Our team embarked on a multi-year initiative to deconstruct a monolithic application into a loosely coupled, event-driven microservices architecture. We adopted a choreography approach for inter-service communication, aiming to enhance flexibility and scalability. The primary challenge was meticulously decomposing the existing monolith to prevent any operational disruptions in the market during the transition.

We developed a three-year roadmap with the ambitious goal of completely retiring the monolithic system. By the end of my tenure, we had successfully completed approximately 50% of this roadmap. Furthermore, all critical architectural decisions were finalized, and comprehensive code conventions and design patterns were established to guide future development and ensure consistency across the new microservices landscape. This foundational work significantly de-risked the remaining migration effort and set a clear path for the complete modernization of the system.

I developed a service-oriented system in .NET Core 3.1, designed to deliver comprehensive withdrawal and deposit functionalities to end-users. The system's core architecture was robust, featuring a rule engine for processing complex business logic, dedicated authorization and payment services to secure and manage transactions, and a suite of background jobs. These jobs were crucial for monitoring uncompleted transactions, ensuring they were correctly processed and moved to their appropriate final state, thereby maintaining data integrity and user trust.

I contributed to a German eCommerce platform that enabled users to purchase modern hearing aid devices. Within this multi-team project, I developed critical integration points to acquire and populate our database with essential data. I was also actively involved in architectural discussions, particularly focusing on decreasing coupling between teams and optimizing workflow strategies to enhance overall system efficiency and scalability.

I contributed to a .NET-based application crucial for hospitals to track and monitor the sterilization of medical instruments like surgical scissors. This software featured a rich UI and a multi-project back-end solution. My involvement began during the system's complete rewrite from Delphi to the .NET stack, modernizing its capabilities and underlying technology.
