What I'm looking for

I'm looking to build and deploy production Generative AI products, especially LLM applications, RAG systems, agentic workflows, conversational AI, and scalable Python backend services.

At Thor Signia, I've designed and deployed production Generative AI applications, including LLM-powered chatbots and RAG pipelines that improved customer-service automation by 75%.

I've architected LangChain and MCP-based retrieval and prompt-engineering workflows, enabling agentic tool use and function calling with external tools and data sources. I also improved application and inference load times by 40% through profiling, caching, and performance optimisation.

I've delivered end-to-end AI-powered web and mobile products using Python, FastAPI, Django, React.js, and React Native. My work includes containerised AWS deployments, secure JWT-based APIs, MySQL and SQL/NoSQL data pipelines, and concurrent event-driven AI conversations.

I've also built an ElevenLabs and Twilio voice agent, an OCR-powered business card scanner with a RAG knowledge base, and affiliate referral and coupon tracking for Profit Simplified.
