Full-stack engineer with 5+ years of experience building and maintaining enterprise web applications. My core strength is native PHP with solid experience in MySQL, HTML5, CSS3/SASS, and JavaScript. I can lead projects end-to-end—from requirements and architecture to delivery—and I'm comfortable working with frameworks like Laravel and React when needed.
