Her work centers on production LLM and agent systems, including orchestration, retrieval, retrieval-augmented generation, evaluation, and forward-deployed AI. Varsha works hands-on with Claude, OpenAI, and Gemini Flash APIs, and is strongest in taking AI systems from problem identification through design, internal testing, and independent production deployment. At Finta, Varsha identified and addressed an inference-cost challenge in two weeks, reducing cost per turn from $0.25 to $0.03—an 88% reduction—through prompt caching, deterministic tool ordering, and hybrid summarization using lower-cost models. She extensively tested the changes internally to preserve answer quality before rollout. Her technical toolkit includes LangGraph, Model Context Protocol, Python, TypeScript, pgvector, PostgreSQL, Supabase, Next.js, and Firebase. Varsha holds an M.S. in Computer Science with an AI & ML specialization from SUNY Buffalo, a B.Tech in Information Technology from Sri Sivasubramaniya Nadar College of Engineering in Chennai, and a Diploma in Data Science from IIT Madras. She has also authored two IEEE papers in computer vision and applied machine learning. ## Services - Software Infrastructure - Engineering - Software Design - LangGraph - Model Context Protocol \(MCP\) - Product Management - Product Leadership - Productization - Global Product Management - Product Planning - TypeScript - Firebase - pgvector - PostgreSQL - Retrieval-Augmented Generation \(RAG\) - Supabase - Next.js - Artificial Intelligence \(AI\) - Large Language Models \(LLM\) - Deployment - Deep Cleaning - Data Modeling - Transfer Learning - Convolutional Neural Networks \(CNN\) - vgg - Deep Foundations - Deep Neural Networks \(DNN\) - Recurrent Neural Networks \(RNN\) - Long Short-term Memory \(LSTM\) - Artificial Neural Networks ## Highlights - Serves as Founding AI Engineer at Finta, building the AI behind the product while supporting customers when technical issues need to be fixed. - Reduced inference cost by 88%, from $0.25 to $0.03 per turn. - Delivered the cost-optimization project from initial problem identification through production deployment in two weeks. - Used prompt caching, deterministic tool ordering, and hybrid summarization with cheaper models to reduce LLM inference cost. - Tested cost optimizations extensively internally before production rollout to ensure answer quality did not degrade. - Worked hands-on with Claude, OpenAI, and Gemini Flash APIs. - Independently owned the full lifecycle of an AI optimization project: identifying the problem, designing the solution, testing internally, and deploying to production. - Authored two IEEE papers in computer vision and applied machine learning. ## Experience - **Founding AI Engineer at Finta** (2025-01-01–present) ## Education - Master of Science, Computer Science, AI & ML Specialization — State University of New York at Buffalo (2026-01-01) - Bachelor of Technology, Information Technology — Sri Sivasubramaniya Nadar College of Engineering, Chennai (2024-01-01) - Diploma, Data Science — Indian Institute of Technology Madras (2023-01-01) ## FAQ ### What does Varsha do at Finta?
