Experience

Dating Website

Created a real-world dating website for my final project during university.

Users could create their profiles, upload photos, and fill in their interests and criteria to start the matching processes.

Elevator App

A React Native-based mobile application was developed for elevator users generating various QR codes. The elevator scanner scanned those codes, and it knew where to go. Users had their profiles in the application and could fill their balances.

HTTP Server

I wrote a fully functioning HTTP web server, which could work in the real world. It supported everything that was required in the modern world. I used Python for this project. It was multi-threaded, meaning that it could handle plenty of requests at the same time, providing fast responses

I created an operating system based on C. It was a simple operating system framework for the 80x86 architecture. It supported kernel threads, loading and running user programs, and a file system. I also wrote virtual memory management for this project.
