Interactive UI & Next.js Web App Develop

$18/hr Starting at $25

Slick interfaces and fast-loading apps — built with jQuery, jQuery UI, and Next.js by a developer who has shipped over 100 real-world projects.


Most UI problems aren't framework problems — they're craft problems. Dropdowns that flicker, modals that break on mobile, sortable lists that feel clunky: these are fixable with the right jQuery and jQuery UI implementation. I've been solving exactly these issues since jQuery was new, and I know every edge case.    


On the Next.js side, I build production-ready web applications with server-side rendering, static generation, and API routes — optimised for SEO, Core Web Vitals, and fast initial load. Whether you need a public-facing marketing site, a dashboard, or a full-stack app backed by a REST or GraphQL API, I structure it to scale.    


What I typically deliver:  

  • jQuery UI components: drag-and-drop, sortable tables, date pickers, custom dialogs
  • Legacy jQuery codebase upgrades and bug fixes
  • Next.js apps with SSR, SSG, or ISR depending on your use case
  • API integration: REST, GraphQL, third-party services
  • Performance audits and Core Web Vitals improvements


I work best on projects where you need someone who understands both the browser layer and the server layer — not just a template customiser. Scope is defined up front, delivery is predictable, and I'm available for follow-on support once the project ships.

    We have been working on a project for quite a while. We had to take some of it step by step, but I am pleased that we are getting closer to what I want.

    for Stripe integration into custom website on Dec 03, 2024

  • Volker 2 says,

    This project involved updating the online payment functionality of a website which has been continuously online for the past 19 years. The first online payment functionality were "PayPal Payment Buttons" to which "Stripe Card payments" were added when Stripe only supported credit/debit cards over 5 years ago. Arcmax now implemented Stripe v3 payments which include a PayPal option. While this is tricky (Stripe needs adjustments for additional payment options), he sorted it out and implemented that newer payment gate on three websites. This included another option where a string of up to 450 characters has to be transmitted to Stripe in order to process that information and make it available in email messages to both seller and buyer. This is now also working perfectly.
