I am 19 years old student studying in high school interested in working part-time.
Being a software engineer with 3 years of experience in development of real-world applications for startups and businesses I am passionate about tackling challenging problems and delivering modern, scalable, and efficient software.
I am proficient at web technologies and have a wide background in the “traditional” development, however, when applicable, I leverage using low-code tools to facilitate workflow.
Primarily specialising in web applications, I enjoy learning new technologies and approaches as the tech landscape evolves.
