About vinay

AI/ML Engineer with 5+ years of experience building production machine learning systems across financial services and healthcare. Currently at Capital One, where I fine-tune large language models and build RAG architectures that power customer service automation and fraud detection. Previously at Apollo Hospitals, where I developed computer vision models for medical imaging diagnostics that processed thousands of patient scans daily. My work spans LLM fine-tuning using LoRA and QLoRA, building retrieval-augmented generation pipelines, optimizing model inference for low-latency serving, and deploying end-to-end MLOps workflows on AWS. I've taken models from experimentation to production at scale, working closely with cross-functional teams including software engineers, radiologists, and business stakeholders. I care deeply about building AI that's not just accurate but explainable, scalable, and responsible. Whether it's reducing fraud losses in financial services or helping clinicians catch diseases earlier, I'm driven by the impact these systems create for real users. Always open to connecting with folks working on LLMs, medical AI, or MLOps.

Experience

Ai / Ml Engineer

Current

Capital One

Fine-tuned open-source LLMs (Llama 3, Mistral) on proprietary financial data using LoRA/QLoRA, achieving 92% intent classification accuracy for customer service automation. Built RAG pipelines with LangChain and Pinecone to enable real-time querying across 50,000+ internal documents, cutting agent lookup time by 40%. Optimized inference through quantization and batching strategies, reducing p99 latency from 450ms to 320ms at 5,000+ daily requests. Designed A/B testing frameworks that improved fraud detection recall by 18% without increasing false positives. Implemented automated retraining pipelines and production monitoring to maintain model accuracy against evolving fraud patterns.
