Hi there! I’m a Security Test Engineer with a passion for making software more secure and reliable. Right now, I'm part of a security team at Nokia, where we automate our security testing to ensure smooth, secure releases for Nokia products. My journey into tech has taken me from freelancing to a research stint in Tokyo, where I dove into scalability and similarity search on supercomputers. With experience across software testing, front-end, and back-end development, I’m all about learning, adapting, and solving problems to create safer, smarter tech solutions.

Experience

Security Test Engineer

Nokia | Finland, Helsinki

I joined Nokia as part of a team focused on automating security tests through our CI pipeline. Together, we work to make sure every Nokia software platform release is as secure as it is efficient, providing a solid foundation for client applications and services. My work helped shift our security testing from a manual process to a automated system—making releases smoother and safer.

Visiting Researcher

The University of Tokyo | Japan, Tokyo

As part of an exciting research exchange program between Aalto University and UTokyo, I explored similarity search libraries and tested their scalability on supercomputers. This experience allowed me to work closely with researchers in Tokyo, diving into some truly cutting-edge tech in the process.

September 2019 - December 2019

Freelance Developer

Self-employed | Freelance

My freelancing journey started with front-end web development, and before long, I expanded into the back-end, developing into a full-stack developer. Each project challenged me to learn new tools and frameworks, ultimately giving me a well-rounded skill set in web and software development.

September 2016 - June 2019

IT Testing Specialist

ZUNO by Raiffeisen Group | Slovakia, Bratislava

At Zuno, I was part of a team focused on testing and maintaining banking system applications. I analyzed logs, reported bugs, and ensured smooth functionality, later moving on to oversee testing for credit card products. This role gave me hands-on experience with critical banking systems, and I even had the chance to apply my knowledge to my thesis on encryption key security during an HSM installation.
