Santosh Kathait

Innovative Engineering Leader with 13 years of total experience (10 years Android, 3 years React Native), specializing in the intersection of high-performance mobile architecture and Generative AI. Over the past few years, I have pivoted into the AI/ML space, leveraging RAG (Retrieval-Augmented Generation) systems and integrating LLMs like Google Gemini into mobile ecosystems. I bring a unique dual-expertise: the ability to build scalable, modular mobile applications for teams of 200+, and the technical depth to develop Python-based AI prototypes—ranging from Computer Vision (OCR) to Neural Networks (ANN).
