Akshay has worked as part of my team in college and later on various hackathons & projects. He is a resourceful person and has great passion towards solving problems with logical and analytical thinking. He managed & fetched lucrative sponsorships for numerous college events. Moreover, his command on python and Machine Learning techniques has been a major asset for us while working on hackathons and projects. His ability to drive the team towards the deliverables makes him a great team player. He's not afraid to take risks and often suggests new directions to explore. Akshay has my highest recommendation for any future Data Science position he takes up. I’m excited to see the direction in which the organization will grow under his Data Science skills & leadership.

Akshay and I worked together on various data science projects during our Masters, including a capstone Face Recognition project. He efficiently developed the facial modeling and backend architecture of the project under strict time constraints. His tenacity to learn and implement new techniques has helped us take projects well-beyond the planned deliverables. His experience with leading a team and designing software solution architecture was invaluable. Akshay works hard, yet smart to finish any task methodically and completely.
