Park King

I joined Mapa Web Development (MWD) as a Software Developer, tasked with providing expertise across various aspects of software development. During my nine-month tenure, together with one other junior software developer, we accomplished the development of a mobile app called Park King, which allows users to book parking slots for events such as concerts and conferences, from inception to successful deployment.

Technologies Used

Details

• Collaborated closely with a fellow software developer, who was new to the role, to develop a mobile app. We utilized Flutter for the mobile client, Python Flask for the back end, used DragonPay for payment processing, Firebase for authentication, and Firestore for the database.
• Provided all the necessary requirements for successful acceptance and deployment of the app to the Google Play Store and Apple App Store
• Orchestrated the setup of separate local, development, and production environments for controlled development and testing processes
• Implemented CI/CD pipelines using GitLab and Docker for the back-end services, achieving high test code coverage and detailed documentation
• Managed Google Cloud infrastructure, ensuring cost efficiency, permissions, and security measures

Technologies Used

Details

• I identified that there was an opportunity to create a dashboard after I saw that there was a monthly Multiplayer Activity Report that was being manually prepared and released.
• I created a proof-of-concept for the Wesnoth organization to interact with before they decided to officially adopt my dashboard.
• I communicated with other developers to get access to the database and other data I needed, to setup and deploy to development and production environments, to ask for code reviews, and to address comments and requested changes.
• I wrote clear documentation to enable other developers to understand and run the app without having to ask me personally for all the steps in the process. I included links to the official documentation for the various technologies and libraries used by the application.
• I wrote tests to help ensure quality and possibly serve as a secondary form of documentation.
