About this service

Summary

Unlike traditional multi-page websites, a single page application (SPA) offers lightning-fast navigation and a smooth, app-like experience for users. I specialize in building SPAs that not only feel fast and fluid but are also thoughtfully structured behind the scenes. Each app is tailored to your functionality goals — whether you're building a dashboard, a landing page with dynamic content, or a lightweight web app. My development process ensures performance, responsiveness, and future scalability without the complexity of unnecessary tools.

Process

Discovery Call We’ll start with a conversation to understand your app’s purpose, features, branding needs, and user goals.

Planning & Architecture I’ll draft the architecture of your SPA, including component structure, state management strategy, and data flow.

Development Your SPA is built using React (or Vue, if preferred), applying modern development practices and tools. API integration and core functionality are added incrementally.

Feedback & Iteration You’ll receive regular updates or staging links for review. I welcome feedback early and often to align the app with your vision.

QA & Optimization Cross-browser testing, mobile responsiveness checks, performance tuning, and accessibility improvements are made during this phase.

Delivery & Launch The final SPA is delivered ready for production. I’ll assist with deployment or hand everything off with documentation as needed.

FAQs

What’s the difference between a SPA and a regular website?
An SPA loads once and dynamically updates content without refreshing the page, offering faster interactions and a smoother user experience.
Is this mobile-friendly?
Yes! Your SPA will be fully responsive and tested across common screen sizes.
Can you connect the SPA to a backend or CMS?
Absolutely — I can connect your app to APIs, headless CMSs (like Sanity or Strapi), Firebase, Supabase, or any backend service.
Can I update the content later?
If you’d like editable content, I can set up integrations with a CMS or provide clear documentation to help you manage updates manually.
What tech stack do you use for SPAs?
I mainly use React (with tools like Vite or Next.js), but I’m flexible based on your needs and can incorporate TypeScript, TailwindCSS, or other tools as necessary.
