Work experience

Software Engineer Intern at Clear, Jan 2026 - Present · 7 mos, Bengaluru, - Built an end-to-end email notification system for a GST reconciliation platform serving 1M+ Indian businesses using Spring WebFlux, Temporal workflows, MongoDB, and ClickHouse — eliminating manual status polling for enterprise users. - Resolved 3 critical production bugs in live GST workflows — a WebFlux codec misconfiguration, a ClickHouse type mismatch corrupting reconciliation filters, and a database routing bug traced across the full React to Spring microservice chain. - Optimized distributed Temporal workflow execution by pushing upstream validation in the reconciliation scheduler — eliminating unnecessary compute and preventing cascading failures for end users. - Extended a data enrichment pipeline (Python, DuckDB, Apache Arrow) to surface vendor data-freshness timestamps via ClickHouse — reducing reconciliation errors caused by stale vendor records.
