robust performance through comprehensive testing.
