Hire the Best HaXe Developers & Programmers
in Ukraine

Hi, I'm a senior web developer with 14+ years of experience building websites and custom integrations for businesses and digital agencies. I can join an existing project, solve technical problems quickly, or take ownership of the development from start to finish. What I can help with: • Custom WordPress development (ACF, Gutenberg, WooCommerce) • Astro websites and modern static frontends • Figma to WordPress or Astro • Website design and redesign • API integrations (Odoo, CRM, payment systems, third-party services) • Website maintenance, bug fixing, and long-term support • Performance optimization (Core Web Vitals, PageSpeed) • Structure websites so they're technically optimized for both search engines and AI-powered search experiences. • Website migrations (Webflow, Wix, Framer, ClickFunnels → WordPress/Astro) • Headless CMS (Storyblok, Strapi, Contentful, Keystatic) I also build business automations using Python, n8n, Make, Zapier and AI tools where they provide real business value - for example automating repetitive workflows, connecting business systems, or processing data. Why clients work with me: • 10+ years of commercial development experience • 100% Job Success on Upwork • Reliable with deadlines • Comfortable working independently or as part of an agency team • Long-term support after launch If you're looking for someone who can both build and maintain your website - and connect it with the rest of your business systems - I'd be happy to discuss your project.

I help teams get Wix Studio sites that actually run the business — bookings, calculators, member areas, admin tools, CRM/API sync — and when Wix hits a wall, I build what’s missing: custom scripts, parsers, scrapers, database workflows, and API hooks. Wix Studio & Velo → Custom checkout & forms, Velo backend (.web.js), databases, CRM/API sync, webhooks → Auth & member areas: sign-up/login, customer dashboards, gated content, role-based access → Custom elements, HTML embeds, JavaScript, CSS — when Editor limits aren’t enough SEO: → Technical SEO: metadata, indexing, sitemaps, redirects & crawl optimization → On-page SEO: semantic structure, internal linking & content optimization → Structured data: rich snippets, FAQ & custom JSON-LD → Core Web Vitals & performance optimization for better search rankings Outside Wix → Python: parsers, scrapers, cleanup, scheduled jobs → Databases & APIs: CRM, sheets, catalogs, webhooks → Glue between your site and the rest of your stack I’m also happy with straightforward editor work — new pages, CMS, forms, quick fixes. Clear scope, clean code, and I stay reachable until it’s live. ✉ Send your site or a short brief — I’ll tell you straight whether Wix-native, Velo, or a bit of custom code is the smart move.
