Project details
As a top rated mobile app developer, I focus on learning app development and education app development, creating scalable solutions for Android and iOS using Flutter, React, React Native, Swift, Kotlin, Java, Jetpack Compose, Compose, WatchKit, and SpriteKit. As an iOS developer, Kotlin developer, and python developer, I build apps with progress tracking, interactive lessons, and multimedia features, also supporting Apple Watch and Android TV app learning tools.
My experience as a full stack developer, backend developer, web developer, and data scientist allows me to create strong backend systems with Laravel, Django, Node, JavaScript, Firebase Analytics, React Firebase, Firestore, Synology, Ceros, and automated flows like upload products. I also use machine learning, QA testing, and optional blockchain for smarter learning experiences.
With skills in mobile app design, web design, web designer workflows, logo design, illustrator, branding, WordPress, Shopify, and Semrush, I deliver polished educational apps that improve user engagement and knowledge retention.
