Drawboard — Collaborative Online Whiteboard 🚀 I built and deployed Drawboard, a web-based whiteboard project, using a Turborepo monorepo architecture. The main goal of this project was to understand how modern full-stack applications are structured and how multiple applications and shared packages can be managed within a single repository. While building Drawboard, I explored monorepo architecture, workspace management, package organization, and the fundamentals of building maintainable frontend and backend systems. This project gave me practical experience with real-world codebase organization and helped me understand how to structure applications for easier development and scalability. Tech Stack: Turborepo, Next.js, TypeScript, Tailwind CSS, Vercel 🔗 Live Demo: https://drawboard-peach.vercel.app/ Always learning, building, and improving my engineering skills through hands-on projects.

Built a sealed-bid auction platform on the Stellar (Soroban) blockchain to eliminate bid sniping and create a fair, decentralized auction experience. The platform uses a commit-reveal mechanism, where bidders first submit a cryptographic hash of their bid during the commit phase and later reveal the actual bid amount once the bidding window closes. This ensures that no participant can view or react to competing bids before the reveal phase, preventing unfair last-minute bidding. The entire auction process is managed by Soroban smart contracts, which securely escrow bidder funds, verify revealed bids against their original commitments, automatically determine the highest valid bidder, refund unsuccessful participants, and transfer the winning bid to the seller. By removing intermediaries and automating settlement, the platform provides a trustless, transparent, and secure auction system. The application also features a modern web interface with Stellar wallet integration, allowing users to create auctions, place hidden bids, reveal bids, and track auction results through a seamless user experience. Tech Stack: Stellar Soroban, Rust, React/Next.js, TypeScript, Stellar SDK, Smart Contracts, Cryptographic Hashing, Blockchain.
