Hi, I'm Srivatsa Kamballa. I build the unglamorous half of software: the pipelines, the infrastructure, and the AI systems that have to keep working after the demo crowd goes home. Most of what I do lives in the gap between "it runs on my machine" and "it survives production at 3am."

• Currently building rag-redteam, mcp-snitch (session-level MCP attack detection), and minja-repro (reimplementing a no-code LLM-agent attack paper)
• Portfolio: srivatsa-kamballa.vercel.app
• MS Computer Science @ University of Illinois Chicago (GPA 3.88)
• Open to full-time Software, Platform / Infrastructure, and AI Engineering roles across the US
• Fun fact: I fix the bugs everyone else scrolled past in libraries you already import (10 merged PRs across Pydantic, LiteLLM, LlamaIndex, Haystack)

Those repos that look like forks of LiteLLM, LlamaIndex, Pydantic, and Haystack? That's where I actually fixed things. 10 merged, 4 open so far.

• LiteLLM (57k star): shipped time-based off-peak pricing in the cost engine, a backward-compatible feature on a core billing path. Caught an equal-ended window silently billing standard rates around the clock, and escalated the schema to maintainers rather than guess. PR #31725, +1,039/-25, merged.
• LiteLLM (57k star): fixed double-billing when cached and image tokens overlapped on multimodal requests. PR #37407, merged.
• LlamaIndex (51k star): silent data loss where all but the last chunk of a document was dropped on upsert. PR #22133, merged.
• Pydantic (28k star): a json_schema_extra dict was silently dropped, and schema generation could crash, when a callable followed it in an Annotated type. PR #13374, merged, maintainer-approved.
• LiteLLM (57k star): a masker leaked short secrets (8 chars or fewer) into logs and the admin UI. PR #30764, merged.
• Haystack (26k star): silenced noisy ERROR logs on empty inputs, plus authored the OpenSearch and Elasticsearch SQL-retriever docs. PR #11670, #11543, #11494, merged.

Plus the 10x embedding-pricing fix (#29693), a None-metadata crash fix in LlamaIndex (#22773), and 4 open PRs across LiteLLM, DSPy, and instructor (an SSRF fix that rejects IPv6 transition addresses embedding private IPv4).
