Hi, I'm Mwala and I love building for the web. I have been writing rails programs since 2022 and I have been hooked to this framework ever since. Rails really brings out the creative in me what people online call the developer brain. The framework's full-stack experience is one I have really enjoyed especially when you integrate Hotwire 🔥. I used django before and had a good experience with it won't lie. I have also done so work with Gin with go-lang and React just for the frontend(that what it should be used for). I have done some game development in the past and computer vision work, it was an exciting time. Game dev is something I might go back. Okay, I don't spend all my time on development, I try my best to stay in shape, football (soccer) being my go to sport. I really like watch and playing the sport. I think If I wasn't a developer I would have been playing football professional. I have gotten into the habit of watching the UFC and motorsports, F1 to be specific.
