Michael StewartBack End Developer
I'm a Backend Engineer with over 5 years of experience - mostly with Node.js based stacks - , who genuinely enjoys solving real-life problems through coding. I care about deeply understanding the business, and leverage proven design and architecture patterns, such as those in Domain-Driven-Design to craft solutions.
