I built Parsley Moving’s production service website with React 19, Vite, and Tailwind CSS 4. I integrated Firebase for the contact form, plus Mapbox Geocoding and reCAPTCHA v3.

On Zenny, a team project, I owned the entire frontend for an AI-powered monthly expense tracker, including the user app and admin panel.

Through freelance web development, I’ve built and maintained landing pages and small business websites, implementing responsive layouts from Figma designs. I’m deepening my expertise in FSD architecture and OOP design.
