Implementation

Architecture

CQRS/ES: According to Martin Fowler, CQRS stands for Command Query Responsibility Segregation. It's a pattern that I first heard described by Greg Young.

Domain Driven Design (DDD) Bounded Contexts

Core: Optimal Asset Allocation
Supporting: Saving and Investment
Generic: Ledger and Pricing (external)

Ledger Domain - Entity-Relationship

Technical Details

Client Side - Angular 2 TypeScript app packaged with WebPack and Bootstrap layout and styling:

Angular 2 and TypeScript for client-side code. [Angular Universal] (https://github.com/aspnet/JavaScriptServices) for faster initial loading and improved SEO, your Angular 2 app is prerendered on the server. The resulting HTML is then transferred to the browser where a client-side copy of the app takes over;
Webpack for building and bundling client-side resources. In development mode, there's no need to run the webpack build tool. Your client-side resources are dynamically built on demand. Updates are available as soon as you modify any file;
Bootstrap for layout and styling. In production mode, development-time features are disabled, and the webpack build tool produces minified static CSS and JavaScript files.

Server Side - ASPNET Core backend with a restful API using Kestrel Web API Controllers:

ASP.NET Core and C# for cross-platform server-side code
CQRS/ES architecture using CQRSLite
Bitcoin support using NBitcoin
Persistence layer using MongoDB
