Cover image for Concordium — Supply Chain &
Concordium — Supply Chain & Testnet Infrastructure We delivered two blockchain projects for Concordium: a supply chain track-and-trace system and a testnet faucet. Track-and-trace: - Built a CIS-3 NFT smart contract (Rust) for product tracking. - Added sponsored transactions so users don’t need to hold tokens. - Implemented an indexer to track all on-chain movements in real time. - Shipped a full frontend and Docker-based infrastructure. Testnet faucet: - Developed a Next.js faucet with Cloudflare Turnstile bot protection. - Added per-address daily limits and balance checks via the explorer API. - Provided complete documentation for deployment and maintenance. Outcome: - Both systems production-ready and actively used. - 92 combined commits, clean architecture, ready-to-reuse patterns. This case shows our ability to ship end-to-end blockchain solutions—smart contracts, infrastructure, and UX—in one go.

Cover image for Create Stunning Custom Banners with This Easy Canva Alternative
Hello, I just built a simple tool similar to Canva that lets you create custom banners. I originally made it for personal use, but I decided to make it public in case it could be useful for others. Feel free to use it, and if you have any suggestions or feedback, I’d really appreciate it. https://ln-banner-generator.vercel.app/
