About Mallika Sharma

I’m an AI/ML enthusiast turned Data Scientist at Barclays, where I wrangle LLMs, RAG pipelines, and build GenAI validation frameworks (yes, even AI models need a little reality check!).Along the way, I’ve built ETL workflows, automated security validations at Thales DIS, and optimized data systems at McAfee. As an M.Tech Gold Medalist in AI from NSUT, I’ve found my peace in research and published research papers on ML applications (turns out, predicting water quality is harder than predicting my weekend plans). Whether it’s fine-tuning a model or fine-tuning my next big idea, I thrive at the intersection of tech, curiosity, and impact.
