Cases

How can I help you?

  • Architecture

    From setting up your codebase with for example an NX monorepo, Domain Driven Design, the sense and nonsense of microfrontends, the use of Tailwind CSS and your deployment strategy. Through my years of enterprise experience I know what works in the long term and what makes developers happy.

  • Pixel perfect design

    Working with UX’ers and Visual Designers to come up with a solution that works for the end user, but is also performant and does not compromise on code quality, that is what gives me energy. I like to work with designers who, in addition to their own toolkit such as Figma, also know what is possible with code, such as HTML5 and CSS3, together we create the coolest solutions with Storybook for example.

  • Team lead van een SCRUM team

    Is your front-end team not running optimally, but you don’t know why? With my years of experience with SCRUM teams, I know quite well how to expose pain points and discuss and tackle them as a team. I do not avoid a good progressive discussion, ultimately we all want to achieve the same goal and create more autonomy as a team.

  • Accessibility

    As a front-end developer you can make a difference here. In recent years I have worked at many (semi) government agencies, where WCAG accessibility is simply a requirement. From simple contrast ratios and image descriptions to advanced ARIA tag constructions. I know the tools and guidelines and know when to apply what.

  • Craft CMS Development

    In addition to front-end development, I also accept full-stack assignments. For years, I have been using Craft CMS. A versatile Content Management System (CMS) based on PHP with many application possibilities. From a simple blog to a custom website for your startup, but also advanced content structures, forms and APIs with GraphQL are among the possibilities. Are you looking for customization? I am also available for custom Craft CMS plugin development.

  • One-time code assessment

    Are you looking for someone who can do a code assessment of your front-end codebase, pipelines and/or deployment strategy? With years of experience for enterprise applications I know quite well what best practices are and where pain points lie. Contact me for a review resulting in a report with recommendations. Possibilities can of course be discussed, minimum duration is 16 hours.

  • Part-time consultancy

    For many start-ups full-time consultancy is not immediately necessary, that is why I am available for 16-24 hours per week for part-time consultancy. Think of architecture issues, refining stories and 1:1 calls for questions. I am available for the team to recognize potential problems early and create clear solution directions, which the team can then work out.

Skills & Techstack

I like to describe myself as T-shaped, where my core knowledge lies in front-end architecture and development including the devops facets of the profession. Think of advanced CI/CD pipelines, automated testing and code quality. See below a selection of my skills and tech stack with which I have a lot of enterprise experience and I can definitely help your team with.
