The Insurance Safety Consultants System was modernized, transitioning from the legacy on-premises to an Azure PaaS solution. My role involved analyzing the existing system and designing and implementing the new version, including the migration from a state-based architecture to an event-sourced architecture.

My responsibilities included:

• Conducting business analysis and gathering requirements, engaging various stakeholders throughout the entire project.
• Architecting the Azure-based solution, utilizing Azure Functions, Service Bus, MySQL Flexible Server, Azure Monitor, Azure Application Insight, Azure Storage, and other relevant components.
• Designing and implementing the front end using Blazor WebAssembly .NET 6.
• Designing and implementing the back end using ASP.NET Core, Azure Functions, and .NET 6.
• Integrating with 3rd-party providers, including LC360 and Starr, leveraging Azure Service Bus.
• Migrating data from the legacy system to ensure compatibility with the new event-sourced system.
• Establishing and implementing a fully automated CI/CD pipeline with Azure DevOps.

During my tenure at Particular Software, I had the opportunity to work with multiple customers and their projects, with a focus on developing custom-built services and integrations that involved Azure, distributed systems, messaging, and NServiceBus.

My responsibilities included:

• Managing and collaborating on work across continents, specifically North America, Europe, and Australia, with fully dispersed teams.
• Ensuring continuous engagement with stakeholders and maintaining effective communication with customers.
• Establishing streamlined processes for exploring potential product offers.
• Collecting and analyzing requirements and planning project execution.
• Collaborating with the customer success group to provide pre-sales support, POC support, and production troubleshooting.
• Conducting technical training and onboarding sessions.
• Developing and maintaining NServiceBus components in the .NET Framework 4, .NET Core 2.1 and 3, and .NET Core 5 to 6 using messaging services such as Azure Queue Storage, Service Bus, Event Grid, Event Hubs, supporting Azure Functions, Azure Web Apps, and containerized solutions.
• Implementing persistence components using Azure SQL Server, Table storage, Cosmos DB, and Blob storage.

In this project, I was responsible for architecting and implementing the back end of a cloud-native microservices-based system. This system handled data synchronization exchanged through multiple APIs and web interfaces. The project was developed entirely using the Azure stack.

My role involved:

• Interacting with stakeholders to understand and translate their requirements into working software.
• Assisting with design documentation and implementation.
• Utilizing .NET Core 3 and .NET 6 for development.
• Implementing microservices using NServiceBus.
• Leveraging Azure Functions.
• Using Azure Service Bus for messaging.
• Storing data with Blob storage.
• Managing data with Azure SQL Server.
• Securing information using Azure Key Vault and App Configuration service.
• Deploying the system using Azure Resource Manager (ARM) templates.
• Implementing automated unit testing and CI/CD using Azure DevOps pipelines and GitHub Actions.
• Employing Azure Web Apps for UI.

• Migrated the main website to .NET 8.
• Architected and implemented UserPersonalization service, building out Favorites unified experience from the ground up.
• Modernized Search back end.
• Added messaging features to the Orchestration Plane.
• Architected and implemented event-driven architecture to connect user personalization, identity, catalog services, and external music providers (Spotify and Apple Music).
