Contributed to backend and frontend of safety-critical rail automation systems within an Enterprise Agile environment. Designed hybrid cloud infrastructure (AWS & Serverless) with Lambda and API Gateway; implemented Cognito for authentication, DynamoDB for high-performance data access, and Terraform for infrastructure as code. Worked on game-engine integration (Unity & C#) and network optimizations (Client-Side Prediction, Server Reconciliation, Lag Compensation). Built CI/CD pipelines using GitHub Actions to deploy Next.js web platforms to Vercel and serverless functions to AWS.
