Dexter Marks-barber is a Software Engineering Manager at Veson Nautical with around 10 years of experience building and leading engineering teams across web and cloud-native stacks.

Dexter has a track record of quickly stepping into leadership (acting interim lead roles) to introduce testing, sprint workflows, and developer tooling that raise team velocity and quality. His background spans Svelte, Node, PHP, React, cloud services (Cloudflare, GCP), and low-code platforms, giving him a versatile lens for integrating legacy systems with modern delivery practices. Based in Stafford, UK, he’s comfortable balancing people leadership with rolling up his sleeves to fix pagination bugs or implement payroll models in production libraries.
