System: Stock price history pattern matching utility
Technologies: Python (asyncio matplotlib mplfinance pandas...)
Problem: Build a system which identifies stocks that are currently in the process of repeating previously observed price history patterns, based on low-high and high-low trend time intervals.
Solution: Our solution involves iterative analysis of a large large database of stocks, gathered from web sources. Price histories are divided into progressively smaller time period bins, with duration labelled the "granularity" of the iteration. The pattern of trends across bins is compared with recent price movements to identify matching segments. We then used a visualisation system based on Japanese "renko" diagrams to depict matches in an easy-to-digest format.
Note this is a bespoke system created upon request; we provided no advice on stock selection methods.
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.
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.
