Abjapp

Learn the Arabic alphabet

Date: June 2015 to Ongoing
Technologies: Version 1.0 Objective -C Core Data Version 1.2 Swift Realm Version 1.5 Swift SwiftUI UIKit Realm

As the creator of Abjapp, an iPhone application designed to teach the Arabic alphabet, I successfully developed and launched a user-friendly and effective learning tool for students of all ages.

Through a series of lessons focused on three specific letters at a time, users can progress through the 28-letter alphabet and validate their knowledge with quizzes.

In addition, Abjapp offers users the ability to practice their knowledge at any time with randomized quizzes, and provides detailed information about each letter, including pronunciation and writing techniques for different positions within a word.

The Bell

Yet another round-based, HIIT timer

Date: May 2020 to Ongoing
Technologies: Swift SwiftUI SQLite with GRDB

View on Github Download from the App Store

As the creator of The Bell —a proof of concept watchOS app for recording HIIT workouts—, I aimed to create an intuitive and user-friendly tool that closely mirrored the look and feel of the stock Workout app.

The Bell's minimalist design prioritizes simplicity, with a focus on tracking elapsed time and notifying changes with audio/haptic feedback, as well as logging completed workouts in the Activity app.

combyne

iOS application

Date: September 2020 to June 2021
Client: combyne
Technologies: Objective-C Swift SwiftUI Firebase Parse

View Website Download from the App Store

combyne is a social app where creators combine and share outfits with their friends.

Upon joining combyne, I collaborated with fellow team members to migrate a significant portion of the codebase from Objective-C to Swift, and in some cases, to SwiftUI, resulting in a more modern and efficient codebase.

I redesigned and unified the legacy messaging systems within the app, creating a more cohesive and seamless user experience across all messaging features.

I also took the lead on a quality improvement and documentation initiative, where I collaborated with all devs and the CTO across the company to identify areas for improvement and establish standardized documentation procedures.

Genesis Energy IQ

iOS application

Date: April 2019 to November 2019
Client: Genesis Energy
Technologies: Swift Firebase Azure Node.js

View Website Download from the App Store

While working as part of the mobile team at Genesis Energy, I was involved in the development of the EnergyIQ app. My main responsibilities included implementing new management features and optimizing existing ones.

During my seven-month tenure, I helped to transform the app from a simple billing tool to a comprehensive energy management platform, which included advanced features such as real-time carbon emissions tracking and usage breakdowns.

In addition, I provided valuable support to the backend team by helping to develop new endpoints to facilitate these improvements.

actiTENS

iOS & android applications

Date: December 2015 to February 2018
Client: Sublimed
Technologies: Swift Bluetooth Low Energy Realm

View Website Download from the App Store Download from Google Play

I had the privilege of working with Sublimed on the development and launch of actiTENS, a new-generation transcutaneous electrical nerve stimulator (TENS) that comprises a hardware pulse generator and a smartphone app interface.

Starting in late 2015, I played an instrumental role in getting the project off the ground and leading the design, development, and shipping of the app on both iOS and Android over the course of two years.

How Many Sleeps?

Animated countdowns for children

Date: October 2018 to February 2019
Client: Curiome
Technologies: Swift Realm

Unfortunately, How Many Sleeps? was pulled from the App Store a few years after my contract ended.

For young children, understanding the passing of time and the duration between today and future events can be challenging. To help with this, How Many Sleeps? is an app that introduces the concept of time through a fun and engaging method — by counting the number of sleeps remaining until an event.

With How Many Sleeps?, children can learn about time and eagerly anticipate upcoming events, making it an ideal tool for parents.

Genetrainer

Genetically guided fitness

Date: May 2017 to June 2017
Technologies: Swift SVG JavaScript

View Website Download from the App Store

As a member of the Genetrainer team, I developed a muscle selection module that allows athletes to add comments and notes to specific muscle groups and joints. This information can then be used by trainers and physical therapists to set personalized goals and training plans.

In addition, the module can display the level of fatigue associated with each muscle and joint after a training session is completed, and can be easily integrated into a web-centric environment.

While this project may have been small in scope, it provided me with a valuable opportunity to hone my design and illustration skills, and was an immensely enriching experience overall.

Mynöx

Join inspiring private events in small groups.

Date: August 2017 to November 2017
Client: Mynöx
Technologies: Swift Firebase

Unfortunately, Mynöx was pulled from the App Store a few years after my contract ended.

Mynöx is a unique social network that caters to private events, allowing users to host events at their place and invite friends or strangers using the app.

The app is equipped with a wide range of features, such as real-time chat, a Tinder-like interface for inviting guests based on specific criteria, a notification center to stay up-to-date on event updates and join requests, as well as Facebook integration for finding and inviting friends.

I built upon the previous Material Design mockups provided by the client and tailored them to fit the iOS design language, ensuring a seamless user experience.

Instructions

Coach marks builder

Date: October 2015 to Ongoing
Technologies: Swift

View on Github

Instructions is a Swift-based open source iOS library that facilitates the display of coach marks. Its simple implementation and extensive customizability make it a highly useful tool for developers.

This library was originally derived from previous work, and has been ported to Swift and further enhanced to make it available to a broader audience.

ink, a narrative language developped by inkle Ltd.

I fell in love with ink back in 2017 and have been actively contributing to the ecosystem ever since. Here are a few of the projects I've worked on.

inkjs

JavaScript/TypeScript implementation of ink

Technologies: JavaScript TypeScript

View on Github

inkjs is an open source project created and maintained by @y-loshe. I'm a regular contributor to the project, which closely track the state of the original C# library.

inkgd

GDScript implementation of ink

Technologies: GDScript

View on Github

In 2018, I started a project called ingkd, which is essentially a complete port of the ink runtime in GDScript - Godot's primary programming language. At the time, Godot didn't have full support for the mono runtime.

Ink Language Server

An implementation of the Language Server Protocol for ink

Technologies: C# TypeScript

Language Server on Github VSCode extension on Github

In 2018, I initially attempted to implement a language server using TypeScript. However, I decided to abandon that early attempt and opted instead to build the language server directly into inklecate, ink's compiler.

The current version is still a work in progress, but I'm excited about this opportunity to learn and have fun while working on a Language Server Protocol implementation.

Ink TMLanguage

A Textmate grammar

Technologies: YAML TypeScript

View on Github

A grammar bringing advanced syntax highlighting in any editor supporting Textmate grammars.

Sophisticate

Clean SVGs and use them in interactive web pages

Technologies: TypeScript

View on Github

Sophisticate has been archived and is no longer maintained.

Sophisticate is a handy JavaScript tool that I frequently use to tidy up and add appropriate metadata to the output of vector editors. The resulting SVGs are usually untidy and don't have suitable classes or IDs, making them unusable once they're included in an HTML document.

Sophisticate includes various modification rules and can also run SVGO to further clean up SVGs. As I work with SVGs regularly, this small utility saves me a considerable amount of time.

Daz Studio, a 3D scene creation and rendering application developped by Daz Productions, Inc.

Autodazzler

Batch renderer for Daz Studio

Technologies: JavaScript

View on Github

Autodazzler has been archived and is no longer maintained.

Autodazzler is a script written in ECMAScript 5, designed to automate the rendering pipeline of Daz Studio.
