Mannatpreet Singh Khurana
I build reliable backend systems and cloud infrastructure — Spring Boot microservices, event-driven pipelines on AWS, and full-stack products with TypeScript. Currently shipping production systems at Stikbook INC.
Featured projects
Systems I designed and shipped end-to-end — from architecture to production.
CodeQuest
Competitive programming platform with a scalable code execution pipeline — API → Redis queue → worker → Judge0 → PostgreSQL — for reliable concurrent submissions and real-time result streaming.
Paybuddy
Wallet application with bank on-ramp flows via a mock bank server and webhook-based transaction confirmation, plus a merchant portal for payments, inventory, and sales monitoring.
Stylera
Wardrobe recommendation platform with a React Native frontend and a polyglot microservices backend — Java services for user and wardrobe data, a Python ML service for outfit recommendations.
Recent writing
Notes on backend systems, cloud infrastructure, and lessons from production.
