👨‍💻 About Me

I work at the intersection of LLM research and production ML — evaluating language models at scale, building reasoning systems, and shipping data products that reach millions of users.

  • 🔭  Researching multilingual LLM performance gaps and cross-lingual reasoning at ASU
  • 🏦  ex-Wells Fargo · Built GenAI QA systems and LLM evaluation frameworks on the Consumer GenAI team as Quant Analytics intern
  • 🏢  ex-Bajaj Finance · Shipped churn prediction, notification recommendation engine, and forecasting pipelines to production
  • 🎓  B.Tech CS @ VIT Vellore · Merit Scholarship, Top 10 rank
  • 🏆  Runner-up @ Voxel51 Visual AI Hackathon  ·  Finalist @ JPMorgan Code For Good

🚀 Featured Projects

Identifying LLM Performance Gaps Across Languages
Benchmarked OLMo-2-7B across ~100 languages and 10 datasets. Measured the correlation between pre-training token exposure and downstream accuracy, and tested English Chain-of-Thought as a cross-lingual reasoning bridge.

Self-Taught Reasoner for Mathematical Problem Solving
Implemented the STaR methodology on LLaMA 3.2-3B — iterative rationale refinement with hint-guided correction, outperforming both vanilla SFT and zero-shot CoT on GSM8K.
