About me

Reneilwe Seleka

I'm Reneilwe Seleka, an aspiring Frontend Web Developer and Software Engineer with a passion for crafting clean, purposeful digital experiences.

I believe great software is both functional and beautiful — built with intention from the first line of code to the last pixel. I'm continuously learning, building, and pushing myself to grow in the ever-evolving world of web development.

Whether it's architecting a responsive UI or diving into full-stack problem-solving, I bring curiosity and care to everything I build.

The site includes interactive product displays, search and filtering, form validation with email integration, and a mobile-friendly navigation system.

Mobile OS UI · In Progress

A front-end concept of a mobile operating system home screen built entirely in the browser with plain HTML, CSS, and JavaScript. Features a live status bar with real-time clock, dynamic date widget, home screen widgets, an interactive 8-app grid with custom icon uploads via FileReader, and a bottom navigation bar — all contained in a phone-frame layout that simulates a real device viewport.

QuickChat (Desktop Messaging Application)

A Java desktop messaging application that simulates the core features of a modern chat platform. As one of the first projects I built, it helped me develop a strong foundation in object-oriented programming, GUI development, file handling, and multithreading. The application allows users to send, store, search, and manage messages while maintaining local data persistence through file storage.
