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

Multiplayer Statistics Dashboard Website for Battle for Wesnoth

I created a dashboard web application for The Battle for Wesnoth, a free turn-based strategy game.

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.

Algorithmics and ANALI Bacolod

I developed a web application for a franchisee of ANALI and Algorithmics, both children's STEM education platforms, to facilitate registrations for Introductory Lessons and Assessments.

Technologies Used

Details

• At the beginning, I created a mockup using Figma to set expectations with the client and make sure we were on the same page.
• There was no infrastructure or anything in place when I began, so I really had to go fullstack and set everything up from scratch. Within Google Cloud, I carefully selected a cloud solution that would not incur regular costs for the client.
• I used App Engine for hosting, Identity-Aware Proxy for authentication, and Firestore for the database. I made sure the client understood basics of how to manage the infrastructure of the application, such as how to go into the Google Cloud and Firebase Consoles to view settings and data.
• The usage of Flask allowed me to easily integrate the development of the backend and frontend, especially with the tools in its ecosystem like Jinja and WTForms.
• As a solo dev, Bootstrap was great in saving me time ensuring the front end was responsive and aesthetically pleasing.
• I made two variants of the application, the difference being the color scheme and some of the words used, to match the two different brands, Algorithmics and ANALI, of the client.
• The forms employ client-side and server-side validation and protection against cross-site request forgery.
• The web application has pages that give feedback such as error pages and success pages.
• The web application has functionality for the client to view and download the data of the registrations.

TTS Cards

I created a desktop GUI application called TTS Cards that allows you to convert cards in Tabletop Simulator, a digital platform for creating and playing board games and card games, into printable PDFs. Perfect for print and play of fanmade content and expansions, as well as for boardgame developers making prototypes, or for making proxies.

Technologies Used

Details

• I used TkInter for the GUI and Pillow for image processing.
• From consulting online and looking at the Tabletop Simulator object files, I was able to determine the format of the files and how to extract the card images. I employ recursive search to find all the cards in the object files.
• I made the app behave properly on the PC operating system, such as by saving the output files in the user's documents folder, and having a proper setup to have the app installed in the correct directories.
