Mephisto is a complete UI toolkit bundle designed to help developers build apps faster with clean, customizable, and production-ready screens. The bundle includes tailored UI systems for Gym, Booking, Digital Wallet, KYC, and Authentication apps — each crafted to deliver smooth user flows, modern layouts, and high usability across use cases.

Building the entire bundle from the ground up, I focused on customizable UI systems, theme consistency, and high-quality user experience. My approach centered on:

Creating fully modular UI components that developers can reuse or extend

Designing multiple screens per app type with intuitive user journeys

Ensuring everything is customizable — borders, colors, typography, spacing

Supporting seamless light/dark theme switching

Delivering polished, smooth, modern interfaces ready for real-world apps

Flutter (widgets, theming, animations)

Custom component architecture for reusability

Adaptive layout system for responsiveness

Dynamic light/dark mode

Customizable design tokens: colors, borders, fonts, spacing

Scalable styles for brand-specific customization

Organized folder structure for easy integration

Clean, reusable utility functions and components

Optimized for performance across platforms (Android/iOS/web)

Designed UI toolkits that are completely generic yet highly customizable, suitable across multiple industries.

Built scalable component logic to ensure theme switching doesn’t break layouts or animations.

Ensured high flexibility so developers can easily rebrand and customize the UI to match their product.

Built five full UI toolkits, each with multiple screens, forms, lists, and components tailored to their use case (Gym, Booking, Wallet, KYC, Auth).

This project deepened my experience in:

Building modular, scalable UI systems suitable for real products

Designing intuitive user flows across multiple app categories

Handling dynamic theming, brand customization, and component reusability

Creating aesthetic, polished interfaces that feel premium yet lightweight

Thinking from a developer’s perspective — making kits easy to integrate, extend, and ship to production

This experience strengthened my ability to deliver high-quality frontend apps and reusable UI libraries, ideal for clients looking for fast, clean, and scalable app UI development.
