About

Flutter & Dart Developer

Hi, I'm Kareem Zaher, A freelance Flutter & dart Developer.

I graduated medical school in 2012, started working on my career as a urology intern, a urology resident then a urology specialist till 2018.

I started learning dart & flutter in late 2018 & early 2019, since then I constructed many projects from top to bottom using flutter as a frontend tool & dart in the backend.

As of 2019, I became a fulltime urology surgeon & a Freelance Flutter & dart developer @ Upwork.com

This Landing page is an attempt to learn javascript from scratch as per the requirement of the EGFWD initiative / Udacity NanoDegree Program, eventually aiming to add Angular / TypeScript to my tech stack.

I learned the basics of navigation & styling in Flutter as well as implemening many basic to mid level dart language concepts.

  • CosmoSurge Clinics App

    • In this project I implemented what I learned in dart language about API calls, Managing state in Flutter using the provider package, Advanced routing & navigation, Custom styling & creation of reusable components. It is a Doctor / Clinic Booking app with backend deployed on Oracle Cloud Network.

  • CosmoSurge Clinics Website

    • The website counterpart of CosmoSurge Clinics Mobile App with the same functionalities & deployed with Firebase Hosting. It was a good introduction to the Flutter WEB echosystem with a small introduction to HTMl/CSS.

  • ProClinic Systems Website

    • It's a landing page created with Flutter to demo ProClinic "Clinic Management Software" with links to Youtube explanation videos in Arabic, Important app features, Contact details & a downloadable link to the demo application.

    • A Marketplace for Quizzes in different subjects. Each user has a profile with a login / logout function, changing profile information & phone number. You log in, select which instructors to follow & show their uploaded quizzes, put a quiz in your favorites & purchase a quiz.

    It was a challening project overall, it consisted of 4 major parts: a Marketplace website for students, a windows application for instructors to add & customize their quizzes, a mobile android application for students to login & access their purchased quizzes with an exam mode & a study mode & finally a backend server that is 24/7 online deployed on VULTUR.

    • Created with wordpress 😅, Has my clinic contact information & working hours. Yet I recently used Flutter WEB to improve / change certain pages of the website using IFRAMES, a little hacky I know 😅 & is 100% functional & woking.

I used Provider for state management, Go_Router for routing, backend in Dart using Conduit & deployed on Oracle cloud platform.

  • Magic_Buffer Dart Package

    • Pure Dart package implementing Buffer class from [Node.js]. This package is built to let you handle reading & writing byte data &/or strings into Uint8Lists easily. The API is aimed to be identical to that of [Node.js].
