  • Mobile and Web App to Connect Stylists and Users

    The client wanted to develop an app to connect stylists with users, which facilitated chats between users and stylists, kept the users engaged, and had a daily updated collection of hand-chosen outfits, the users' own collection of outfits, and payment section.

    I figured out what we needed for a mobile app, a secure back-end server, and an admin dashboard with these requirements. Being a full-stack developer, I created the overall plan and built the API, chat sockets, mobile app, and web dashboard.

    There were challenges in integrating and testing all modules. I also wrote automated tests to make the modules predictable.

    The overall project was built and published in less than three months.

  • Mobile Application for a Shopping Website

    I developed a mobile app for a shopping website with a large user base for the project. The client wanted to create the app in iOS and Android simultaneously. We chose React Native to achieve it.

    I converted the design in Sketch and built it in React Native app components.

    There were challenges in tracking bugs and user's feedback. We also integrated support libraries to get input from the client within the app.

  • User Dashboard

    The project is to create a customer self-service portal for car servicing. The client wanted to allow the customers to sign up with their phone numbers and check their car service details.

    The challenging part was converting the local unorganized database to an online full-text searchable database.

  • API for a Polling App

    I worked with a team of software developers to create APIs for a polling app. The client wanted to release the app for mobile as well as web.

    My role was to select the best technologies to implement the app. I focused on libraries that are easy to scale and fast to develop.

    The client was expecting a large amount of traffic right from the beginning. I used a microservice-based back end to allow us to scale for large traffic.

  • Learning Mobile App

    On this project, I needed to update the existing POC app with an actual design and functionality. I used the designs provided by the client for the new app.

    With an existing back-end REST API, I integrated them to fetch learning module data customized to the end-user.

    It was challenging to make the app look the same on Android and iOS because of the highly customized designs.

  • Implementing Serverless Node.js Functions Using Google Cloud (Publication)
    Serverless computing is an architecture style in which the code is executed in a cloud platform where we don’t need to worry about the hardware and software setup, security, performance, and CPU idle time costs. It's an advancement of cloud computing that goes beyond infrastructure that abstracts the software environment as well. It means no configuration is required to run the code.
