Career & interview guidance

IIT Bombay Alumnus

Institute Rank 2

πŸ‘¨β€πŸ’» At Microsoft, I work as an SWE II on the M365 Copilot Extensibility Platform, helping users build intelligent agents and workflows inside Microsoft 365. Previously, I was a Data & Applied Scientist on Bing Autosuggest and Search History, shaping how millions interact with search.

πŸ“˜ I'm the author of Beyond Code β€” a bestselling career guide for developers and data scientists navigating the real-world challenges of tech.

🧠 As a Top 1% AI & Data Science mentor on Topmate, I've guided hundreds through interviews, career transitions, and AI consulting. I also conduct workshops, deliver talks, and share insights on LinkedIn, where I actively post about AI engineering, data science, and career growth.

✍️ I write technical blogs on Medium and co-authored The Vision, Debugged, a newsletter on cutting-edge AI innovations.

πŸŽ“ I graduated from IIT Bombay with Dept. Rank 1 and Insti Rank 2, majoring in Mechanical Engineering and minoring in CSE. I was also AIR 1 in ICSE 10th Grade across India.

🎢 Beyond tech, I'm a trained vocalist, avid reader, and visual artist with 3 solo painting exhibitions. You'll often find me sharing covers on YouTube, exploring new books, or building side projects at hackathons.

What People Say

Testimonials from mentees and colleagues

As someone trying to transition into industry from academia, the session with Tezan was very insightful. Tezan went above and beyond in trying to understand my needs and help me identify key gaps in my knowledge. I highly recommend Tezan to anyone in a similar position or just trying to get a better grasp of the data science interview process.

Aishwarya Kumar

Researcher @ Frontier Development Lab

Tezan is a great mentor. He was well on time and we had a great mock up interview session. He is constructive in providing feedback and insightful tips. Would definitely recommend him for Mock Data Science Interviews.

Abhishek Harikumar Narayanan

Data Analytics @ WPP Media

Tezan has been a phenomenal asset to the team. His ability to analyze a problem, present solutions, and execute tasks in a time pressured environment has been outstanding. His ability to take direction and analyze a solution that incorporates the bigger picture is that of someone with 10+ years of experience in the field.

Sam Lester

Co-Founder @ WalletSocket Inc.

Tezan worked with me as part of Google Summer of Code. One thing that was clear from the beginning when he submitted his proposal was his attention to details. Out of the many proposals we received this year he was one of the top candidates and was selected to work with us.

The first month he designed an API with feedback from us, and also learned how build and work with the PEcAn system (a complex system that consists of many micro services that interact with each other). During this time he also learned how to work with the R programming language.

The second and third months he spend time on implementing all the features from his proposal, including a library that will interact with the PEcAn system. Many of the users of the PEcAn system have already shown interest in being able to use both the API and the library to do their research in the future.

I highly recommend Tezan for his ability to understand the problem, create a solution and implement the solution. His implementation skills and communications skills are excellent and he is a great person to be working with.

Rob Kooper

Project Leader & Research Scientist @ PEcAn Project

Tezan is very experienced professional, he can help me to present and think in a higher level of the overall business and strategy, I learned a lot from him! It's great to have mock interview with Tezan. The questions asked is so interesting and inspiring.

Qihuan (Abby) He

Northeastern University, Silicon Valley Campus

The discussion was exactly what I was hoping for and provided me with significant insights from an industry perspective!

Durga Shree Nagabushanam

Research Assistant @ Carnegie Mellon University

The session was incredibly insightful and helpful. Coming from a Mechanical Engineering background, I had several doubts about transitioning into Data Science, and he answered all of them clearly and thoroughly. He explained how I could bridge the gap between these two fields and provided a clear, actionable plan.
