My name is Jazz and I enjoy planning and building software using various technologies such as JavaScript, Java, and PHP. I am more focused and hands-on on the backend side of tech, but also occasionally enjoy the creative aspect of frontend development. My main experience is in developing web applications and APIs using several frameworks, such as ExpressJS and NestJS as well as databases like PostgreSQL and MongoDB. I am currently learning how to design and build scalable system architectures and data-intensive applications. I am also exploring other frameworks and tools to expand my skill set.
