About Me

With 7+ years of experience and currently serving as a Lead GenAI/ML Engineer, I specialize in designing and deploying advanced LLM-driven agentic applications. My focus is on building scalable, robust, and responsible AI systems that address complex business challenges through frameworks like LangChain and cutting-edge RAG techniques.

I have a strong track record of translating product vision into cloud-native, microservices-based architectures, ensuring scalability and reliability from design to production. My technical leadership spans the full lifecycle — from solution design to observability and monitoring with tools such as Datadog and Databricks.

Deeply engaged with the fast-evolving AI landscape, I stay current with fine-tuning, RLHF, and prompt engineering innovations. I’m equally passionate about mentoring and enabling teams, fostering technical excellence, and driving delivery of high-impact AI solutions.

Beyond my role, I contribute actively to the ML and GenAI community on GitHub and Medium, believing in open collaboration and knowledge sharing as the cornerstone of building the future of AI.
