πŸ‘‹ Hi, I’m Siddharth Harsh Raj

πŸš€ Full-Stack GenAI Engineer β€” I build AI products that work in the field

Agents, RAG, and the full stack around them. My open-source and production work ships to 70+ organisations, and I own the whole loop: problem β†’ architecture β†’ CI/CD β†’ observability in production.

πŸ€– AI & Product Work

Avni Skills SDK β€” open-source agentic SDK Β· core engineer Β· adopted org-wide

  • A chat-driven generator wrapped in a Claude-Agent loop where every turn is a git commit and a validator runs after it.
  • Domain rules enforced as MCP tool-gates the agent must call β€” plus a hook that auto-reverts anything it does off-script.
  • Hard $5/session cost cap and a thrash-detector; 463 unit tests + a real-LLM eval harness that scores agent quality release-over-release.

Avni AI β€” production RAG + LangGraph Β· core engineer

  • Turns an NGO's programme spec into a deployable, field-ready mobile app β€” forms, validation rules, and logic generated by RAG + LangGraph, then human-reviewed.
  • Cuts implementation from 2–3 weeks to ~1 day; ships to 70+ orgs and 11M+ beneficiaries. Recognised as a Digital Public Good.

Avni Support Ops β€” agentic support workspace Β· sole author Β· private

  • Read-only / draft-only by construction: the AI drafts, a human decides β€” there is no write-DB connection anywhere in the workspace.
  • βˆ’60% ticket resolution time and +40% team efficiency, measured on real production tickets.

πŸ’» Full-Stack Projects

  • QuickPe β€” real-time fintech wallet Β· ACID-compliant transactions, RBAC, JWT auth, audit trails Β· scaled to 2,190+ concurrent users at ~391 ms, βˆ’70% DB load.
  • MeTube β€” video streaming platform Β· βˆ’92% API calls via caching & debouncing Β· real-time chat at <35 ms latency.
  • OpenCam β€” offline-first browser camera suite Β· MediaDevices API + IndexedDB, multi-device & cross-browser.
