This integration leveraged Azure Logic Apps and Power Automate to automate business processes, enhancing operational efficiency and ensuring consistent data flow between Dynamics 365 and the SmartGov platform for improved service delivery.

Set up continuous integration and deployment (CI/CD) pipelines in Azure DevOps, using GitFlow for version control and code collaboration. Automated testing, building, and deployment processes ensured high-quality code and fast feature releases.

Used Terraform to automate the provisioning of cloud infrastructure on Azure, including Azure Kubernetes Service

(AKS) for orchestrating the microservices. Infrastructure automation allowed for consistent and reproducible deployments across multiple environments.

Integrated SonarQube into the CI/CD pipeline to automate static code analysis, ensuring high-quality code and identifying vulnerabilities early in the development process as part of a DevSecOps workflow

Developed and deployed a real-time data sync feature using .NET 8's improved performance optimizations and enhanced async stream capabilities, ensuring seamless updates and reducing latency between the backend services and frontend user interfaces during high-traffic billing periods.

Used Azure Redis Cache to store frequently accessed data (e.g., recently viewed bills) and reduce the load on the PostgreSQL database, improving read performance.

Deployed the platform to AKS using Docker containers. The solution was set up for high availability with automatic scaling to handle peak traffic, especially around billing due dates.

Leveraged Azure Monitor and Application Insights to gain deep insights into the system’s health. Monitoring tools were used to track the performance of backend services, identify bottlenecks, and ensure quick issue resolution.

Utilized GitHub for version control and collaborative code reviews, ensuring smooth code integration and timely feature releases. Promoted best practices in CI/CD workflows, reducing deployment times and increasing release velocity.

Adopted Test-Driven Development (TDD) using xUnit and NUnit to ensure high-quality code coverage and integrated Selenium for automated UI testing within the CI pipeline, improving deployment reliability and reducing defects.

Mentored cross-functional teams on cloud-native architecture, microservices best practices, and DevOps automation, fostering seamless collaboration between backend, frontend, and operations teams across the municipal platform. Championed GitOps for insfrastructure management and InnerSource practices to enhance developer collaboration, code quality, and overall team productivity, leading to more efficient software delivery for the Finance Hub, Operations Hub, and Utility Billing System. Additionally, managed sprint planning, issue tracking, and project execution using Jira, ensuring streamlined workflows and timely feature delivery across all platform modules. Full Stack Developer
