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.
