Most AI projects are impressive demos that collapse in production. I build the architectures that do not handle edge cases, eliminating hallucinations, and scaling reliably from day one. With 11 years of engineering experience, I specialize in the hard side of AI, rigorous model research, production grade system design, and full stack delivery. I do not just prompt models or wrap APIs. I build the data pipelines, memory structures, retrieval systems, and guardrails that make AI reliable enough for real business use. GENERATIVE AI & ADVANCED RAG Simple vector search is rarely enough. I engineer RAG systems that actually work in production: • Hybrid Search: combining semantic understanding with keyword precision for accurate, citation backed answers with near zero hallucinations • Semantic chunking and re ranking algorithms to ensure the model reads the right context before answering • Fine-tuning LLaMA 3, GPT, and Claude on proprietary data for domain-specific accuracy • Multi agent workflows using LangGraph and CrewAI agents that query SQL databases, browse the web, and trigger API workflows autonomously, with planning logic that keeps them on track • Production & cost optimization: caching layers and prompt compression strategies that reduce LLM API costs by 30 to 40% while improving speed • Tools: LangChain, LangGraph, CrewAI, OpenAI, Anthropic , Pinecone, Weaviate, ChromaDB, FAISS COMPUTER VISION & DEEP LEARNING For cases where off the shelf models fall short: • Custom CNNs and Vision Transformers for manufacturing defect detection, medical imaging, and document analysis • Real time object detection and tracking via YOLO, OpenCV, with WebSocket and Edge AI pipelines for live video streams and low latency market data • Model optimization: quantization, pruning, and performance tuning to run heavy models efficiently on edge devices or at cloud scale • Tools: PyTorch, TensorFlow, OpenCV, CUDA, Hugging Face Transformers, MediaPipe AI RESEARCH & MODEL EXPERIMENTATION When standard solutions don't give you the accuracy you need: • Rigorous model evaluation on real-world datasets with reproducible, well documented experiments • Performance benchmarking and ablation studies to identify what actually moves the needle • Turning research outcomes into clean, maintainable production code your team can scale confidently FULL STACK AI DELIVERY I bridge the gap where most AI engineers fail, connecting research grade backends to real user interfaces: • Frontend: Next.js (App Router), React, TypeScript, Tailwind CSS, D3.js instant load dashboards and data UIs • Backend: FastAPI, Django, Node.js robust Python APIs that handle data processing securely at scale • Real time systems: WebSockets and edge pipelines for live data without latency • DevOps: Docker, Kubernetes, AWS auto scaling infrastructure that survives traffic spikes CORE TECH STACK AI/ML: PyTorch · TensorFlow · Hugging Face · CUDA · Scikit learn · XGBoost GenAI: OpenAI · Anthropic Claude · LLaMA-3 · Mistral · Gemini Orchestration: LangChain · LangGraph · CrewAI · LlamaIndex Vector DBs: Pinecone · Weaviate · ChromaDB · FAISS Computer Vision: OpenCV · YOLO · MediaPipe · Albumentations Full Stack: Next.js · React · TypeScript · FastAPI · Django · Node.js DevOps: Docker · Kubernetes · AWS If you are tackling a hard problem that requires more than a plug and play solution, whether that is a production RAG system, a custom vision model, or a full AI powered SaaS, invite me to your job. Let's engineer something that actually works.
