• Built a Web3 fitness training platform that gamifies NFT fighter training through real-world activities (Strava running, yoga, meditation), dynamically upgrading fighter attributes stored off-chain in SQLite and generating OpenSea-compatible NFT metadata in real-time for 5,200+ fighters.
• Designed and implemented a microservice architecture with TypeScript/Express.js backend for training data and Strava API integration, Python/FastAPI AI trainer agent using LangGraph for workflow orchestration, and React/Next.js frontend with wallet connectivity via RainbowKit and wagmi.
• Built an AI-powered training recommendation system using LangGraph state machines, three ChromaDB vector databases (Action Recording, Training Analysis, Knowledge Base) for semantic search of user actions and patterns, and Ollama LLM integration for generating personalized coach responses with distinct personality modes (Dead/Butch) based on strict prompt engineering rules.
• Developed intelligent training analysis service that processes months of training history to identify undertrained fighter attributes, calculate consistency scores, analyze training patterns, and generate prioritized recommendations considering fighter training recency, Strava mileage availability, user goals, and consistency metrics.
• Optimized system performance with TTL-based in-memory caching (reducing database queries by ~70% and response times from ~100ms to ~10ms), SQLAlchemy connection pooling, parallel execution in LangGraph workflows, and real-time Strava API integration with activity filtering, daily sync limits, and monthly training cycle tracking.

• Developed minting of on-chain NFTs to represent documents stored on the TBConnect app related to tuberculosis research and analysis
• Upgraded overall application from Node.js 8 to Node.js 16 and React 16 to React 17 in 2023
• Upgraded dependencies and cleared all errors to improve overall performance
• Deployed the upgraded back-end to an AWS EC2 instance, the front-end to an AWS S3 bucket, and various APIs to Amazon API Gateway. As a result, the application is now fast, scalable with resizable compute capacity, highly secure, and very efficient
• Upgraded the chat and virtual meeting functionality from Twilio Video to the Zoom Video SDK to enable group meetings instead of one-to-one sessions
• Updated the visual aesthetic of the front end to enhance the overall user experience, making it more intuitive, engaging, and visually appealing

• Developed and deployed secure, scalable Ethereum-based smart contracts for the MintySwap platform, enabling NFT minting, token swaps, and DeFi interactions across multiple chains (ETH, BNB)
• Designed and implemented token upgrade mechanisms (V2 migration) with enhanced multisig wallet security and ownership of liquidity pools, maintaining low taxes while ensuring robust funding and liquidity management
• Integrated NFT marketplace functionalities, supporting creators and collectors with minting, trading, and managing digital assets on a decentralized platform
• Collaborated with front-end developers to provide seamless interaction between smart contracts and the user interface, ensuring real-time transaction tracking and optimized user experience
• Developed open APIs for third-party developers to interact with MintySwap smart contracts, promoting community collaboration and ecosystem growth
• Contributed to game-based blockchain applications, including NFT-based FPS and MMORPG games, enabling players to earn $MINTYS and $ETH through smart contract driven mechanics
• Conducted code audits and implemented best practices for security, gas optimization, and upgradeable contract architecture in a high-volume DeFi and NFT ecosystem

October 2020 - May 2022

• Developed and deployed new Solana programs to enhance the company’s blockchain ecosystem
• Collaborated with internal teams to design, build, and optimize Solana-based applications
• Led the development team, overseeing technical implementation and ensuring high-quality code delivery
• Directed end-to-end development of Solana smart contracts with Anchor, improving performance and reliability

• Migrated the back-end database from MySQL to MongoDB, significantly improving scalability, query performance, and handling of growing user and transaction volumes
• Designed and implemented a secure user authentication system, ensuring safe access and protection of sensitive customer information
• Integrated multiple payment gateways into a seamless payment processing system, enabling smooth and secure transactions for users
• Developed a real-time order tracking feature, enhancing customer engagement and satisfaction by allowing users to monitor their orders from preparation to delivery
• Ensured the platform was fully responsive and mobile-friendly, delivering a consistent and optimal user experience across desktops, tablets, and smartphones
• Built a scalable system architecture to support future expansion, additional features, and increased traffic demands
