AI-Powered Ecommerce Expert | BigCommerce, Klaviyo & UX/UI Are low ecommerce conversions, weak retention, poor email performance, or a frustrating customer experience holding back your growth? We build AI-powered ecommerce systems that help brands increase conversions, automate customer journeys, improve retention, and operate more efficiently. You are not hiring a developer who occasionally uses AI. You are getting an experienced ecommerce team that combines: • AI development and automation • BigCommerce development • Klaviyo email marketing • Conversion-focused UX/UI • Ecommerce strategy and optimization Backed by 20+ years of ecommerce experience and 500+ ecommerce and UX/UI projects, we use AI throughout the customer journey—from product discovery and personalization to support, email marketing, conversion analysis, merchandising, and internal operations. HOW WE USE AI IN ECOMMERCE AI should do more than generate content or add a basic chatbot. We help ecommerce brands use AI to: • Personalize product recommendations • Improve onsite search and product discovery • Automate customer support • Create smarter customer segments • Improve email targeting and lifecycle marketing • Analyze customer behavior and conversion issues • Automate repetitive ecommerce operations • Build AI assistants for internal teams • Connect AI models with ecommerce and business systems Every AI solution is built around a practical outcome: increasing revenue, reducing manual work, improving customer experience, or helping your team make faster decisions. BIGCOMMERCE DEVELOPMENT Your BigCommerce store should do more than look professional. It should convert visitors, improve product discovery, support retention, and scale with your business. We help with: • Custom BigCommerce development • Theme and headless ecommerce development • Online store customization • Product page and checkout optimization • Mobile and responsive design • Site speed and performance • Search and product discovery • AI recommendations and chatbot integrations • Custom functionality and API integrations • Ecommerce conversion optimization We identify and fix the issues affecting revenue, including poor mobile usability, high cart abandonment, confusing navigation, weak product pages, and slow performance. KLAVIYO EMAIL MARKETING & AUTOMATION Traffic alone does not create a profitable ecommerce business. Long-term growth comes from converting subscribers, recovering abandoned carts, and increasing repeat purchases. We build Klaviyo systems using customer data, automation, segmentation, and AI-assisted optimization. Services include: • Klaviyo setup and strategy • Email campaign design and management • Welcome, abandoned cart, browse abandonment, and post-purchase flows • Customer retention and win-back campaigns • Predictive segmentation • Personalized email experiences • AI-assisted content, testing, and optimization Your Klaviyo system is built to recover lost revenue, improve customer lifetime value, and turn more subscribers into repeat customers. CONVERSION-FOCUSED UX/UI A modern-looking website is not enough. Customers leave when navigation is confusing, product information is unclear, or the mobile experience creates friction. Our UX/UI work combines customer behavior, ecommerce usability research, conversion strategy, and AI-supported analysis. Services include: • Ecommerce UX/UI design • Website redesign • Mobile-first design • User journey optimization • Wireframes and prototypes • Figma mockups and design systems • Product page and checkout design • Ecommerce UX audits • Conversion-focused landing pages We create clearer customer journeys that strengthen trust, reduce friction, and make it easier to purchase. CUSTOM AI DEVELOPMENT When off-the-shelf tools are not enough, we build custom AI solutions around your business. Services include: • Custom AI applications • Generative AI workflows • AI chatbots and support systems • AI agents and internal assistants • AI workflow automation • AI model integration • RAG and knowledge systems • AI-powered search, personalization, and product discovery • Ecommerce, CRM, and marketing integrations The goal is not to add AI for the sake of AI. The goal is to build a smarter ecommerce operation that improves efficiency, customer experience, and growth. WHY WORK WITH US? • 20+ years of ecommerce and digital experience • 500+ ecommerce and UX/UI projects delivered • BigCommerce, Klaviyo, UX/UI, and AI expertise • Conversion-focused development • Research-driven UX strategy • Scalable systems built for long-term growth • Clear communication and reliable delivery Send me your goals, challenges, or project requirements on Upwork.
