Frontend development FAQs

Can you work alongside our agency or internal product team?

Yes. I provide senior frontend development for agencies, startups, and product teams, working alongside designers, backend developers, and technical leads. I can join your existing codebase and delivery process, with an agreed scope and clear communication throughout.

You work directly with me as an experienced engineer. I also provide white-label frontend development for agencies that need a dependable technical partner to deliver work under their brand.

Can you turn our Figma designs into a working website or application?

Yes. I translate Figma designs and supplied layouts into responsive HTML, CSS, and JavaScript, including React, Vue.js, or Svelte interfaces where appropriate. I also use Alpine.js for lightweight interactions within otherwise server-rendered pages. The work covers more than individual screens: navigation, interactive states, form behaviour, and layouts across different screen sizes all need consideration.

I work with your designers to resolve gaps in the designs and build reusable components that preserve the intended appearance while supporting ongoing development.

Can you build the frontend for our startup or SaaS product?

Yes. I build product interfaces for startups and SaaS teams, including onboarding, dashboards, customer accounts, reporting, and multi-step workflows. I can work from established designs or help clarify the implementation requirements with your team.

For an initial release, I focus on the journeys users need to complete and the integrations required to make them work. This helps establish a useful scope while leaving room to improve the product as you learn from customers.

Can you build single-page applications with React or Vue.js?

Yes. I build single-page applications (SPAs) using React or Vue.js, as well as interactive applications with Svelte. These can suit dashboards, customer portals, and other interfaces where users move between tasks and work with changing data.

I consider routing, loading and error states, accessibility, and API integration as part of the build. An SPA is not the right choice for every website: public content and search visibility requirements also influence how pages should be rendered.

Can you improve or extend an existing frontend application?

Yes. I can join an existing frontend project to develop features, resolve interface problems, or improve the underlying code. I start by understanding the application, its framework, and the way your team maintains it.

Depending on the requirements, this may involve improving components, updating layouts, simplifying complex interactions, or addressing performance issues. I assess what can be retained before recommending substantial changes or a rebuild.

Can you develop a headless website or CMS frontend?

Yes. I build headless websites where a separate frontend retrieves content from a CMS through APIs, including headless WordPress. This can support bespoke interfaces and allow content to be used across different sites or applications.

I can work with your existing backend team or provide WordPress development and Laravel application development where needed. Headless architecture introduces additional integration and maintenance considerations, so I help assess whether those trade-offs are worthwhile for your project.

Can you build reusable components and implement a design system?

Yes. I can turn an existing design system into reusable frontend components, with consistent styling, behaviour, and responsive layouts. This helps your team build new screens without repeatedly recreating the same interface elements.

I work with your designers to clarify component states, variations, and usage. The implementation can use JavaScript or TypeScript within your chosen framework, with the structure and documentation shaped around how your team will maintain it.

How do you approach accessibility, responsive layouts, and browser compatibility?

I consider semantic HTML, keyboard interaction, focus states, form labels, and responsive behaviour during implementation. Interfaces should remain usable across screen sizes and input methods, rather than simply shrink to fit a mobile screen.

I agree the relevant browser coverage and accessibility requirements with you, then test representative screens and journeys. Where a formal accessibility audit is required, its scope should be agreed separately from routine development checks.

Can you improve frontend performance and Core Web Vitals?

Yes. I investigate what is affecting loading speed, responsiveness, and layout stability before recommending changes. This can include JavaScript bundles, images, fonts, rendering behaviour, and third-party scripts.

I use Core Web Vitals alongside the actual user journeys to identify worthwhile improvements. Where problems originate in APIs, server responses, or hosting, my broader development experience helps assess those dependencies too. Results depend on the application and the services it relies on.

Do we need finished designs before you can start?

Not necessarily. Wireframes, an existing product, or a partially developed design can be enough to begin discussing scope and technical requirements. Before implementing a feature, we need sufficient clarity about how it should look and behave.

I can collaborate with your design and UX team to work through those details. If you need additional expertise, I can introduce trusted specialists while remaining your technical lead for frontend development.

Can we hire you for a project or an ongoing frontend contract?

Yes. I take on defined frontend projects and ongoing contract development, with the scope, capacity, and working arrangements agreed around your needs. This can suit an agency delivering a client project or a startup developing its product over successive releases.

I’m a senior freelance frontend developer based in Bristol, working with teams across the UK and internationally. Continued involvement gives you an engineer who understands the interface, codebase, and decisions behind it.

How do you estimate frontend development work?

I review the designs or existing application alongside the functionality, integrations, and delivery requirements. The number of screens is only part of the scope: responsive layouts, component variations, interactive states, and connections to real data also affect the work.

Sharing your Figma files or product link, current technology stack, priorities, timeline, and budget parameters helps me assess the project. Where requirements are still developing, we can identify a focused first phase before estimating the wider build.
