I'm a full-stack software developer with over six years of experience building scalable, high-availability applications in .NET, Python, and JavaScript. My work spans backend development, API design, cloud computing, and automation, with a strong focus on data processing and system optimization.

I have experience working with financial systems, fleet management solutions, and enterprise applications, contributing to both backend and frontend development. I specialize in C#, .NET Core, React, SQL, PostgreSQL, and cloud platforms like GCP. My expertise includes designing efficient databases, implementing automated testing with xUnit and Selenium, and integrating identity management solutions like Keycloak.

I'm a Software Developer Intern at Geotab, where I work on enhancing .NET applications, developing automated testing frameworks, and analyzing large-scale telematics data. Previously, I worked at BRAC IT, leading the development of meeting management and banking applications, optimizing workflows, and building predictive analytics modules.

I enjoy solving complex engineering problems, improving system performance, and working with data-driven applications.
