Engineered a multi-tenant SaaS platform enabling Shopify merchants to build custom storefronts without coding. Developed using Next.js, React, and MySQL, with Cloudflare's edge infrastructure (Workers, KV, R2) for high

• • Drove the strategic pivot to an AI-first page builder experience, collaborating closely with CTO and CPO to define the product direction. Integrated natural language processing to generate pages from text prompts and external resources (images, URLs), implemented semantic search across the section template library to surface relevant components for both customers and AI agents, and built AI-powered content generation capabilities.

• • Architected and implemented a custom third-party resource loader, enabling seamless integration of external scripts, widgets, analytics pixels, and dynamic data into the templating engine—expanding platform extensibility for merchant customization.

• • Mentored engineering team members, improving code quality standards and unblocking developers on complex technical challenges, fostering a culture of knowledge-sharing and technical excellence.

• • Contributed to major platform migrations, partnering with CTO to move from Vercel to Cloudflare's edge infrastructure (Workers, KV, R2) and from Sanity (NoSQL) to MySQL. Implemented key components and critical migration paths that significantly reduced operational costs while improving query performance, transactional integrity, and scalability in a multi-tenant environment.

• • Delivered critical platform integrations and features, including optimistic cart implementation with instant UI feedback, merchant-configurable promotional logic using Shopify Functions (free product offers), and numerous complex UI components with corresponding database migrations across the platform.

• • Re-architected the platform's dynamic templating system, enabling complex property composition from external data sources (Shopify products, collections, cart, articles). Built a flexible property system with filters, parameters, and validation rules that became foundational infrastructure for numerous platform features, including third-party script loaders and dynamic content rendering.

• • Resolved critical performance bottlenecks by refactoring React Context API implementation, eliminating unnecessary re-renders across the platform and significantly reducing Total Blocking Time (TBT). This multi-month architectural improvement enhanced merchant site performance and improved developer experience for future feature development.

• • Implemented Shopify Multipass checkout integration, resolving a critical authentication issue for key enterprise customer (Supergoop) that was blocking revenue from authenticated checkout flows.

• • Established technical expertise in React architecture and performance optimization, becoming the go-to engineer for debugging complex issues, unblocking critical features, and guiding architectural decisions across the engineering team.

• • Collaborated cross-functionally with CTO, CPO, UX team, and customer success to deliver features, provide technical guidance to customers, and shape platform architecture decisions.

• • Drove significant web performance optimizations leveraging deep expertise in React and Next.js architecture, enhancing Core Web Vitals and overall user experience across merchant storefronts.

• • Built a mobile-first e-commerce application using Vue.js and Cordova, delivering a swipeable interface for users to discover personalized outfit recommendations. Integrated with ML system that adapted suggestions based on user preferences and generated custom outfit combinations from similar products.

• • Developed a designer backoffice platform enabling the creative team to curate outfits from a catalog of tens of thousands of products sourced from affiliate networks.

• • Maintained and extended PHP API with critical third-party integrations including Shopify, Stripe payment processing, affiliate provider feeds, and machine learning recommendation engine.

• • Engineered automated product catalog synchronization system, handling daily updates of product availability and pricing across multiple affiliate providers to maintain accurate inventory for hundreds of thousands of items.

• • Managed Kubernetes infrastructure on Google Cloud Platform, handling deployments, maintenance, and reliability of production services.
