About Me

Profile picture

Deepak has built and shipped large-scale machine learning systems across retail, FMCG, search relevance, computational advertising, and voice assistants. He has led work on speech recognition and language understanding at Amazon Alexa, and helped build contextual advertising systems at Amazon Ads.

His work at Alexa included personalized, self-healing error-correction models that learn from user interaction data, enabling runtime query rewriting with low-latency inference paths. His technical focus connects research and production deployment across LLMs, multimodal systems, retrieval-augmented generation, and agents.

He is a Senior Member of IEEE (Seattle Chapter), reviewer for NeurIPS, ICML, KDD, AMLC, ARA, and EMNLP, and advisor to early-stage startups in advertising and healthcare.

Past life: Management consultant for a Fortune-50 CPG/pharma company, advising one of the largest loyalty program rollouts.
