Aggelos Bellos

Senior Software Engineer

I’m Aggelos Bellos, a senior software engineer on the Architecture Team at Epignosis. My day-to-day revolves around advocating for Domain-Driven Design and Test-Driven Development. When I’m not (politely) annoying people about those, I’m usually doing the same by introducing new rules to our static analysis tools and CI pipeline. Beyond the code, I’m deeply fascinated by socio-technical systems—how social dynamics shape technical architectures, and how those architectures, in turn, influence teams. In my free time, I like to explore scalability challenges and design patterns, and I share my thoughts and solutions on my blog.
