Duties and achievements:• Maintaining and refactoring a large legacy .NET application (deployed as an Azure AppService), a monolith ASP.NET Web API application based on .NET Framework 4.8. In particular, I am responsible for: ◦ Diagnosing and resolving performance bottlenecks through CPU profiling. ◦ Refactoring code to reduce coupling between distinct services, enhancing modularity. ◦ Increasing code cohesion by removing redundant code and optimizing class relationships, ◦ Fixing major bugs in server-side caching related to thread-safety and performance, ◦ Implementing comprehensive unit tests using nUnit for both existing and new code. • Designing and developing a new ASP.NET Core micro-service for notifications within the Catalyst Brief services. Some of its features include: ◦ Utilizing the FastEndpoints library to build an API on top of Minimal API endpoints, ◦ Implementing performance-critical services using gRPC. ◦ Leveraging EF Core for persistence on MS SQL Server, ◦ Adhering to Clean architecture principles for code organization, ◦ Integrating Azure Service Bus as the messaging platform for consuming events from Catalyst Brief services. • Documenting solution designs and specifications, ensuring clear communication within the development team, • Developing Proof of Concept features and engaging in discussions with tech leads and architects to validate proposed solutions, • Leading code reviews and approving pull requests from other developers, actively providing insights for improvement, • Contributing to architectural decisions in senior developers meetings, demonstrating a strategic mindset, • Sharing knowledge within the team and actively contributing to a collaborative and innovative work environment, • Making presentations on topics ranging from resilience strategies with Polly to functional programming techniques in C#

In my role as a Lead C# Developer, I led a significant project to enhance our operations team's efficiency by designing and implementing a new application. The application, built from scratch on .NET Framework 4.8 and DevExpress WinForms v21, aimed to achieve greater stability, concurrency, and responsiveness. Key contributions included: • Implemented the system architecture using the Command Query Responsibility Segregation (CQRS) approach, optimizing data processing and retrieval, • Developed a custom lightweight repository-level object mapper to streamline interactions with existing and new stored procedures in MS SQL Server 2016, • Engineered a caching mechanism coupled with incremental database queries, enabling close-to-real-time data visualization for improved user experience, • Successfully integrated the application with third-party systems, including Directum (a document management system), MS Outlook, and MS Excel, enhancing interoperability, • Optimized the usage of managed memory for .NET objects, ensuring efficient resource utilization and application performance, • Implemented advanced synchronization primitives to ensure thread-safe processing of user requests, contributing to a responsive and secure application.
