Why work with me I’m a front-end developer passionate about building clean, intuitive, and performant user interfaces — while also integrating automation and AI to make web tools smarter and more efficient. Over the past three years, I’ve helped clients create modern, responsive front-end applications that connect seamlessly with automation backends, streamlining workflows and turning complex processes into simple, user-friendly experiences. I specialize in JavaScript (React) and modern front-end practices — from component-driven architecture and state management to design systems and API integration. I also use Python and C# for building automation layers and AI integrations behind the scenes. My projects often involve using AI to extract and structure data (from images or documents) and then presenting it in interactive web dashboards or tools that make data accessible and actionable. I write clean, maintainable code, value strong UI/UX design principles, and focus on making every product both functional and enjoyable to use. What I offer Modern front-end development with React and Tailwind / Material UI AI- and automation-integrated web tools that connect visual interfaces with smart backends Pixel-perfect, responsive design optimized for performance and usability Custom dashboards and admin panels that turn complex data into clear insights Scalable, maintainable architecture ready for future growth Collaborative, detail-oriented workflow with clear communication and ongoing support If you’re looking for someone who can blend front-end expertise with automation and AI capabilities to deliver polished, intelligent web applications — I’d love to help bring your project to life.

I don't just build websites - I build automated revenue engines. For 10+ years, I've helped eCommerce brands scale via high-converting Shopify builds, Klaviyo retention, and custom AI automations.

Klaviyo Email Marketing: Deployed advanced lifecycle flows and segmentation that consistently drive 27% of total store revenue. AI Automations: Engineered custom workflows saving clients 20+ hours/week — content generation, chatbots/AI agents, RAG/data pipelines, and API/workflow orchestration. Automated SEO: Fully-automated SEO systems powered by real Google Search Console data to rank high-opportunity keywords without manual analysis. Ads & Web Dev: Improved Meta Ads ROAS from 2.1x to 4.3x, and developed 100+ WordPress/WooCommerce sites with 40% faster load speeds. Beyond client work, I am an eCommerce operator running my own stores. I test every theme optimization, Klaviyo flow, and AI script with my own budget first - so you get strategies proven to drive real sales, not theory.
