About me
I’m curious about how things work, and I usually want to try building something myself.
I’m Teofilus Shaduka, though most people call me Teo. I’m studying cybersecurity, running a small security startup, and building software to solve problems I keep running into. I also make automotive content and take photographs whenever I get the chance.
That probably sounds like a few different directions. To me, they fit together. I like understanding what’s happening beneath the surface, whether I’m looking at a network, a piece of software, a messy workflow, or a car I’ve been wanting to photograph.
Security
I want to understand the risk, not just name the tool.
I’m completing a Bachelor of Computer Science in Cybersecurity at the Namibia University of Science and Technology. The subject interests me because security is tied to how people and systems actually behave. A technical weakness matters, but so does the information people make public, the assumptions they rely on, and the way a risk gets explained to the person who can do something about it.
That thinking is part of why I started Principia Works. The company helps people and organisations understand what their public digital footprint can reveal and what they can do to reduce unnecessary exposure. I want security advice to be grounded in evidence and useful to people who don’t spend their day thinking about security.
Building things
If a problem keeps getting in my way, I start wondering whether I can build a better way to handle it.
Argus came out of the frustration of tracking opportunities, requirements and deadlines across too many places. My video editing tool came from wanting to spend less time sorting footage and more time making a good video. I’ve also built AI-assisted workflows to turn long meeting recordings into structured minutes and action items.
I work mainly with Python and JavaScript, alongside the frameworks and tools each project needs. I like software that has a clear purpose, doesn’t make people jump through unnecessary hoops, and doesn’t need an elaborate system just to do its job. I pay attention to privacy and the limitations of automation, too. If a tool is helping with a decision, I want people to understand what it has done and still have a say in what happens next.
Cars and the camera
This started long before I thought of it as a project.
I grew up watching Top Gear and Jeremy Clarkson, and cars have been a constant interest ever since. Pops & Bangs gives me a way to share that interest through reviews, video and photography. I present, film, edit and photograph the work myself, which means I’m always learning something new about the creative side as well as the technical side.
Photography has become its own habit. I like the details people can walk past without noticing: a headlight, the line of a wing, a wheel setup, or the way the light changes a car’s paint. Sometimes the photograph is the whole point; sometimes it’s part of a bigger story.

Away from the screen
When I’m not at a keyboard or behind a camera, I’d rather get outside for a while, explore a trail or the hills, play tennis, or spend a quiet afternoon with good friends. There is always another thing to learn or build, but not every good idea comes from sitting in front of a screen.
