I'm a NET Core developer to the bones. My co-workers always describe me as a having integrity, reliable person and I am able to create a trustful environment where candid feedback can flow freely.

Byron has been developing software since he was 9 years old, coding RPG's on his Commodore 64 and his best friend's Apple IIe. When he was just 14, he developed a driver dispatch program for a large home repair company, a pawn shop management program, and a POS for clothing stores (that one is still in production). Since then, software development has been a constant and consuming passion for Byron. In 2010, Byron and some friends founded a software development company, Acklen Avenue, that has now grown to more than 50 distributed employees and runs multiple simultaneous agile software development projects daily. Byron is a true believer in anything that improves software maintainability, usability, and delivery.
I write, nurture and love clean, testable architectures. Language doesn't matter (PHP/C/Rust/Golang/Typescript/Python/Java). I eat two technology stacks and a Linux meal a day. How is that possible? After 15 years of programming, you start to not be in love with your toys anymore like a kid, and treat them as tools instead. What starts to matter after reaching a certain level is expressing ideas with code, not the code itself. It's the ideas that you share with your collegues, as well with the machine, that solve real-world problems that matter. Tools are just that, and in our area of expertise, they change over time quite rapidly. What stays relatively constant are the terminology, the algorithms, and the train of thoughts for solving a specific problem, given a specific scenario. Having worked as a Scrum Master, what matters is also the process of creating software, managing risks and punching the project through any unknowns which might come along.
