Expert-Vetted AI Architect and Engineer with 15+ years in software and 5+ years building production AI systems. I help companies design, build, and scale AI products that move beyond demos and actually work in production. My work includes AI SaaS platforms, agentic AI workflows, RAG systems, document processing, workflow automation, AI copilots, chatbots, voice AI, and LLM-powered applications using OpenAI/Claude/Gemini, Python, vector databases, APIs, and modern cloud infrastructure. I’m usually brought in when a company needs to: ➡️ Build an AI product from MVP to production ➡️ Turn a rough idea or prototype into a working system ➡️ Fix an AI system that is unreliable, slow, or incomplete ➡️ Add AI into an existing SaaS product or business workflow ➡️ Design the architecture before development goes off track ➡️ Scale a system that is breaking under real-world usage I work across the full lifecycle: product thinking, architecture, data flow, model integration, backend development, cloud deployment, and production hardening. I don’t just connect an API and call it AI. I design practical systems with the right architecture, tradeoffs, and implementation path so the product can be used, maintained, and scaled.

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.
