About Me

I am a Software Developer specializing in building scalable enterprise applications using Next.js and React. I specialize in developing robust backend services with .NET Core, optimizing database performance, and creating modern web applications.

I earned an Advanced Diploma in Computer Programming and Analysis from Seneca Polytechnic in Toronto, where I deepened my expertise in cloud infrastructure, databases, and DevOps practices. When I’m not coding, I enjoy exploring new technologies, working on innovative projects, and expanding my knowledge in cloud computing and container orchestration.
