What I'm looking for

I seek roles building production AI/ML systems—agentic AI, voice agents, or computer vision—on collaborative teams with impact, scalability, and opportunities to lead technical design.

I have 10 years of experience solving real-world challenges across multiple industries like healthcare, law, education and so on. I specailize in developing AI-powered solutions such as chatbots, AI agents(MCP/Agentic/Voice), Prompmt Engineering, implementing RAG system, and LLM models(training, deployment, and fine-tuning). With a deep understanding of both AI/ML and web/mobile technologies, I provide end-to-end solutions from conceptualizing AI models to integrating them into practical, scalable application. My track record of successful projects across multiple industries ensures that I can deliver high-quality, tailored solutions that meet your specific needs.
