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:  Specific details are protected by NDA. However, this system - developed over a number of years - involved creation of a unique architecture utilising LLM technology in a novel way. 

Client: NDA Protected

Technologies: Llama3-70B (and other LLM and ML models), vLLM, Python, Transformers, Algorithms

Problem: NDA Protected - but relates to asset price prediction

Solution: The innovative approach involved making an analogy between the "fuzzy" system we needed to model, and certain more rigorously defined mathematical/physical systems. Specific details are NDA protected. For the implementation we took advantage of per-hour cloud GPU rental to perform the necessary heavy processing as cost-efficiently as possible. 

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.
