CellPickerView is an iOS library written in Swift that enables the user to select from multiple options through a smooth UX. The library is very easy to use and integrate. The library is distributed through Cocoapods.

Isharah is an open-source project that aims to help the deaf community. We built an isolated sign language (separate words) classifier and a continuous sign language translator using deep neural networks. We have also created an open-source forkable website that provides an online dictionary and an interface to practice sign language on. The website enables you to contribute to an open-source sign language dataset.

I contributed to an open-source Android library. The library enables you to implement a custom progress bar in a few lines of code. The progress bar can be updated so that it increases or decreases.

Carpooler is a ride-sharing iOS app that organizes carpooling for events. You sign up for carpooling for a particular event, and whether you are driving or not the app matches you up with someone to decrease the number of vehicles on the road and also gives you a fun riding experience.

An open-source Android library that is written in Java. Android has a native count-down timer, but no stopwatch. This library has the easy client use of a stopwatch that can be swiftly integrated into a project.

Hepta is an open-source iOS game written in Swift. The mission is to swipe the ball in a direction such as to reach the hole all the while evading any obstacles in the way and with the use of aiding blocks.

I contributed to a very useful open-source Android library. The library enables you to quickly implement custom tab layouts in just a few lines of code. The library has a super helpful utility that allows you to use views with the TabLayout instead of fragments. That enables you to use the SmartTabLayout within a fragment without nesting fragments. I fixed some bugs with the utility. I implemented a listener to notify observers when the views are ready to prevent the crashes that happened when clients call the views too early.

An open-source compiler written in C/C++.

Smart Home is an embedded systems project. It is a home automation and security system made with AVR microcontrollers. Everything in the house is controlled automatically depending on the preferences of the user. Also the user can manually control his house with a phone call— where a DTMF is connected with the microcontroller that can interpret the call.

BizCollab is an iOS B2B app that connects small businesses together to make collaborations. Small business owners can buy products that they need from other small businesses that sell them primarily. Thus eliminating the middle guy. The app has won an award by AngelHack.

An implementation of Tic-Tac-Toe in Java using a Swing library for the UI. The game is made with MVC design pattern.

I created complex C data structures on this project. SparesStringArray is an optimized data structure to store strings. The data structure is the best when it comes to saving memory space. SparseStringArray uses c-pointers to store a bitmap of booleans that correspond to whether a given string is stored or not.

I wrote a few solutions to problems and implemented some algorithms in C++—including a page-rank algorithm, Sierpinski Triangle, and Priority Queue.
