Hello again! Thanks for scrolling this far!
I have graduated with a BEng degree in Electrical and Electronics Engineering. My main focus is on building comprehensive full-stack applications. I am also interested in the integration of IoT and embedded systems within our digital world.


When away from the keyboard, I'm usually tinkering with my CNC machine and 3D printer, engaged in a game of chess, or staying active through hiking.


I am currently seeking new opportunities to contribute to exciting projects and collaborate with other developers. If you have a project in mind and think my skills could benefit your vision, please don't hesitate to contact me.

LED Controller for Optimized Plant Growth

This project introduces an IoT-based grow light LED controller system, leveraging the ZigBee protocol for efficient wireless communication. Centered around a Raspberry Pi gateway, the system integrates easy to use graphical interface and embedded system based on a microcontroller.

Quantum Spectrometer

I designed and built a quantum spectrometer that measures and optimizes light composition within the Photosynthetically Active Radiation (PAR) spectrum. This tool aids plant growers, researchers, and lamp manufacturers by providing detailed light quality metrics to enhance plant growth and chemical composition. The spectrometer features PPFD measurements, exposure time adjustment, and spectral corrections, with capabilities for continuous and peak measurements. Implemented on an STM32 microcontroller, it leverages complex signal generation, ADC conversion, and a user-friendly interface.
