Wix Website Developer Needed for Business Website Customization

@ukroficer

✅ Hello, We can improve your existing Wix business site in place: mobile/desktop design, Velo custom JavaScript, Wix CMS dynamic content, and the third-party API/Stripe flow. First we would audit the current Wix pages, HTML/CSS issues, navigation, and performance to separate quick fixes from custom functionality. - Keep it in Wix/Velo, not a separate SPA, to fit the current platform. - Use Figma or current pages as the source for pixel-accurate responsive UI. - Build Wix CMS collections plus Velo API calls and Stripe/payment logic. - Test desktop/mobile, key browsers, forms, API errors, and page speed. We are Webcapitan, a Ukrainian web studio with 8+ years, Preferred Freelancer status, and 5★ feedback across 580+ reviews. Is the improved design already prepared in Figma, or should we redesign inside Wix? Which third-party API and Stripe/payment scenario should the Wix site connect to? Please let me know your thoughts. Looking forward, Roman

Your Wix site already exists, so the real challenge is not starting from zero but cleaning up responsiveness, improving navigation, and adding custom functionality without breaking what is already live. Jobs like this usually go wrong when edits are layered in without tightening structure first, so I’d begin by reviewing the current mobile/desktop issues, existing code conflicts, and where the CMS/API pieces should connect cleanly. I’ve worked on Wix improvement projects involving Velo custom code, dynamic CMS collections, UI cleanup, and third-party integrations where the main goal was to make the site feel smoother and more professional rather than just “different.” That mix of frontend fixes plus functional enhancements is exactly the kind of work I handle regularly. To suggest the cleanest way forward, I’d like to confirm a few points: - Which API needs to be connected, and what data should it send or receive? - Is Stripe already partially set up, or does the payment flow still need to be built? - Can you share the pages where the mobile responsiveness and navigation issues are most noticeable?

Could you please share the existing Wix website URL and confirm which pages or sections require redesign? What custom JavaScript functionality and third-party API integration are needed, and do you already have API documentation and credentials? Please clarify what dynamic content should be managed through Wix CMS and whether existing collections need restructuring. Are there specific desktop/mobile responsiveness issues or HTML/CSS bugs to address? Also, do you have design references, brand guidelines, and target performance metrics for the optimisation work?

Hi, I can customize and improve your existing Wix website with responsive desktop/mobile design, Wix CMS dynamic content, JavaScript functionality, third-party API integration, navigation improvements, HTML/CSS fixes, and performance optimization. I’ll work with the existing site rather than rebuilding unnecessarily and ensure the final experience is clean, responsive, and easy to maintain. Do you already have the API documentation and a list of the current design/functionality issues? Kindly send me a message to discuss more or directly award me. Thank you!

@extreamcode

Hey there, I can see the real issue here: the Wix site isn’t just asking for polish, it needs structure, speed, and a cleaner path for users on every screen size. I’ve worked on Wix customization, responsive fixes, CMS-driven dynamic content, JavaScript behavior, API integrations, and HTML/CSS cleanup, so I can tighten the design without breaking what already works. I’ve shared an initial estimate based on your description, and once we go over a few technical or functional details, I’ll confirm the exact cost and delivery schedule. The goal is to make the site feel built, not patched, while keeping navigation and performance solid. If you want, I can review the current Wix setup, map the CMS and API work, then start with the highest-impact fixes first. What result matters most here: stronger conversions, better mobile UX, or more flexible content management? What is the main conversion goal for the site: leads, bookings, or sales? Looking forward to your reply so we can finalize the exact plan. Best regards, Asad

Hi, I’d love to help improve and customize your existing Wix website. I have strong experience working with Wix, custom JavaScript, HTML/CSS, Wix CMS, API integrations, and responsive website development.

On the functionality side, I can build custom JavaScript features, create dynamic sections using Wix CMS, integrate third-party APIs, and assist with Stripe/payment gateway integration where needed. My approach would be to first review the existing website, identify the current design and functionality issues, and then improve everything while keeping the site clean, fast, responsive, and easy to manage. I’m comfortable working with existing Wix projects and can jump in without needing to rebuild the entire website unnecessarily. I’d be happy to discuss the current website and the specific improvements you have in mind. Best, Nafees

@starttechno

Your existing Wix business website needs more than visual adjustments, so I’ll review the current structure first and improve the desktop and mobile experience without disrupting working pages. I’ll use Wix Velo for custom JavaScript functionality, CMS collections, dynamic pages, conditional content, and reliable third-party API integration. I’ll refine navigation and user flows, correct HTML/CSS and responsive layout issues, and ensure forms, buttons, menus, and content behave consistently across screen sizes. If Stripe or another payment gateway is already part of the site, I’ll verify the payment flow, validation, success/failure states, and secure handling of relevant data. I’ll also optimize images, scripts, CMS queries, and page loading behavior, then test the key journeys on desktop and mobile. I have 10+ years of full-stack development experience and have delivered 249+ projects, including JavaScript applications, API integrations, payment workflows, and responsive websites. I can start by auditing the current Wix Editor/Velo setup and then implement the changes in focused stages. Do you already have the third-party API documentation and credentials available?

You already have the foundation in Wix, so this is really about upgrading usability and functionality without creating new inconsistencies. When a site needs design improvement, responsiveness, CMS content, API work, and code fixes together, the smartest route is to audit the current setup first and then apply the changes in a structured way. My recent work has included Wix customizations with Velo, dynamic content setups, layout correction across breakpoints, and performance-minded frontend fixes. I’ve also worked on sites where navigation and user flow needed improvement because visitors could reach pages, but the experience still felt clunky and unfinished. I can also help make the updated site easier to maintain after the work is done. - Which third-party API are you planning to integrate? - Do you need Stripe for a checkout/payment feature or a simpler payment action? - Are there any reference websites you like for the updated design direction?
