Senior C# Azure Cloud Developer

Project: Forsikrings Skifte Løsningen (Solution for automated insurance company change) 

David was hired to join an existing in-house developed project that was expected to be late. The project was an integration between internal systems and an API provided by the Danish trade association for insurance (Forsikring og Pension). Through hard work of everyone involved it was ready ahead of time.  Took a defining role in developing and architecting a microservice for automating outgoing requests for claim histories to other companies through the industrywide FSL rest API. Refactored existing functionality for automated claim history reporting for vehicles into an easily extendable solution (for other industry-product types) using the strategy pattern and implemented automated claim history reporting for accident insurance.  Facilitated and implemented event-driven best practices for robust and fast asynchronous communication using Azure Event Grid.  Gave an in-depth understanding of EF Core to in-house developers and helped them structure their code in a modular and maintainable way.  Quickly familiarized himself with the domains of insurance claims and processes for vetting potential insurance clients. Worked closely with in-house developers actively learning domain and project needs and actively teaching about the quirks and strengths of the chosen technologies and how to progressively produce even more SOLID and maintainable code.

Project:          David called out the need for and introduced End2End testing to secure mission critical product. Building the foundation and methodology for further test coverage by colleagues.

•         Identified need for automated testing and End2End testing and convinced stakeholders to dedicate time to a proof of concept

•         Implemented proof of concept of a release pipeline with End2End testing in a complex product within a month

•         Created buy-in from PO, Team lead, the manual test team, and developers to permanently change the approach to release verification

•         Handed over knowledge, experiences and identified challenges to a small team of developers when moved to a different team.

•         Used scrum and quarterly releases.

Project:          David designed and implemented numerous event driven microservices for orchestrating, importing and live updating financial data for a bond portfolio management system

•         Quickly familiarized himself with the domain of bonds and key metrics, becoming the domain expert on these chains.

•         Produced materials for teaching the domain of Bond types, markets, and key metrics to new developers.

•         On-boarded and mentored new colleagues to the team twice

•         Introduced new and old colleagues to the world of bonds 5+ times.

•         Designed and implemented 4 microservices for event driven import of financial data from 100 million to billion-dollar investment funds. Identifying and Mapping key data to internal domain models in collaboration with financial employees in New York.

•         Participated in design and implementation of the deployment and testing strategy redesign that allowed a change of release cadence from 3/week to 3/day

•         Designed and implemented automated unit, service, UI and End2End tests for all services he implemented and some older services he refactored and added functionality to or optimized runtime of.

•         “Log Ninja”, identifying and monitoring system issues across 50 live services, alerting relevant stakeholders with precise information about the nature and cause of an issue.

•         Used Kanban with multiple daily releases on the team
