Full Stack JavaScript Developer certified by the University of Pennsylvania with a demonstrated ability to craft user-centric web experiences using NEXT.js, SCSS, Node, and custom headless CMS solutions. Skilled in leveraging ES6, asynchronous coding, and functional components for efficient, dynamic programming. Proficient in precise data retrieval with GraphQL and RESTful API integration, consistently delivering high-performance applications. Recognized for rapidly learning and integrating new development languages and technologies while collaborating with clients to strategize and execute based on user stories. Passionate about optimizing deployment environments and committed to staying ahead of industry trends with responsive, mobile-first designs. ____________________________________________________________ Experience Ample – Cincinnati, OH (Remote) Full Stack Software Developer | Aug 2022 - Current Custom Component Library: Partnered with the CTO to architect and launch a custom, reusable internal component library using Astro.js, Tailwind CSS, and Contentful headless CMS. Delivered bespoke designs and animations that enhanced the user experience while substantially lowering project costs—positioning our solutions in the competitive lower-priced segment of the market. This strategic initiative unlocked new client opportunities, driving significant internal revenue growth and securing long-term retainer contracts with high-growth organizations. Enterprise-Grade Architecture: Under the mentorship of the CTO, refined expertise in designing and implementing a scalable, page-based component library system. This architecture is adopted by multi-million dollar corporations to streamline UI development, enhance design consistency, and deliver robust, enterprise-grade solutions. Innovative CMS Solutions: Leveraged extensive research and personal initiative to develop custom CMS plugins and app solutions for Contentful, significantly enhancing client UI experiences. Continuously prototyping and submitting innovative ideas to Contentful, I actively contribute to the evolution of their platform. Internationalization (i18n): Collaborated with the CTO to integrate i18n for a client’s website, delivering German and French versions through strategic CMS modifications and a custom translation utility. Enhanced user experience with automatic locale-based redirection and a cookie-driven language selection dropdown. Accessibility Automation: Developed an automated accessibility report generator leveraging A11y tools and seamlessly integrated it into the client’s GitHub CI/CD pipeline. This tool assesses site-wide accessibility by providing page-specific scores and actionable improvement suggestions, ensuring WCAG compliance. It triggers detailed reports via GitHub PR comments for streamlined review, ultimately saving money by mitigating the risk of potential lawsuits. CI/CD Quality Assurance: Integrated Cypress testing into our CI/CD pipeline, proactively catching code regressions and defects on individual branches before merge. This initiative reduced post-deployment issues and improved overall code quality. Content Migration: Developed a robust, reusable migration script to seamlessly transfer WordPress blog posts to Contentful. The solution preserved all original elements—markup, titles, videos, images, and metadata—while implementing URL redirections to maintain SEO performance. This automated approach enabled a smooth transition to a modern content model across multiple clients, significantly reducing manual overhead and potential downtime. Revolutionized Photo Gallery Experience: Enhanced a real estate client's photo galleries in 8 weeks to rival industry leaders like Airbnb and Zillow by implementing a dynamic, double-column grid layout with a bin-packing algorithm that accommodates both vertical and horizontal images without white space; integrated interactive features such as full-screen lightbox modals with mobile-first swiping to boost user engagement, mobile responsiveness, and UI aesthetics—an approach now being packaged as a reusable TypeScript npm module. Remote Collaboration: Effectively collaborates with a remote team across multiple time zones, consistently attending daily stand-ups at 6 AM local time to ensure seamless communication and continuous project momentum. ____________________________________________________________ Invene – McKinney, TX (remote) Software Developer | Nov 2021 - Aug 2022 Leveraged prior Sequelize and MySQL knowledge to quickly learn and implement PostgreSQL solutions on live software.
