What I'm looking for

I am looking for a role that fosters innovation, collaboration, and continuous learning, where I can leverage my skills in software architecture and development.

As a Senior Software Engineer with extensive experience in designing and developing scalable RESTful APIs, I have a proven track record of implementing microservices architecture and enhancing system performance. Currently, I lead the development of asynchronous processing pipelines at SmartCode, utilizing .NET 8 and C#. My commitment to clean code and best practices in CI/CD ensures rapid and safe deployments.

Previously, I worked with Staples in Canada, where I led the design of microservice-based architecture, significantly improving service resiliency and reducing post-release bugs by 40%. My experience spans across various roles, including Full Stack .NET Developer in Ireland, where I modernized legacy applications and mentored junior developers. I thrive in collaborative environments, bridging the gap between technical teams and stakeholders to deliver high-quality solutions.
