AI Evaluates Pi Illustrations

Date: 13/07/2025, TWG

Introduction

When your buying software, especially large scale software its very difficult to determine the quality of work that you are buying into. Every supplier will tell you that there software is high quality, scalable, and well designed, but often the opposite is true, so how can you evaluate this to drive confidence and certainty.

Evaluating large applications like Pi is typically been a time-consuming expensive and often individually opinionated process, so TWG turned to AI to get the job done.

Microsoft acquired GitHub in 2018 and this is now the largest code repository in the world with 420 M code repos [GitHub Numbers, Feb, 2024] and with over 100 M developers [GitHub blog Jan 2023]. In 2021, Microsoft added AI, with GitHub Copilot which was one of the first widely adopted AI-assisted software development tools. Copilot now supports an inter-changeable array of AI models, including Chat GBT-4.1 and Claude Sonnet 3.7 which are both code generation and code review expert systems.

Given Claude AI and Chat GBT are expert code systems, integrated into the Worlds largest code repo, the team at TWG agreed that this would be the best place to get expert, non-opinionated code quality assessment, so we set about asking AI to critically evaluate Pi's code base and we were delighted with the results.

Pi Illustration Engine: A Unified AI Expert Assessment

In combined reviews by leading AI systems (Chat GBT-4.1 and Claude Sonnet 3.7), TWG Solutions’ Pi illustration calculation engine and domain model were scored as outstanding, reflecting a mature, enterprise-grade foundation. This summary distils their findings for prospective customers, highlighting Pi’s architectural robustness, domain fidelity, and software craftsmanship.

Architectural Excellence

• Modular & Layered: Clear separation between the core simulation engine and financial domain logic ensures maintainability and ease of extension.

• Flexible Event Framework: Discrete‐event scheduling with prioritised queues supports complex, time-based scenarios without sacrificing clarity.

  
  

Rich Domain Modelling

• High Domain Fidelity: Entities like charges, policies, and portfolios encapsulate both data and behaviour, mirroring real-world financial constructs.

• Hierarchical Relationships: Composite structures allow uniform operations across nested products, simplifying aggregate calculations and reporting.

  
  

Masterful Use of Design Patterns

• Command & Rollback: Two-phase commit/rollback guarantees transactional integrity, crucial for reversible financial operations.

• Strategy & Observer: Pluggable calculation strategies and event notifications enable custom extensions without core changes.

• Composite & Template Method: Reusable algorithm frameworks and uniform entity operations drive consistency across the codebase.

  
  

Performance & Scalability

• Efficient Evaluations: Lazy computations, caching, and short-circuit logic minimise overhead, keeping illustration runs lightning fast.

  
  

Extensibility & Maintainability

• Interface-Driven Growth: New event types, financial products, and calculation strategies plug in cleanly via interfaces and base classes.

• Clean Code Practices: Consistent naming, encapsulation, and self-documenting structure make onboarding and evolution straightforward.

  
  

Robust Transaction Management

• Nested Transactions: Full rollback capability and isolated event states ensure financial accuracy even under complex operation stacks.

  
  

Comprehensive Testing Support

• Natural Test Seams: Interfaces and event boundaries allow unit and integration tests to isolate behaviours, boosting confidence in quality.

  
  

Why Buyers Can Be Confident

Pi’s combination of architectural rigour, deep domain expertise, and software engineering best practices delivers:

• Reliability: Transactional guarantees and mature event handling minimise risk.

• Flexibility: Modular design lets you tailor illustrations to evolving product requirements.

• Performance: Optimised core routines keep end-user experiences responsive.

• Maintainability: Clean code and documented patterns reduce long-term support costs.

Backed by outstanding AI expert system score, Pi stands as a proven, future-ready platform for sophisticated pension illustrations and beyond.
