Setting up your dev environment was meant to be a single command away. And yet, here you are, hours later, just on the cusp of victory, before it turns out that you’re missing yet another API key. You know you probably shouldn’t, but you DM your teammate, let’s call her Fatima, asking her to please send you the credentials. You’ll clean up after yourself, deleting the message as soon as you add the credentials to your environment configuration. https://okal.me/about/ Tue, 08 Sep 2020 03:54:38 +0300 https://okal.me/about/ Hi there. My name is Okal Otieno. I’m a software developer with product experience spanning financial services, data collection and visualisation, messaging, and EdTech. I’ve worked in roles ranging from hands-on development, and architecture, to engineering management. Even the odd bit of UI/UX design in a past life. I currently work as a Tech Lead at JUMO, a financial services technology company. This blog is a catalogue of the joys, frustrations, and - hopefully - brief moments of insight that come with my work. https://okal.me/posts/adventures-in-python-static-analysis/ Tue, 13 Feb 2018 14:07:05 +0300 https://okal.me/posts/adventures-in-python-static-analysis/ I had an opportunity, in mid-2017, to work on tooling to weed out dead code from one of the codebases I work on at Jumo¹. We use an in-house framework for building USSD² applications, the main mode of interaction users have with our lending platform. There isn’t much of a FOSS USSD ecosystem, so the framework had to solve a lot of basic problems in novel ways. Some of the most interesting aspects of it have to do with session management - USSD being a stateless protocol without any widely adopted session management standards, and a metaclass³ based routing model.
