Sinoxolo.

My people call me Gee. I build things, I break things ethically, and I keep going — even when I'm not sure exactly where I'm headed. That's always been enough.

Client satisfaction

Good software.
Every time.

I don't just write code. I build things that work, that look right, and that people actually want to use.

01 /

Web Development

React, Next.js, Node.js. Fast, clean and built to last. I care about the details because the details matter.

02 /

Security & Ethical Hacking

TryHackMe, HackTheBox, Kali Linux. I'm learning to break things so I can build better things.

Data & Python

ETL, Pandas, Matplotlib. Raw numbers turned into something someone can actually make a decision with.

04 /

Mobile Apps

React Native and Expo. Native feel on iOS and Android from one codebase.

Exploring Flutter next
05 /

Backend & APIs

Node.js, Express, Supabase, PostgreSQL. Solid foundations for things that need to scale.

06 /

Always Learning

Rust, WebAssembly, Machine Learning. The stack keeps growing because I keep growing.

Ready to work together?

If you've got a project, an idea, or just want to talk — I'm here.

Just a guy
who didn't stop.

From the hood to university. First job, second job. Still going up.

The story

I'm Sinoxolo — Gee to my friends. Just a guy from Johannesburg who didn't stop doing things. Finished high school, didn't fail nothing. Made it to UJ, did the course, finished it.

Got my first job right after uni. Now I'm at my second. And this is not my last — I'm still going up. That's the thing with me: I keep elevating.

I'm not always sure exactly what I'm doing, but I keep doing it anyway. And I know it's going to work out. You've got to trust yourself and put yourself in situations where the universe has no other option but to let you rise.

I build software. I learn security. I'm passionate about growing — and I want to take people with me on that journey.

What drives me

🎯

Precision

Every line of code is intentional. I approach software like a strategist — deliberate and always thinking ahead.

🔍

Curiosity

Python, C#, React, Kali Linux — I dive into everything. The learning never stops because I never want it to.

🚀

Elevation

I'm going up. Not because of luck — because I trust myself and keep putting myself in the right rooms.

Things I've built.

Real software, real problems, real solutions. Every project taught me something.
