A passionate software engineer and instructor, Dheeru has 10 years of experience developing innovative software for start-ups in silicon valley and elsewhere. He holds a Ph.D. in Computer Science from University of Louisiana at Lafayette (USA). His expertise includes developing complex Web data integration & mining software with Java as the main programming language. Coming from the start-up world, he also has extensive end-to-end experience in developing Web applications using frameworks/tools such as Spring, Hibernate, Solr, MySql, etc. Dheeru is passionate about developing products that are easy-to-use, intelligent, and well-architected. Writing well-crafted code that follows the best design practices is of utmost importance to him. He brings the same level of passion and completeness to his teaching. Every concept is covered at a very in-depth level clearly explaining the motivation behind their introduction. He strongly believes in "learn by involving" teaching principle and thus his courses involve tons of live demos, an industry standard project, and several quizzes.

Before NimbleCommerce, he worked as a Research Scientist at Local Corporation, a local search company in Irvine, California. He also published and presented half-a-dozen research papers at top conferences and workshops such as International Conference on Data Mining (ICDM) and Geographic Information Retrieval (GIR). During his graduate-school days, as a teaching assistant for Search & Data Mining courses, he designed course assignments and often gave guest lectures on Web data mining.
