Custom App PrototypeAnder Sanjuan
Design and build custom web app prototypes using no-code tools like Bolt AI—fast, responsive, and intelligently crafted. Whether you need a productivity tool, internal dashboard, focus timer, or a unique idea brought to life, I deliver apps that look great and work even better.
With a strong foundation in both UX design and logic engineering, I focus on building clean, modern interfaces backed by smart, dynamic behavior. From timer flows and conditional automations to responsive layouts and light/dark mode, every detail is designed for real-world use.
