Experience

David Holt

Full-stack developer with a design background, focused on building scalable, maintainable systems that perform well and feel great to use.

I design and build modern web applications — from CMS-powered platforms and booking flows to custom APIs and accessible user interfaces. With over a decade of experience, I care about writing code that lasts, works hard, and stays easy to work with.

Web Developer

Worked across two generations of the company’s digital platform — first maintaining and extending a legacy Umbraco 7 MVC site, and now contributing to a modern headless setup built on Umbraco 10, Nuxt, and .NET Core.

  • Developed features across the stack: front-end components, CMS workflows, APIs, and data handling.
  • Delivered end-to-end solutions including a custom Net Promoter Score (NPS) system and a customer experience platform — both built with Azure Blob Storage and Entity Framework, featuring back-office management and reporting dashboards.
  • Led technical enhancements across performance, accessibility, analytics, and automation — including page speed optimisation, Google Analytics data-layer integration, cookie consent and CMP implementation, and automated content imports from third-party APIs and partner feeds.
  • Worked within a modern n-tier architecture using CQRS (with MediatR), Redis caching, and Azure Storage Queues to support scalable data flow and background processing.
  • Collaborated closely with business stakeholders, designers, and QA to align technical solutions with commercial goals.

  • Built and maintained front-end architecture using HTML, CSS, JavaScript, and jQuery — ensuring performance, accessibility, and maintainability.
  • Partnered with back-end engineers to integrate UI components into fully functional web applications, ensuring consistency across systems.
  • Led brand and design efforts across internal projects — establishing visual guidelines and creating reusable asset libraries.
