A Little About Me

I am a Full Stack Developer with 5+ years of experience building scalable, cloud-based web applications. I have a strong background in C#, modern JavaScript frameworks (React & Lit), and AWS. I specialize in developing enterprise-level platforms serving large user bases with a proven ability to collaborate across teams to deliver high-quality, maintainable solutions.

Currently at D2L, I build and maintain enterprise platforms used by millions, working across the full stack with C#, React, Lit, and AWS. I'm a Queen's University graduate with a specialization in Software Design and a constant drive to learn new technologies. I pride myself on strong problem solving, attention to detail, and writing clean, efficient code.
