SQUARE - greenfield application for qualitative and quantitative analyses and commenting on financial data. Currently, it represents the highly configurable product, applicable on arbitrary datasets and arbitrary combinations between them. Applicable also as a reconciliation tool. It was developed following scrum, feature-driven, and lean software development and clean code principles.
• Oversaw architecture/implementation of back-end components for the SQUARE application, including, but not limited to, RESTful HATEOAS API, MSBI integration with OData service, OData client/services, custom application workflow, application business services, and DAO layer, and integration
of SharePoint RESTful API and other third-party APIs used by SQUARE application.
• Crafted simplified solutions for several business cases by abstracting/merging data models while expanding configuration options that saved implementation costs per data source after formalizing data processing.
• Presented patterns, code review, static code analysis, unit and integration testing for the SQUARE application while driving code optimization and profiling
 
 • Optimized technology stack to deliver enhanced support of all non-functional requirements and architectural patterns/constraints and a more advanced DevOps toolset.
• Riskassessmentandcoordinationofsoftwarereleasesandcomplexrefactoring and upgrades (with Strangler pattern).
• Last but not least supported the team in solving engineering problems and improving code quality and engineering practices.
