Software Engineer · Kalvium · Bengaluru

I build full-stack, AI-assisted systems that hold up in production.

Go, Python, Node.js, and a product-first mindset. From an LLM gateway routing 10,000+ calls a day across 65+ AI services to fault-tolerant onboarding, real-time platforms, and cloud data pipelines.

SDE-1 — Kalvium Private Limited

Own full-stack features, AI infrastructure, and data pipelines end to end in a distributed engineering team.

  • Built and run a LiteLLM gateway routing 10,000+ LLM calls per day across 65+ AI services.
  • Scaled a fault-tolerant, queue-driven onboarding engine to 1,000+ accounts at once across four services, including Keycloak provisioning, role assignment, email triggers, and suspension controls.
  • Own BigQuery datastream pipelines and dbt marts; introduced Cube as the semantic layer for analytics platform v2.
  • Deliver the Admissions Action Center and batch pipelines processing 10,000+ records per day, including production troubleshooting.
  • Review 15+ pull requests weekly, shaping architecture and code quality.

Open source

Alibaba open-code-review — Resumable full-file scans

Contributed PR #677 to the Go-based open-code-review project.

  • Implemented ocr scan --resume so interrupted repository scans continue from per-file checkpoints and skip already-reviewed files.
  • Reduced redundant SHA-256 hashing with per-run fingerprint caching; added scan-scope validation and tests following maintainer review.
