I’m a senior (Upwork's top-rated) UI/UX designer and full-stack web architect with more than 10 years of experience. I’ve built complete solutions with WordPress, Shopify, WooCommerce, Webflow, Wix, PHP/Laravel, and the latest AI tools. My projects range from detailed Figma design systems and interactive prototypes to custom plugins, payment systems, DevOps, and performance improvements. HANDS-ON DESIGN & BUILD WORKFLOW: ➢ Figma: I use Figma and its AI tools like Visual Copilot, Auto Layout, Design-to-Code export, and Component Suggestions. These help me create design systems, wireframes, and developer handoffs much faster. Tasks that once took two days now only take a few hours. ➢ Lovable: I use Lovable to quickly generate full-stack React apps from prompts and Figma designs. After that, I add custom business logic, backend integrations, and production-ready features. This method works well for MVPs, admin portals, SaaS dashboards, and internal tools, all delivered in days instead of weeks. ➢ AI-augmented code review & refactoring: I use AI tools during development for code review, test generation, documentation, and performance checks. This keeps quality high and speeds up delivery. WHAT CLIENTS HIRE ME FOR ▸ WordPress: Custom Gutenberg blocks, Full Site Editing (FSE), plugin architecture, headless WordPress (WPGraphQL + Next.js), performance engineering (Redis, Cloudflare, Core Web Vitals). ▸ Shopify: Theme development (Dawn / OS 2.0), Shopify Plus, Hydrogen headless storefronts, custom Shopify apps (Remix + Polaris), Shopify Functions, multi-market localization. ▸ WooCommerce: Custom payment gateways, subscriptions and bookings, B2B/wholesale catalogues, 100k+ SKU catalogue optimization with Elasticsearch, REST API extensions. ▸ Multivendor & Marketplace: Full builds using Dokan Pro / WCFM / CS-Cart / Sharetribe. Stripe Connect split payments, vendor KYC, commission engines, escrow models, vendor dashboards. ▸ Webflow: CMS architecture, IX2 interactions, Client-First methodology, Memberstack portals, Webflow headless, Make/Zapier automation stacks. ▸ UI/UX Design (Figma & Adobe XD): Full design systems using Figma AI and Variables/tokens, component libraries, interactive prototyping, Dev Mode handoff, Storybook integration, WCAG 2.2 accessibility. ▸ PHP / Laravel: REST and GraphQL APIs, Filament admin panels, Laravel Livewire/Inertia.js, Pest PHP testing, clean SOLID architecture. RESULTS I’VE DELIVERED: ▸ Used Lovable and a custom Laravel backend to deliver a fully functional B2B SaaS MVP in 11 days. The client expected this to take three months. ▸ Built a Figma AI-powered design system with over 200 components, three brand themes, and a token pipeline in six days. This reduced front-end development time by 40% for eight product teams. ▸ Delivered a headless Shopify Plus storefront using Hydrogen and Remix, achieving a 95+ Lighthouse score and tripling the conversion rate after launch. ▸ Built a multivendor marketplace for over 400 vendors, with Stripe Connect automated payouts and Algolia search, reaching more than 40,000 monthly active users. ▸ Migrated a WordPress site with 500,000 posts to a headless Next.js setup, achieving under two-second TTFB worldwide and zero downtime during the switch. ▸ Reduced page load times by 60% on more than 10 client sites by auditing Core Web Vitals and optimizing image pipelines with WebP and AVIF formats. HOW I WORK: Before I start coding, I make sure the project scope is clear. I break the work into milestones, give clear written estimates, and keep communication straightforward. I don’t just act as a contractor or freelancer; I take full ownership of every deliverable. I look for challenges early, suggest better solutions, and ensure the results are ones I’m proud of. If you want fast, polished, and production-ready results from someone who handles both design and development, let’s talk.

Your product launches on the agreed date, or you pay $0 for that milestone. Why can I make that commitment? ✅ 29 AI products shipped, two at #1 on Product Hunt. ✅ 250k+ monthly users across them (see portfolio). ✅ Founders across the US & EU trust me to rescue, rebuild, and scale. ✅ I build to get you to launch faster and earning sooner. ✅ 3x faster to market through proven SaaS frameworks. Here's what most founders learn too late. You don't have a development problem. You have a "we built the wrong thing" problem. My job is killing that mistake before it costs you anything. I move 3x faster because I'm not reinventing the foundation every time. Every hour saved goes straight into the parts of your product people will actually pay for. Think of me as a technical co-founder without the equity conversation. Someone who has already made the mistakes you're about to make. This works best if you're: ☑️A funded startup trying to turn that raise into real revenue. ☑️A solo founder who needs an MVP in the market fast. ☑️An existing SaaS team ready to add AI without breaking what already works. ☑️A founder sitting on an AI prototype that's ready to become a real product. Probably not the right fit if: ✘You need the cheapest developer on Upwork. ✘You want someone who builds what you say without telling you when you're wrong. ✘You need a demo, not a product. I'm not the cheapest developer here. The bet at the top is why. 𝐒𝐞𝐧𝐝 𝐦𝐞 𝐲𝐨𝐮𝐫 𝐢𝐝𝐞𝐚 𝐨𝐫 𝐢𝐧𝐯𝐢𝐭𝐞 𝐦𝐞 𝐭𝐨 𝐲𝐨𝐮𝐫 𝐩𝐫𝐨𝐣𝐞𝐜𝐭.
