I am a .NET full-stack/back-end developer who worked as part of the .NET Core development team responsible for a centralized service for retrieving information about available public transportation benefits.

I configured and migrated the messaging infrastructure from RabbitMQ to Kafka, and I implemented a Redis-based caching system that improved request performance by 2–5x. I also increased unit test coverage for a key component from approximately 10% to 78%, covering around 2,800 lines of code.

I designed and implemented an efficient document upload solution for the service's file storage system. I onboarded and mentored two new team members, initiated the adoption of bUnit for Blazor component testing, and collaborated closely with QA engineers and business analysts throughout the development lifecycle.

I take ownership of quality by investigating and resolving reported bugs and production issues, and I enjoy working with modern infrastructure and clear APIs. My approach is to deliver practical improvements—performance, reliability, and maintainability—without losing developer experience.
