With active involvment in both dev and ops I help my clients achieve the focus needed to deliver results. I am comfortable with software development (mostly in Go at the moment) but also with infrastructure and code and setting up efficient delivery pipelines. I advocate devops best practices and mentor colleagues in areas when they need improvement. At the same time I seek collaboration with more experienced colleagues so that I keep improving as well.
