Hire the Best Front-End Developers
in Kazakhstan

I'm a WordPress developer with 7+ years of experience. I handle the full spectrum of WordPress work: bug fixes, migrations, maintenance, speed optimization, and archive restoration. Whether your site is showing a white screen after a plugin update, you need to migrate hosts without losing SEO, your PageSpeed score is in the red, or you need to recover a lost site from the Wayback Machine - I can help. Every project gets the same approach: diagnose the root cause, fix it properly, and explain what happened in plain English. What I work on: - Bug fixes: white screen, plugin conflicts, PHP errors, broken WooCommerce - Migration: host-to-host, domain transfers, HTML to WordPress (zero downtime) - Maintenance: updates, backups, monitoring, security (single sites or networks) - Speed optimization: Core Web Vitals to green, before/after metrics - Archive restoration: Wayback Machine to WordPress, including parametric URLs How I work: - Fixed price agreed upfront. No hourly billing, no surprise invoices. - I test updates and changes on staging before touching your live site. - You get a plain-English explanation of what was wrong and what I changed. - Direct communication via Upwork - response within one business day. I maintain a network of 50+ WordPress sites for a client, so I've seen every bug, every migration edge case, and every hosting quirk. That experience means faster fixes and fewer mistakes on your project.

Senior front-end developer with 10+ years of experience building production web apps with Vue, React, TypeScript, and modern JavaScript. I help teams fix messy UI code, improve component architecture, ship polished responsive interfaces, and make complex features easier to maintain.

I bring solutions with Javascript. From frontend to backend. I feel deeply familiar with Vue and Nuxt, but I'm highly flexible

Hi, I'm Sergey. I build and fix websites and web apps. Work I take on: - Full-stack: Next.js / React + Node.js APIs, auth, payments, integrations - CMS work when that's what the project needs: WordPress, Squarespace, sometimes Webflow or Tilda - I can build from your Figma file, or from a brief if that's all you have - Updates and forms on a site that's already live When we're done, your team should be able to change copy and pages without me. Written scope, preview links, milestones. Updates in Upwork messages. I check the site on a phone and that the form actually sends before I call it done. Live sites are on my profile. I use React, Next.js, TypeScript, Node.js, PostgreSQL, Vercel - or I stay on the CMS you already have.

Figma to Webflow, Webflow Redesign, and Webflow Development work is focused on measurable results: 200+ Webflow projects delivered, 200+ Figma to Webflow pages converted, 3 to 5 responsive breakpoints tested per page, 100% Webflow QA before handoff, and up to 90% visual alignment with the approved Figma design. I build Webflow landing pages, Webflow marketing websites, Webflow business websites, Webflow CMS websites, Webflow redesigns, and WordPress to Webflow migrations with clean Webflow structure, organized Webflow classes, reusable Webflow components, and launch-ready implementation. For Webflow redesign projects, I focus on improving layout quality, responsive behavior, SEO structure, page speed, editing flexibility, and long-term maintainability. My Webflow redesign process can reduce redesign rework by 20% to 40% during QA and reduce post-launch Webflow layout fixes by 30% to 70% through cleaner spacing, better section hierarchy, responsive testing, and stronger Figma to Webflow execution. For Webflow speed optimization, I improve Lighthouse Performance by +25 to +50 points, reduce Webflow page weight by 30% to 70%, improve load time by 1.0 to 3.0 seconds, improve LCP by 0.5 to 2.5 seconds, and keep CLS under 0.10 for better layout stability. I optimize Webflow images, reduce unused assets, simplify Webflow interactions, clean front-end structure, and improve performance before launch. For Webflow CMS and Webflow Editor setup, I configure collections for blogs, case studies, listings, directories, team pages, service pages, and landing page templates. This helps non-technical teams update content faster, reduce developer dependency by 40% to 80%, and cut Webflow CMS publishing time by 60% to 90%. For Webflow SEO, I complete meta titles, meta descriptions, H1 to H3 heading structure, image alt text, clean URLs, 301 redirects, sitemap checks, indexability review, and launch settings. I also connect Webflow forms with CRMs, Airtable, Make, Zapier, and internal tools to reduce manual admin work by 50% to 90%, reduce duplicate entries by 60% to 95%, and improve lead routing workflows.
