What I'm looking for

I am looking for a role that allows me to leverage my backend development skills while fostering collaboration and innovation within a dynamic team.

As a Senior Full Stack Developer, I have a strong focus on backend development using C# and .NET. My experience includes designing scalable APIs and data-driven systems for high-traffic platforms. I have a proven ability to improve system performance and automate workflows, which has led to significant efficiency gains in my projects.

At AstroSirens, I led the development of a driver feedback and scoring API, integrating various data sources to enhance user experience. I also created a job allocation scheduler that reduced manual assignment by over 70%. My work emphasizes collaboration and mentorship, as I enjoy supporting junior developers and fostering a productive team environment.
