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.

I am a Senior Next.js Developer focused on React, Node.js, and API-driven web applications. My main work is building custom web products where the frontend depends on clean architecture, reliable API integration, authentication, and real user workflows. I usually work on Next.js / React applications connected to existing backends, Node.js services, REST or GraphQL APIs, Firebase, CMS tools, and third-party integrations. I can help when you need a React developer or front-end developer who can do more than just build UI screens. I can take Figma designs, Bootstrap themes, existing prototypes, or legacy interfaces and turn them into production-ready Next.js / React pages connected to real data and backend logic. I also support full-stack Next.js and MERN-stack products when the project uses React, Node.js, Express.js, MongoDB, or a similar JavaScript-based stack. My backend work usually covers API integration, authentication flows, account logic, dashboards, ecommerce flows, admin panels, and integration with external services. Earlier in my career, I worked with WordPress, CMS-based websites, and classic web development projects. That experience helped me understand content structure, SEO-friendly pages, admin workflows, landing pages, and business websites. Today, my focus is custom development: Next.js applications, React frontends, full-stack Next.js products, SaaS platforms, ecommerce flows, marketplaces, customer portals, and web applications built around real product logic. Typical projects I can help with: - Next.js and React web application development - full-stack Next.js development with Node.js and Express.js - React developer / front-end developer work for existing products - REST API and GraphQL API integration - Firebase, Firestore, and Google Cloud Platform integrations - NextAuth and custom authentication flows - SaaS dashboards, customer portals, marketplaces, and ecommerce platforms - Strapi, headless CMS, and CMS-driven web products - Figma-to-Next.js or Bootstrap-to-Next.js implementation - frontend architecture, performance improvements, and code maintainability Tech I work with: Next.js, React, TypeScript, JavaScript, Node.js, Express.js, NestJS, MongoDB, PostgreSQL, RESTful API, GraphQL, Firebase, Firestore, Google Cloud Platform, NextAuth, Redux, Strapi, CMS integrations. I am comfortable joining an existing team, working directly with a CTO or founder, taking ownership of a product area, and moving features from backlog to release.
