CHALLENGES

• Completely redesign and implement a new version of the existed project in a 6 month

• Design and implement own DSL to specify complex formulas, and build an engine to solve models of formulas supporting different financial terms and functions

• Continuously receive tons of change requests, manage the process and permanently collaborate with the client

• Custom design and Angular components

• Delayed batch data processing

• Support of Multitenant structure and complete SSO implementation

ACTIONS

• Designed multi-relational, JSON-based model structure with the support of nested formulas

• Concurrent computation engine that allows computing all models or just a part of it by applying previous results

• AI implementation to help the user build his workspace using general knowledge of his business

• Flexible multitenant approach with the support of individual branding

• Subscription management and robust security implementation

• Bue-Green deployment and complex CI/CD pipeline

RESULTS

• The application was redeveloped from the scratch in 6 months, and production release was successfully finished in 8 months including whole infrastructure preparation

• Powerful computation engine and flexible DSL make the process of adding new formulas and models very quickly with minimal development

• App performance on a very high level, with the possibility to manage more than 100 mutational requests per second

• Lightning-fast model calculations based on the parallel processing approach and asynchronous connectivity

LEARNINGS

• AI and ML algorithms to classify business models and compile the most appropriate workspace

• Custom instructions specification and executions

• Complete and End-To-End SSO solution

• Team management in an extreme situation

• Infrastructure as a code solutions & tools

• Reactive programming approaches

• Bug fixing and hot deploys on production

• Audit, metric monitoring and log analyzing
