Number One-ranked ADHD Management App
A React Native-based cross-platform mobile application to manage Attention Deficit Hyperactivity Disorder (ADHD). I worked as a senior React Native developer. While working on this project, I fixed the custom-written React Native bridge for native SDKs, implemented a notification module to manage remote and locally scheduled notifications, and implemented the new home screen interface involving A/B testing. I also set up a multi-firebase environment for both iOS and Android to test features separately on staging and production without affecting one another.

The Official Healthed App – Australia’s Most Popular Seminars and Learning Resources for GPs
A React Native-based cross-platform application to provide popular seminars, events, audio, and video materials for Australian GPs. I worked on the existing project using the old React Native version (0.61) with classes and other libraries. It was crashing on the latest Android and iOS devices, so I upgraded React Native and all other incompatible libraries to fix crashes and critical bugs to improve the UX. I fixed all the bugs reported on Apple and Google Store reviews, specifically audio and video player issues.

I also improved the monitoring side of the mobile app by integrating Google Analytics for usage tracking, Sentry for monitoring issues and crashes, CodePush for deploying over-the-air (OTA) updates, and Firebase for push notifications.

Mobile App and Management Dashboard For Sharjah Education Council (UAE)

A React Native-based cross-platform app developed for Sharjah Education Council (UAE). The application allows users to apply for different kinds of awards by the Ministry of Education and provides users access to different educational materials. I worked as a full-stack engineer and built the back end and mobile app from scratch. I developed the back end using Node.js, PostgreSQL, AWS, and Strapi as a management dashboard. For developing the mobile app, I used React Native. The mobile app has advanced features such as audio and video plover air updates, reporting bugs as they happen, and more.

Bizzenger | Deals and Coupons Mobile Application For Customers and Merchants
Bizzenger is a React Native-based powered cross-platform application to make places easier to find for customers and to attack new customers quickly for merchants.

I worked as a React Native team lead. The app was noticeably slow in performance and had a lot of bugs in the UI and logic. I changed the app's architecture and led a team of three React Native developers.

My contribution:

• App performance got improved significantly and user experience became much smoother.
• Added Merchant-related features into customer application and made it universal for both customers and merchants.
• Fixed all critical crashing issues and implemented a module to prevent and report crashes.
• Added internationalization (English, German, Turkish, Korean and Russian).
• Set up native and JavaScript side error tracking using Sentry.
• Automated App Store and Play Store deployments using App center CI/CD.
• Added over-the-air (OTA) update to fix critical bugs using CodePush.
• Revamped the design of the application completely.

Viewy Real Estate Mobile App - The New Way to See Every Property As You Pass By It
A React-Native-based cross-platform mobile application. I worked as a senior React Native contractor. I implemented firebase remote notification and Notifee in local notification modules. Moreover, I fixed the bug that crashed the mobile app and other logical issues.

To be able to push custom-scheduled notifications to customers, I integrated the service. This enabled us to track customers' activities and push custom offers to a single customer or specific segments of customers. I also worked on the back end to fix the issues on the AWS Lambda function and DynamoDB. I also resolved the DNS and domain redirection issues.

Auth0 Guardian Library For React Native
In one of the projects I was working on, I had to integrate Auth0 Guardian into a React Native project to support multi-factor authentication (MFA).

Auth0 was not supporting React Native, so I had to build a React Native bridge between Auth0 Guardian Java and Swift libraries. I created this library from scratch and open-sourced it. It helped some folks looking for solutions in the React Native community.

i18n Translations Extractor From Google Sheets
While working in multi-lingual side projects or startups, one of the many problems is supporting translations for multiple languages. There are great services like Lokalise, but most of the time, you need something free, familiar, and quick to add translations.

I used Google Sheets and a custom parser that extracts translations from Google Sheets into JavaScript code to solve this problem. You can use all the sweet features of Google Sheets, from real-time collaboration to comment.
