Breaking the Myths Around Tech
I’ve always been someone who likes to see evidence of my work . The kind of person who would understand an architect saying, “I designed that house.” Something physical. Something visible. Something you can point to and say, I was part of that. That instinct shaped me long before tech ever entered the picture. I’ve always loved design . Not formally. Not academically. Just naturally. I taught myself Canva because I had to design flyers while I was in network marketing. I lea

Debugging Wikipedia API Integration: How Geography Finally Caught Up With Me
Gazetteer If you had told my secondary-school self that one day I’d be building a map , I would have laughed. Loudly. I was an art student —the creative kind—but I still did some science subjects. I even had an A in biology. LOL. So no, I wasn’t dull. I just had very clear opinions about certain subjects. Geography was one of them. Anything involving calculations? Latitudes? Longitudes?

I was doing just fine… until I encountered Promises in JavaScript. From the start of the module, my course provider warned us: “This is one of the m

My First Full-Stack Project: The Testing Mistake I Made (So You Don’t Have To)
When I started building my first full-stack project, I didn’t follow a Test-Driven Development (TDD) workflow. Like many beginners, I built my backend routes first and told myself I would “write the tests later”. Later arrived…and brought confusion with it. When I finally started writing my tests with Jest and Supertest, I made a big beginner mistake: I rewrote my entire route logic inside the test files. Every test suite became almost as long as my route file. My tests were
