Hire mid-level Ruby on Rails developers

My journey into software development started with a deep curiosity about how systems scale and handle complex workflows. Over the last 4 years, I’ve specialized in Ruby on Rails, PostgreSQL, and system optimization, working on high-impact financial platforms. At Vartana, I led the complete revamp of the servicing system, transitioning from invoices to account statements, improving financial tracking, and optimizing execution times by 67%. I also played a key role in migrating our entire system to Kubernetes, reducing deployment time by 83% while ensuring zero downtime. Beyond writing efficient and maintainable code, I excel at troubleshooting critical issues, optimizing SQL queries, and enhancing system performance. One of my proudest achievements was reducing page load times by 90% (20s → 2s), significantly improving the user experience. I’m passionate about scalability, DevOps, and financial systems—I love architecting solutions that not only work but scale seamlessly. Whether it's optimizing background jobs, improving API performance, or automating workflows, I thrive on making systems faster, more efficient, and easier to maintain. When others see a bottleneck, I see an opportunity to optimize. My unique skill set lies in blending backend development with DevOps, ensuring that applications run smoothly while remaining scalable and cost-effective. I’m always eager to collaborate with teams that value clean code, performance, and reliability. I’m open to remote opportunities where I can contribute my expertise in Rails, Postgres, and system architecture. Let’s build something great together!

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 watching 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 and tennis, man I wish I knew how good this game was.
