What I'm looking for

I'm looking to build production-grade ML and GenAI products, especially RAG, LLM, document intelligence, and research automation systems, while growing in MLOps, scalable deployment, and end-to-end model development.

I've built RAG-based document question-answering systems and AI research agents, combining LangGraph workflows, semantic search, FastAPI, and LLM-generated answers with citations.

At Young Thames, I built Python and Playwright automation and multi-worker scraping pipelines that processed 4M+ trademark application records, with PDF extraction, checkpoint-based recovery, and Railway deployment. At Suvidha Foundation, I fine-tuned BART, PEGASUS, and T5 for multi-document summarization, achieving a ROUGE-L score of 27.63 with PEGASUS.

I'm focused on taking ML and GenAI systems from experimentation to production through scalable pipelines, vector search, Docker, Kubernetes, and MLOps. My work has also earned a Kaggle Notebook Expert badge and a top 6% global ranking in the NLP with Disaster Tweets competition.

Fine-tuned and benchmarked state-of-the-art transformer models (BART, PEGASUS, T5) for multi-document abstractive summarization on the CNN/DailyMail dataset using Hugging Face Transformers. Achieved a best ROUGE-L score of 27.63 with PEGASUS, demonstrating strong model optimization and evaluation skills.
