# Haider Ejaz > Software Engineer | Full-Stack Web Developer | Frontend Specialist (React.js, Next.js) | Backend Developer (Node.js, Express.js, MongoDB, AWS) | JavaScript, TypeScript, PHP, Python | Shopify & WordPress Expert Location: New York, New York, United States Profile: https://flows.cv/haiderejaz 👋 Hello! I’m Haider Ejaz, a Software Engineer and Full Stack Web Developer based in NJ, offering hybrid and on-site services across New Jersey and New York. As a curious kid who used to disassemble computers just to understand how the parts fit together, my path toward coding was a natural progression. My journey began with a small project: I created a simple website for my uncle's business. The joy of seeing my code come to life, enhancing utility and ease-of-use for people, was immeasurable. In college, I majored in Computer Science and landed an internship with Extreme Commerce, a fast-growing ed-tech firm. There, I was part of a team that designed and developed a website front-end for their online courses business, increasing their online sales by 37% within the first quarter of launch. After graduation, I joined Extreme Commerce full-time, where my team and I built tailored applications that boosted user retention rates by 25%. I then moved on to Excellence Delivered, where I advanced from Web Developer to Senior Web Developer, working on React.js, PHP, Node.js, WordPress, and Shopify projects. At Full Stack Labs, I contributed to high-profile projects for clients such as Uber, Siemens, and Ekso, developing scalable full-stack solutions. Later, through Half Code, I expanded into Shopify and e-commerce development, customizing themes, integrating APIs, and optimizing global Shopify stores for performance, SEO, and conversion rate improvements. My portfolio includes work on platforms like Mejuri.com, NerdWallet.com, Zudo.co, Borntough.com, and MylarLegends.com, where my contributions enhanced user experiences and accelerated business growth. My expertise spans frontend (React.js, Next.js, Tailwind CSS), backend (Node.js, Express.js, PHP, Python), databases (MongoDB, MySQL, PostgreSQL), and cloud/automation (AWS, Docker, CI/CD). I’m particularly skilled in Shopify development, including Liquid, Hydrogen, app integrations, and speed optimization, along with SEO and CRO strategies that directly impact revenue. Outside of work, you’ll find me at the gym, pushing my limits and striving for personal bests. Just as I tackle complex coding challenges, I approach my fitness journey with discipline and focus. The adrenaline rush from lifting weights or conquering a challenging workout mirrors the thrill of solving intricate coding puzzles. 📧 Always open to connecting about new projects, web development challenges, or exploring opportunities where technology and creativity meet.
