# Shidhin Varghese Philip

**Headline:** Professional profile
**Location:** Chicago, IL, USA

## About

Shidhin Varghese Philip is a founding AI engineer who has worked on a lean two\-person team, owning the end\-to\-end workflow for an AI product, including ground\-truth data curation\. Shidhin’s strengths include retrieval\-augmented generation \(RAG\) systems, vector databases, agent\-based retrieval, prompt engineering, and evaluation of machine\-learning systems\. As a founding engineer, Shidhin built a RAG chatbot using Pinecone, web scraping, and a validation layer designed to protect users from hallucinated web data\. Shidhin also created comprehensive evaluation datasets and uses F1 scores to assess system quality\. A key validation system achieved a 95% F1 score for preventing hallucinations\. The work delivered substantial efficiency improvements, reducing research processes that previously took months to as little as minutes\. Shidhin is experienced in building reliable retrieval workflows that combine curated ground truth, validation, and safety\-focused prompting to build user trust in AI\-generated results\.
