Top SchoolHarkishen Singh is a Senior Software Engineer with eight years of experience building cloud-native data and observability platforms, currently driving live multi-terabyte database migration tooling at Tiger Data (Timescale). He helped create Promscale, a SQL-powered unified observability stack that enabled joining business data with Prometheus metrics and traces, and authored Prom-migrator to move terabytes of Prometheus data reliably. An active open-source contributor and two-time Google Summer of Code alumnus, he has made notable contributions to the flagship Prometheus project—improving PromQL, UI/React components and tsdb performance. Harkishen blends systems-level expertise (logical decoding, high availability, multi-tenancy) with frontend polish, having shipped both core database features and UX improvements. Based in Bengaluru, he focuses on minimizing production downtime for mission-critical workloads and delivering measurable performance gains (often 10x on key queries). Beyond code, he knits together tooling, docs and community support to make large-scale migrations and observability practical for real customers.
