Hello, I'm John DeMedio

I’m a front-end web developer who loves turning creative ideas into clean, accessible, and user-friendly experiences.

About Me

I’m a Senior Front-End Web Developer with over 15 years of experience creating websites that don’t just look great — they work great for everyone. I love diving into complex challenges and turning them into simple, user-friendly experiences.

I believe in coding with purpose — building experiences that are as meaningful as they are functional.

Whether it’s leading a full redesign, migrating to a new CMS, or fine-tuning for accessibility and performance, I bring a creative, problem-solving mindset to every project.

Outside of work, I love writing, video production, and pop culture.

Here’s a selection of projects I’ve worked on:

React + Vite E-commerce Store

Developed a fully responsive, front-end only e-commerce store with a vintage Old West aesthetic. Built using React + Vite and styled with plain CSS. Features include dynamic product filtering, search, sorting, quantity management, a persistent shopping cart using localStorage, and a product detail view—all optimized for user experience and accessibility.

Wordle Clone — Vanilla JavaScript

Developed a fully functional Wordle clone using vanilla JavaScript, HTML, and CSS as a standalone web application. Implemented the game logic, including letter evaluation, guess validation, and tile animations, to replicate the classic Wordle experience. Built a responsive and mobile-friendly interface with an on-screen keyboard and full accessibility support, ensuring keyboard and screen reader compatibility. Integrated dynamic loading of the complete 5-letter word list and designed the UI to provide real-time feedback, error messages, and visual cues for correct and misplaced letters. Focused on performance, usability, and code maintainability, creating a reusable, modular structure suitable for portfolio demonstration of advanced front-end skills.

AmeriHealth Caritas Corporate Website & Network of Regional Sites

Contributed as part of a front-end development team for the AmeriHealth Caritas digital ecosystem, built on the Adobe Experience Manager (AEM) platform. Developed and maintained the corporate website along with a network of regional health plan sites featured on the company’s National Footprint page. Responsible for crafting HTML, CSS, and JavaScript components, implementing responsive layouts, and establishing the visual design look and feel in alignment with brand standards. Collaborated with designers, developers, and content teams to build accessible, performant, and easily managed AEM components. Also supported the design and front-end development of the company’s intranet platform, ensuring consistency and usability across internal tools.

Aging & Diverse Website

Designed and developed the entire website for Aging & Diverse from scratch, using WordPress as the CMS. I handled the HTML structure, CSS styling, JavaScript interactivity and overall look & feel to deliver a clean, modern user experience. Built fully responsive layouts, custom components and a flexible theme to allow for easy content updates and manageability. Focused on performance, accessibility and brand-driven design throughout the build.
