ProHabit — web application for habit formation
Role: Frontend Developer
Technologies: React, Next.js, TypeScript, SCSS, React Hooks
…
Developed the frontend part of the ProHabit application, ensuring a convenient and modern user experience.
My contribution:
Development of UI components — creating responsive and reusable components (buttons, habit cards, modal windows, forms).
Responsiveness and accessibility — optimization for mobile devices, adding ARIA attributes, improving UX for users with special needs.
Performance optimization — lazy-loading components, code splitting, and memoization.
Results:
Accelerated interface loading by 30% due to render optimization and code splitting.
Ensured stable performance on mobile and desktop devices.
Increased user engagement through improved progress visualization.
