Jeremy Gavrilov.
Just another guy who codes.

I'm a passionate and detail-oriented Full Stack Developer with a strong background in Java, Python, and Typescript. I love creating innovative solutions and leveraging technology to improve user experiences. Welcome to my personal website, where you can learn more about my skills, projects, and insights in the world of software development.

About Me

I have a B.S. in Computer Science from Syracuse University and about four years in the field between engineering at Amazon and contract work building apps and systems for small businesses. My goal is to help businesses leverage APIs, servers, and modern web & app stacks to make day to day activities easier and more efficient.

I thrive on tackling complex projects and am committed to staying current with cutting-edge technologies and industry best practices. When I'm not immersed in coding, you can find me adventuring through the urban jungle, unwinding with video games or a captivating movie, or expressing my creativity in the kitchen through baking.
