Experience

Firmware for IoT Gateway

https://glass-link.io

Firmware for a gateway running on Raspberry PI in real-time interfacing data from a radio-frequency (RF) module with the cloud application. Secured the communication over the WebSocket interface in a custom-designed protocol based on JSON.

Service to Convert Slides to 3D Engaging Presentations

https://wow3d.me/

Developed a custom OpenGL-based real-time graphics render engine that became the core of the web platform to convert PowerPoint slides to 3D animated, engaging presentations. Used by SIEMENS, Accenture, EY, Dassault Systems, HP, and many more companies.

Firmware for Magnetic Resonance Receivers

I designed and developed a multi-threaded embedded device firmware application to gather real-time data from magnetic resonance receivers. Part of the development involved applying IFFT and other signal-processing techniques to the collected data to produce enhanced images.
