About

I don't just build AI models — I build AI systems that actually work in production. As a GenAI and Agentic AI Engineer, I specialize in designing end-to-end intelligent systems — from multi-agent architectures and RAG pipelines to LLM evaluation frameworks and cost-optimized AI agents — that solve real business problems at scale. 🔧 What I'm building right now: At MySellerCentral, I architect Agentic AI systems powered by LangGraph and AWS Bedrock for e-commerce sellers, with short-term and long-term memory integration, so sellers get intelligent, context-aware automation — not just chatbots. I've also designed LLM evaluation pipelines that improve model selection accuracy for product image generation use cases, directly impacting business decisions on AI tooling. 📌 Key areas of expertise: → Agentic Systems & Multi-Agent Frameworks (LangGraph, LangChain, CrewAI) → Retrieval-Augmented Generation (RAG) using FAISS & ChromaDB → LLM Fine-tuning, Prompt Engineering & Benchmarking → Cloud Deployment on AWS (Bedrock, Lambda, S3) → NLP pipelines using Hugging Face Transformers & PyTorch → End-to-end ML pipelines from data ingestion to model serving → OpenAI API, embeddings, and cost-optimization strategies 🎓 Academic Background: I'm pursuing an M.Tech in Data Science at NIT Patna and a BS in Data Science at IIT Madras simultaneously — one of the few engineers combining rigorous research training with hands-on production GenAI experience. 💡 Beyond the code: As Placement Coordinator at the Training & Placement Cell, NIT Patna, I actively bridge the gap between academia and industry, connecting students to real opportunities. I understand what hiring teams actually look for — and I build toward that standard. ⚙️ Tech Stack: Python · SQL · LangChain · LangGraph · LlamaIndex · FAISS · ChromaDB · AWS Bedrock · OpenAI API · Hugging Face · TensorFlow · PyTorch · Streamlit · MongoDB · PostgreSQL · Power BI · Git 🔍 Open to roles in: AI Engineer | GenAI Engineer | LLM Engineer | Data Scientist If you're building AI-native products, scaling LLM applications, or looking for someone who can own the full GenAI stack — let's connect. 📧 shashi18102001@gmail.com | 📞 9534656882
