Sai Kumar

About

Backend engineer with healthcare and financial services experience (Humana, PNC) who owned production-grade, high-volume ingestion-to-API pipelines end-to-end in C#/.NET and SQL. Strong focus on data quality, handling out-of-order/partial upstream records, and improving reliability/observability via structured logging and telemetry, plus significant SQL performance tuning to reduce peak-load issues.

Key Strengths

• End-to-end ownership of production data pipelines (ingestion, validation, transformation, serving)
• Strong data quality and consistency controls (required fields, malformed payloads, duplicates, out-of-order/partial updates)
• Performance optimization in SQL (tuning, indexing, stored procedures) to reduce peak-load latency
• Production observability improvements (structured logging, telemetry, traceability of records end-to-end)
• API design for internal consumers with versioning/backward compatibility (v1/v2, additive changes)
• Developer usability focus (consistent responses, Swagger/OpenAPI docs, collaboration with frontend teams)
• Pragmatic delivery in ambiguous early-stage environments (incremental build-out, avoid over-engineering, stabilize post-launch)
