John Zuriel Lowie

Built a data visualization platform for oil & gas fleet management used by 100+ operators across the US and Canada. Delivered live fleet dashboards and 15+ features using React, Next.js, and TypeScript for 6 oil & gas companies and 100+ operators, handling 20,000+ deliveries per year. Integrated LLM-powered agentic coding tools into the daily front-end workflow (e.g., Claude Code and Cursor) to speed up prototyping and deployment with maintained code quality (static analysis and testing). Refactored a large legacy front-end codebase (100K+ LOC) using SOLID principles and design patterns to reduce coupling and improve scalability. Automated design-to-code handoffs using Claude Code and a Figma MCP to extract design tokens and generate reusable components. Improved performance (Core Web Vitals) using caching, lazy loading, and bundle splitting, enhanced accessibility with semantic HTML/ARIA and keyboard navigation, and raised test coverage from under 30% to 85% using Jest, React Testing

Developed custom AEM and micro-frontend components for a global platform and helped deploy features across 30+ markets. Built and deployed 15+ features and AEM projects in 30+ countries, increasing customer traffic and new subscribers by 30%. Raised test coverage to ~80% using automated unit, integration, and E2E testing with JUnit, Jest, and Cypress. Designed and implemented a design system with 50+ reusable AEM components, Tailwind CSS, and design tokens to support large-scale rebranding with visual consistency and scalability. Implemented A/B testing for React micro-frontend components using LaunchDarkly feature flags. Enforced technical direction for critical CI/CD workflows by coordinating multiple teams and tracking work in Jira. Migrated AEM and React microservices to a new API response structure, reducing load time within 3 months. Automated an API script to remove retired URLs and eliminate 100+ artifacts in seconds. Mentored junior engineers through code reviews, pair program

Developed a Soidoh health care web application and migrated a subset of the mobile app for global clients. Migrated a web application to a mobile-first architecture using Ionic and implemented containerized builds. Implemented internationalization (i18n) by centralizing translations to reduce localization errors. Refactored legacy components into reusable components, applying SOLID, DRY, and OOP principles.
