Harshit Singh

Software Engineer — Melbourne, Australia

Summary

I build and support production software, and have done so since 2017 — across enterprise ERP, retail loyalty, transport logistics and digital signage. My day-to-day toolkit is C#/.NET, Rust, TypeScript, PHP and SQL, with cloud and event-driven systems on top: Azure Blob Storage, NATS JetStream, PostgreSQL and CI/CD with GitHub Actions and Docker.

I am strongest where software meets operations: diagnosing production issues, automating deployments, writing tests and documentation, and turning business requirements into systems that stay maintainable.
