What People Say

Recommendations from colleagues, clients, and industry leaders I've worked with

Jaspreet Singh Oberoi

Jaspreet Singh Oberoi

Technology Leader & Product Growth Strategist

I've had the pleasure of working with Mandeep for over 3 years at Devnagri, where he serves as Chief Technical Architect. When we started facing speed and load-related issues on DOTA Web and our platform, Mandeep didn't just put in a patch, he helped redesign the system architecture to handle 5x the load without too much of extra server hardware.

P

Priya Sharma

VP of Engineering at Shiprocket

Mandeep architected our core logistics platform back in 2014. What's remarkable? The system he built is still running strong today, processing millions of shipments monthly. That's the kind of forward-thinking architecture that stands the test of time. His focus on scalability and maintainability saved us countless rewrites.

I am lucky to have worked with Mandeep, his greatest quality which I witnessed is to get attached to the Idea and understand the vision same as you do. He is not a star, there are many stars out there, he is that black hole who has absorbed millions of stars knowledge and is just sitting there calmly.
