Tech Lead & Full Stack Development

VirtualZone

As the sole web developer, I was responsible for maintaining and completely migrate an old PHP-based website from scratch to modern technologies. I chose Next.js and TailwindCSS, developing a new platform that included both a customer-facing website for live bookings and an internal back-office system for managing reservations, invoices, and marketing operations. The migration was successfully completed and next I focused on exploring new features and collaborating with a growing team to redesign and scale the platform for future expansion.
