Experience

Dating Website

Created a real-world dating website for my final project during university. The project consisted of two parts: a web service, including ASP.NET core web API, and an Angular-based single-page application. Users could create their profiles, upload photos, and fill in their interests and criteria to start the matching processes.

Loan Management System

A .NET-based windows application for banks. Bank employees could create new loan applications and disburse them. It was a real-world loan management system used by every Georgian bank and had millions of loans registered and managed by our system.

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

Operating System

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.
