⚙️ LLM Engineering & Advanced RAG
As a senior LLM Engineer and AI Developer, I solve the "hallucination problem" — Schema-Guided Reasoning makes the LLM predictable: accuracy 66% → 91%.
Advanced LLM pipelines with Vector Databases (Pinecone, Weaviate, Milvus), terabyte-scale RAG on AWS Kendra + Bedrock: retrieval 15 min → 2–3 min.
Custom fine-tuning, prompt engineering, production LLM infrastructure with source attribution, RBAC and audit trails.
Detection pipelines designed to cut alert noise 200+/day → ~25, surfacing 4x more real cases (false positives 85% → 12%).

🛠️ FULL-STACK TECH STACK & DATA SCIENCE
As an AI Developer: Python, FastAPI, Docker, AWS, Asyncio.
As a Python Developer: LangChain, LlamaIndex, LangGraph, PyTorch.
As a Web Developer: frontend frameworks, responsive platforms, API integration.
As a Data Scientist: analytics pipelines, model evaluation, terabyte-scale warehouses from scratch.

❇️ WHAT YOU GET WITH EVERY PROJECT
Hire me as your AI Developer: production-ready, scalable, documented code with full CI/CD on AWS. As a professional Python Developer I keep your system robust; as a data scientist, your data gets maximum analytical precision. Whether it's an AI Chatbot Developer task for support or an AI Agent Developer workflow for outbound sales, you get one senior owner end to end.

As a web developer and agentic ai developer, I pair a data analyst's precision with python full stack developer agility — data-driven apps with trackable analytics.
