Cloud & AI/ML Consultant · Corporate Trainer · Indore, India
About Pushpjeet Cholkar
Seventeen years, mostly at the data layer. Cloud & AI/ML consultant and corporate trainer across Oracle, Linux, AWS and data engineering.
I started as an Oracle developer and DBA in 2009, and spent the first decade doing the unglamorous work — tuning queries that had been slow for years, recovering databases at two in the morning, migrating systems that nobody had documented.
Somewhere in there I discovered I was better at explaining it than most people were, and training took over. I've since delivered for Oracle University, AWS reStart, and engineering teams at IBM, Wipro, Accenture, Capgemini and Deutsche Bank, in India and across a dozen other countries, including three teams in the USA as a freelance trainer. In total, more than 3,000 engineers have trained with me.
Today the work splits three ways: consulting on databases and cloud, training engineers and university students, and research into how AI can actually be used to teach — which is where I intend to spend the next stage of my career.

Staying current
Seventeen years only counts if the last year is in it. The stack I teach keeps moving, so I keep showing up where it moves — cloud-native conferences, new Oracle releases the month they land, and the AI tooling that is rewriting how all of this gets built. What I teach on Monday is what I was reading about on Sunday.
Research
I'm working towards a Ph.D. with a target intake of Fall 2028. The research question I keep returning to is whether a language model can genuinely teach — and how you'd measure it if it could.
Primary interests
- RAG-based tutoring systems — retrieval-augmented models as subject tutors, and where the retrieval layer fails students
- Learning analytics — measuring what a learner has actually understood, not what they clicked
- Evaluation of AI tutors — designing benchmarks that reflect learning outcomes rather than answer similarity
- Query optimisation — carried over from seventeen years of tuning work
Teaching & supervision interests
- Database systems — Oracle, SQL, PL/SQL, PostgreSQL, MongoDB
- Data structures and algorithms
- Operating systems — Unix and Linux
- Cloud computing — AWS and Oracle Cloud
- Data warehousing and business intelligence
- Artificial intelligence and machine learning
- Software engineering and project management
Open to research collaboration, co-authorship, and guest lectures. If you're working on AI in education or learning analytics, I'd like to hear from you: contact me.
