System: Assembler's Factory Floor Time-Tracking App

Client: Whippendell Marine

Technologies: Raku, CRO, Template::Nest, jQuery, CSS, MySQL

Problem: Create an application that interfaces with the company's existing Teamwork-based project management system and enables assemblers to log time spent on jobs - with design according to client spec.

Solution: A set of "Element" modules were created in Raku which inherited from a base module responsible for making calls to the Teamwork API. Syncing of local application data was accomplished with an independent daemon looping over and caching necessary user and project information in a MySQL database. Server-side rendering created dynamic content with Template::Nest, and the front end assembled HTML chunks delivered from the backend with jQuery. The system was designed to be deployed to Android-based tablet as a PWA app.

System: "SuperGraph" Native Android App

Client: John Adams Ltd.

Technologies: Java, Android, XML

Problem: The app had been removed from the Google Play Store due to a reported stability issue. There were also problems with accessibility of some buttons on smaller screens.

Solution: Several minor fixes were implemented including build parameter and file format updates, and layouts were corrected to make missing buttons visible on smaller screens. Updates were tested on multiple emulators using Android Studio. The app was successfully redeployed to the Google Play Store, and a report produced detailing the changes.

System: Distributed web-automation application simplifying tasks on a public sector ecommerce portal

Client: MePATool

Technologies: Perl, Javascript, Mojolicious, Hypnotoad, SQL

Problem: The workflow required for public sector ecommerce in a particular jurisdiction can slow down business.

Solution: 7 subsystems have been created and are maintained by Virtual Blue, including client executables, API, Web Admin and web-automation processes. Multithreaded headless Chrome instances are controlled via a custom process management system. Rendering browsers tend to be memory hungry which is one reason the system is distributed across several servers, in order to cope with traffic spikes. Recently very low error rates have been achieved.
