Simon Lawrence
Lead Software Engineer
I’m Simon, a full-stack engineering lead based in Lancing, West Sussex, with over 15 years in software development. I build enterprise applications, help teams grow, and look for better ways to turn an idea into useful software. I’m happiest when the people around me are learning, sharing knowledge and enjoying what they build.
