About Me

DATA
DRIVEN.

I'm Ashish Siwach, a Data Analyst with an MSc Business Analytics (Distinction) from the University of Exeter. I specialise in turning raw, complex data into clear decisions — across machine learning, NLP, time-series forecasting, and marketing analytics.

Most recently as an AI & NLP Intern at the University of Exeter (NCIT), I built an end-to-end RAG pipeline for climate misinformation analysis and ran fine-tuning experiments on Gemma-2B, Mistral-7B, and Llama-8B using QLoRA.

I build systems that translate messy, complex data into decisions that matter — technically rigorous, clearly communicated.
