About Me

I'm a Software Development Engineer at Amazon, working on customer-facing backend systems.

Earlier, I worked on Prime Video live-events publishing and operator-facing tooling. I enjoy building things where scale, data correctness, and reliability matter—from event-driven workflows and search systems to media pipelines and developer tooling.

  • ⚙️ Backend and platform systems
  • 📨 Queues, workers, and event-driven architectures
  • 🔍 Reliability, operational tooling, and search
  • 🤖 LLM-assisted engineering workflows
  • 🧠 Compilers, runtimes, and systems programming
  • 🐧 Linux / Android enthusiast and hobbyist designer

The repositories here are public projects and experiments. My professional work is not published here.
