At Tos Analytics, I build Pakodemy, an AI-powered exam preparation platform with 2M+ downloads, 300,000+ questions, 6,000+ video solutions, live classes, and personalized progress tracking.
I restored network visibility across every API call by shipping an in-house React Native network debugger, and replaced a third-party video dependency with a custom React interface bridged to a Swift iOS AVPlayer for 6,000+ videos.
I also built a Python OCR and image-cropping pipeline that reduced textbook digitization from about a week to a few hours, while helping extend the platform from web to iOS and Android.
