At Tudip Digital, I build and deploy enterprise Generative AI systems, RAG pipelines, multimodal architectures, and high-throughput Python backend microservices.

I architected Testily AI, an autonomous validation engine using Python, LangChain, LangGraph, and the Gemini API. It generates structured validation steps and executable scripts from product documentation, reducing manual script creation time by 60%.

I engineer multimodal ReAct reasoning loops, MCP tool integrations, agent memory systems, and dynamic mobile UI testing agents for iOS and Android. My work uses Appium, computer vision, and multimodal LLMs to automate regression testing and identify rendering and performance issues.

I also build production AI infrastructure with Kubernetes, GCP Vertex AI, Pub/Sub, Redis, Docker, and CI/CD pipelines. I improved retrieval latency by 40%, increased system throughput by 35%, and reduced service latency by 25% for Fazor and Nurture Retail.
