Experience

The World’s Thinnest Raspberry Pi Tablet

https://cutiepi.io
CutiePi is an open-source project for a tablet based on Raspberry Pi CM4 and Qt Framework.

I contributed to the UI Shell development using Qt QML and some features that include a microcontroller, such as battery monitoring. It ended with a successful fundraising campaign that enabled mass production of the 1st batch.

Early Learning for Kids

http://www.learnwithdanya.com
An interactive platform designed to help toddlers learn numbers and alphabets through engaging, easy games, colorful animations, and audio cues. I implemented it mainly for my 2.5-year-old daughter (Danya) when I noticed she was interested in reading. I brushed it up a little and deployed it as a small educational platform, but it is still considered a project in progress. My QA team (daughter) was absolutely faster than my dev team (me).

WebGL Project for Real-time Video Manipulation

A real-time video processing to display multiple effects, taking into consideration high quality and performance. This includes a large amount of WebGL and Shaders. The product is to run on multiple platforms and environments.
