Rahul Singh
Applied AI/ML Engineer
Working on GenAI systems at Blinkit.
Before this, I shipped a VLM+OCR document pipeline that beat AWS Textract at 40% lower cost (Docxster), and built a RAG + ReAct agent stack that cut bid drafting from days to under an hour (LastDraft AI).
I write here about ML papers worth your time: the underrated, the load-bearing, the ones that don't trend.
