London Congestion Charge Notification App
System: iOS and Android app to provide alerts when entering the London Congestion Zone
Client: Outbound BPO Ltd
Technologies: Rust, Javascript, Cordova
Problem: Drivers in London may find it difficult to keep track of and avoid the London Congestion Zone boundary
Solution: The system takes advantage of an Open Street Maps tiling server and Cordova's Geolocation Plugin to track the user's location in London. A push notification is sent when user approaches the Congestion Zone boundary.
Distributed web automation system for public sector ecommerce
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.
