USD 20 /hr

PhD in Mechanical Engineering specializing in artificial intelligence, wearable tech, and biomechanics.

Profile Summary

My expertise involves utilizing machine learning and AI to enhance our understanding of biomechanics. Current projects include using computer vision algorithms for human pose estimation and wearable technology to inform doctors of their patients’ movement patterns. I also build user-friendly websites that are customizable to an end-user bypassing the need to download an app or software. With strong background in startup journey during my PhD, I can share insights on the best practices for starting your business in engineering / health & technology. I was featured on national TV pitch competition for my startup (akin to Shark Tank) and won first place prize, kickstarting my startup and launching our team to new heights. Having extensive experience in guest lectures, publishing journal papers, and networking, feel free to reach out for inquiries on presenting in front of an audience.
