What colleagues say
“Siddharth is one of the most gifted engineers I have worked with. His grasp over mobile app development is not just extremely sound from a technical perspective but his design sense and a remarkable ability to put himself in the user's shoes helps him excel where a lot of android engineers of his experience level can't.”
Dipesh Mittal
CTO @ DrDroid (YC W23) · Managed Siddharth directly
“If there's one thing I learned working with Siddharth, it's that speed and stability don't have to be trade-offs. He has an engineer's discipline paired with a builder's urgency, and that combination is hard to find.”
