Senior Software Engineer

Inflo – Remote, United Kingdom

I helped a 7-person Scrum team deliver projects smoothly by streamlining workflows and reviewing a bunch of pull requests, getting some major features out within a few months. I built a Git hook and .NET tool to make code reviews and deployments a bit quicker across several teams. I also set up some unit testing guidelines and shared SOLID principles with a few teams, making tests more consistent. Plus, I worked on onboarding and recruitment, including interviews and tech test reviews, and helped bring on some new engineers.
