About

I'm Mannatpreet Singh Khurana, a software engineer based in Ontario, Canada. I work at Stikbook INC, where I build and operate production backend systems — Spring Boot microservices, event-driven pipelines on AWS, and the observability that keeps them healthy. I care about clean architecture, fast iteration, and reliability under real usage.

Experience

Apr 2026 — Present

Software Engineer · Stikbook INC

  • Instrumented backend services with AWS CloudWatch alarms, dashboards, and Grafana; act as a first responder for production incidents — triaging alerts, debugging root causes across microservices, and shipping fixes to restore service health.
  • Built a geo-based offers feature end-to-end — users discover nearby offers on an interactive map and redeem via dynamically generated QR codes; architected the backend with Spring Boot and PostgreSQL with geospatial indexing for low-latency proximity queries.
  • Engineered an AI content moderation service in Python using multi-threading, GPT-4o for text/image moderation, and a Gemini audio model — filtering harmful content asynchronously without blocking user-facing upload flows.
