Developed a decentralized application (dApp) on the Solana blockchain to estimate transaction fees based on parameters like operation complexity, additional accounts, and data size. Implemented the smart contract using Rust and the Anchor framework, ensuring efficient and secure on-chain computations. Designed and built a responsive frontend with React and Tailwind CSS v4, leveraging its CSS-first configuration for streamlined styling. Integrated Solana wallet adapters to facilitate seamless user interactions with the blockchain.
Built a fully on-chain DeFi Options Vault (DOV) on Solana using Rust and Anchor to automate covered call and put selling strategies. Designed smart contracts to handle user deposits, option auctions, and yield settlement. Integrated SPL tokens, oracles, and Solana clock for time-based vault cycles. Optimized for low compute and high throughput on Solana’s parallel runtime.
Built a Dead Man’s Switch on the Internet Computer Protocol (ICP) using Rust—a smart contract that triggers an automated action if the user becomes inactive (e.g., fails to check in periodically). This project explored ICP’s decentralized capabilities, Rust’s efficiency in smart contracts, and real-world use cases for accountability systems.
Developed a full-stack decentralized identity verification system using Solana smart contracts for on-chain storage of identity hashes, integrated Zero-Knowledge Proofs for privacy-preserving validation, and implemented JWT-based authentication for secure access control. The frontend was built with Next.js and TypeScript, enabling seamless user interaction for identity registration and verification, while the backend (Node.js + Express + MongoDB) handled user data and blockchain communication.
