Sangbeom Jo!

Currently, I am mainly working on backend development, and I use Java and Kotlin. When I want to develop a GUI Windows program, I also develop WinForm using C#. Finally, I mainly use C++ to solve algorithm problems.

When developing, my main concern is how to efficiently process a lot of data. If I find a part that can be improved more efficiently, I always think about whether it can be improved through algorithms, query optimization, or CS knowledge.

What I did?

Vinteum

This application analyzes students' schedules by uploading photos of their schedules using AI, and analyzes and provides common free timetables using a line sweeping algorithm. This helps users create their own groups and conduct group activities at common times.
MetaGachon

The reservations for classrooms provided by the software business unit located on campus were originally written by students on paper by hand. After discovering this, we computerized the reservations through an app to improve the inconvenience and linked it with the school so that the faculty could manage the students.
EvaTuna project
2022.01 ~ 2023.11.12

I was in charge of maintaining previously developed plugins (skill system, random teleport, etc.), and developed and maintained a custom land protection plugin. It was a project that achieved a maximum of 100 concurrent users, and I worked on an internal project to integrate multiple servers into a single server through the IPC API.

I was in charge of development and maintenance of random teleport system, skill system, custom essential plugin, daily quest, and other raid-related plugins with Minecraft server for about a year.
Alkaonline project
2017.02.02 ~ 2019.02.06

It was a skyblock server. I developed and maintained a reward system based on contribution to the raid, a custom cooking system, a random box system, daily quests, custom item creation, and special effect plugins.
ComputerInfo

This is a program that uses WMI and various APIs in C# to find out the user's hardware information. After entering high school, the program that used to show memory usage through C/C++ and Win32API was developed into a Winform by studying C#, and features were added.
