About me
Hi, I'm Tayyab. I build production AI systems/Agents end-to-end — architecture to deployment.
Years shipping reliability-critical work across HR, healthcare, fintech, and ecommerce. Now fully focused on applied AI: local LLMs, LoRA fine-tuning, hybrid RAG, plus the production layer most freelancers skip — eval, audit logs, red-teaming, Docker, CI.
Strong QA background. I write tests as I build, so what you receive works on day one.
