Heyo, I’m Ethan Kletschke! I'm a South African second-year Bachelor of Computer Science student at Emeris in Sandton, Johannesburg.

• I’m mostly interested in web development, but am well-versed in a wide variety of programming languages related to software and web apps.
  • See my portfolio app here.

• Fun facts:
  • My birthday is on 2006-12-06
  • I'm currently studying at Emeris Sandton.
  • I taught myself the basics of many programming languages, listed here, as well as most of what I know.
  • I use AI sometimes for debugging or explaining concepts, but I prefer writing my own code. I’m here to actually learn, not just generate projects.

I am proficient in:

• JavaScript (Both node.js and web development)
• TypeScript
• React
• CSS
• HTML
• Git

And I know at least the basics of:

• Basic SQL
• PostgreSQL
• Bash scripting for Linux (practiced via the Windows Subsystem for Linux (WSL))
• Java (From my 1st year of university)
• C# (From my 2nd year of university)
• Pascal (Delphi specifically, from high school)
• Python

I use COBOL very rarely for hobby projects (specifically GnuCOBOL, using Arnold Trembley's pre-built Windows binary).

I have previously experimented to varying degrees with the languages and frameworks listed below. Unless otherwise specified, I do not use these languages and frameworks anymore.

• Perl
• C++
• Bootstrap 4
• Bootstrap 5
• PHP
• Material UI (React)
• jQuery
• Makefile
• XML
• XSD
• Extended Backus-Naur Form (EBNF)
  • Specifically, in my repository "E-Calc", I used the stricter ISO standard for EBNF to create a basic calculator and assignment language.
• XML DTDs

I am familiar with the following concepts:

• Conventional Commits (Git)
• Signed Commits and Tags with GPG keys
• Data Structures and Algorithms
• GitHub repositories (I currently have 22 public repos all made by myself as of 2026-03-21)

I am currently learning:

• Accessibility in Web Development
  • aria attributes
  • Contrast ratios
• Bash Scripting
