About Android Versions

A comprehensive Android API level reference built by a developer, for developers

Who I Am

Hi! I'm K M Rejowan Ahmmed, a Senior Android Developer with years of experience building mobile applications. While Android development is my expertise, I've always been passionate about exploring different technologies and building tools that solve real problems for developers.

The Problem

As an Android developer, I constantly find myself looking up API levels, checking which features were introduced in which version, and comparing Android versions for compatibility decisions. The information is scattered across official documentation, Wikipedia, and various blog posts. I needed a single, fast, and comprehensive reference that had everything in one place.

The Solution

That's why I built Android Versions- a clean, fast, and comprehensive reference for Android API levels and version information. What started as a personal tool quickly evolved into a full-stack project that showcases my skills beyond native Android development.

The goal is simple: help myself and fellow Android developers quickly find the information we need, when we need it. No more jumping between tabs or scrolling through lengthy documentation.

What This Project Demonstrates

This project showcases my ability to:

  • Build modern web applications with Next.js and React
  • Design clean, developer-focused interfaces
  • Work with backend services and databases (Appwrite)
  • Implement rich text editors and content management systems
  • Think about information architecture and user experience
  • Ship production-ready applications across different platforms

While Android is my primary expertise, Android Versions proves I'm a versatile full-stack developer who can work with modern web technologies and build complete solutions from concept to deployment.
