Hi, my name is Lemon! I’m a "Design Engineer" with 20 years of experience acting as the bridge between a high-fidelity creative vision and the code that actually makes it work. I specialize in moving fast without breaking things—I've launched dozens of high-performance sites on tight timelines and even developed a few popular independent games from the ground up. While I’m a technological polyglot comfortable in Vue, Angular, or Svelte, my real heart is in the fundamentals: building simple, performant, and accessible experiences that just work. I’m an international speaker on WCAG accessibility, and I bring a "player-coach" mindset to every project. Whether I'm architecting a complex system or obsessing over the perfect UI transition, I just love turning tricky requirements into elegant, pixel-perfect experiences that help people connect.
