About

Szilárd Attila, Nagy
Senior DevSecOps Engineer

As a Computer Science Engineer, I have acquired a diverse range of knowledge in computer networks and programming languages. My experience includes collaborating with the Networking Research Team at Budapest University of Technology, where I honed my problem-solving skills, working both independently and in a team tackling novel challenges. Throughout my Master’s studies, I expanded my expertise in service delivery, encompassing both traditional and cloud-based networks.

My professional journey started at a London-based startup, where I was entrusted with full ownership and responsibility for multiple projects, which allowed me to gain valuable experience and expertise. Building on this foundation, I have since expanded my skillset as a Software Architect and as a Lead Developer in Sweden.

I am currently seeking new and exciting challenges to further my career.
