Sai Tarun Reddy Lankireddy

AI Software Engineer

I build Python backends and LLM systems. Right now I'm launching Nita, an AI wellness app I built on my own. Before that, I built RAG and agent workflows used by 500+ people at Molina Healthcare.

I care about AI you can check: answers grounded in real data, and evaluations that gate every release.

Open to backend and AI engineering roles

Work

Start with Nita, my strongest end-to-end product. Clinical RAG at Molina is my largest-scale production work.

Solo-built from first commit to App Store approval. A pure-Python stats engine computes every number, and Claude is only allowed to explain them. Launching October 2026.

Small working pieces of things I've shipped. Play with them.

Retrieval

Move the query. The nearest chunks get pulled in, the core of the RAG platform at Molina.View source

Ready

df.groupby("Region")["revenue"].sum()

Self-healing code

Press Run. The first try fails, the error goes back, and the model repairs it, like the Data Copilot.View source

Consent gate

Flip consent. Every AI endpoint in Nita checks it on the server, not just on screen.View source

Not enough data yet, so Nita says nothing about this.

Pattern unlock

Log days. Nita stays quiet until there's enough data to say something true.View source
