Wasim Ahmad K.

AI Engineer specializing in RAG chatbots, LLM applications, AI agents, and computer vision — production systems that work in real environments, not just demos. I help businesses turn AI ideas into reliable, scalable products using LLMs (GPT, Llama, Mistral, Qwen), RAG pipelines, LangChain, and vector databases — turning messy PDFs, Notion, and databases into accurate, source-cited answers with low latency and near-zero hallucination. What I can build for you: • RAG chatbots & document AI — conversational search over PDFs, Notion, SQL/NoSQL with hybrid search, smart chunking, and verifiable citations • AI agents & automation — multi-agent workflows, tool calling, MCP integrations, API actions, and background pipelines that cut manual work • LLM fine-tuning & custom models — Llama, Mistral, Qwen fine-tuned on your data with LoRA/QLoRA/PEFT; local deployment and quantization • Computer vision — object detection, segmentation, OCR, and image processing • Backends & deployment — Python, FastAPI, Docker microservices, PostgreSQL, vector DBs (Pinecone, Weaviate, Chroma) on AWS/GCP with CI/CD Tech I work with: Python, FastAPI, LangChain, LlamaIndex, OpenAI / ChatGPT API, Hugging Face, PyTorch, TensorFlow, Pinecone, Weaviate, Chroma, PostgreSQL, Docker, AWS, GCP. How I work: Clean, tested code and clear communication. I design the full system — idea → architecture → development → deployment → scaling — so your AI ships and keeps running under real load. Backed by a PhD in Computer Science (AI/ML) and 15+ years of software engineering experience. Message me for a free 15-minute call to scope your project and map the fastest path to production.
