This article shows how I improved the accessibility of a simple GitHub Timeline app I built.
A few weeks ago, I worked on a little GitHub Timeline project. When you enter a user’s username you can view a timeline of their public repositories in a chronological order — the most recent repo on top.

Everything worked perfectly, right? I ensured it was responsive, the font and colours looked okay, and I ensured…
Below are examples of O(n^2) solutions (quadratic time) to common array problems. We will explore other options for solving with the aim of improving performance.
Problematic: For each element, loop through the array to see if there is another element like it. …
This article shows how I went from having a nav bar without keyboard navigation, to having one in the recommended approach.

We started off with an overview of the updates from F8. Our lead, Gertrude talked through some of the…
Web scraping is a method of extracting data from websites and the data is afterwards saved on a local resource i.e database.
Data displayed on a website can only be viewed and to get a copy of it you would have to manually copy and paste. Web scraping enables you to automate gathering data from a website.

On the 28th of April 2018 Facebook launched Developer Circles in Eldoret at Sirikwa Hotel.
Attendants started showing up way before the scheduled event time, so eager to learn and interact with others. Making their way from near and far, we had people traveling from different parts of Kenya to be part of the event. We also had a variety of engineers in the tech industry from Android developers to Web developers, the whole wazoo came to share and learn, it was a full house.
