A web application for sizing a solar PV solution based on the customer’s energy requirements. Users can enter their daily electricity needs and duration of use on the front end, such as fans, air conditioners, and lights. Then the application suggests a solar PV solution, including the panel array, battery bank, inverter size, wiring, and other electrical components required for installation. As the full-stack developer, I built the front end, serverless back end, automated unit testing, and UI design.

Deliverables
• React Native mobile and React web front end
• Test-driven sizing algorithm development using Jest and JavaScript
• Serverless back end using AWS Cognito, AppSync API, Lambda, DynamoDB, SES, S3, CloudFormation, CloudWatch, and more
• UI design using InVision App

• Ionic (Angular) front end
• In-app purchases
• Published to Google Play and the App Store

A mobile notifier app for the NED University of Engineering and Technology allows university administrators to broadcast notifications to teachers and students. These notifications can include text, images, files, lists, links, and more. As the full-stack developer, I delivered the front end, REST API, unit testing, and UI design.

Deliverables
• Ionic (Angular) front end
• Push notifications
• Node.js REST API
• MongoDB database
• Published to Google Play and the App Store
• UI design using InVision App

I was responsible for performing detailed quality assurance on this app - list down all the glitches, any missing validations, UX analysis, etc.

The required output was to create a thorough document with all my findings, along with reproducible steps for each result.

A Unity3D game that challenges your memory to remember colors - like a "Guess Who Card" game.

This was the first app I published on the Android store Google Play back in 2015. I was interested in how games are developed and decided to design and develop a simple game using Unity3D and publish it to Google Play.

This is a sign-language-to-voice (and vice-versa) translator, developed in Unity3D using Kinect.

It consists of two modules:

1. Dictionary module: A mobile application that converts text/voice into sign language (text-to-sign dictionary). A rigged 3D model performs the conversion. We created a database of 30 3D-rigged gestures, including 78-word variations. The application can take a sentence as input and understand synonyms; then, the 3D model performs the corresponding gestures flawlessly. The sole purpose behind developing this app is to replace a human translator with an automated one.

2. Distant communication module: This module attempts to replicate the existing phone call system for hearing impaired people who use sign language instead of voice as their mode of communication. This module takes gesture input using a Kinect device to send the gesture to a gesture recognizer, translating it into text. This text is then sent over a Wi-Fi connection to a recipient device. If the recipient is also hearing impaired, the received text is sent to a gesture synthesizer that outputs a series of gestures played back by a 3D rigged model.

It is based on a hypothetical book shop called Book Panda, where you can purchase books online after reading reviews by other customers.

Sastaticket.pk consulted me, Pakistan's leading online travel agency, for Stripe integration in their official website using Stripe API without using Stripe UI elements. The website is built on React and has a server written in Python.

I created a web and mobile application for BackTable, a community-driven, in-depth knowledge base for all things interventional radiology, covering tools, techniques, and expert guidance on more than 30 interventional radiology procedures.

Here is a list of features that I implemented:
• Create a catalog of devices.
• Add a new device.
• Rate or review a device.
• Post a question about a device.
• See what ratings or reviews a device has received from other physicians.
• Invite people to BackTable.
• Edit a physician profile.
• View a physician profile and their activity (devices, reviews, and questions) on BackTable.
• Login and signup.

Drrops is an artist-owned platform connecting creators with their fans at live events.

Here is a list of features that I worked on:
• The new "Happening Now" feature will reduce the check-in to just a few seconds.
• The "Universal Link" check-in workflow will allow fans to check in with a QR code.
• The "Performance Mode" cloud setting allows us to deploy more resources for major shows/tours and reduce load times.
• Many UI and performance tweaks like the passes tab, account deletion, optimizing video playback in the collection, and more.
