Developed a real‑time crew scheduling analytics tool using Node.js + PostgreSQL, replacing manual PDF workflows. Handled API rate limits and auth for multiple carrier endpoints. Migrated legacy C# backend services to Python microservices, improving deployment velocity by 40%. Designed responsive dashboards with Next.js and TypeScript, implementing polling fallbacks for near‑real‑time train tracking. Integrated LLM APIs (DeepSeek) to automatically flag schedule conflicts and surface actionable insights from raw shift data. Managed full deployment lifecycle on Azure without a dedicated DevOps resource. Built a cross‑chain NFT bridge prototype using LayerZero (Solidity + off‑chain relayer) between BSC and Polygon. Developed a Python bot that monitors mempool for specific transaction patterns and triggers automated claim processes for a DeFi loyalty program.
