Cybersecurity

Programming has been my hobby for almost 12 years now, and I've managed to gain a pretty good understanding of different programming techniques and principles. Writing APIs and backends has always been my favourite, but I can also make pretty good-looking frontend applications when needed.

Cybersecurity is also a significant interest of mine, and I've participated in many bug bounty programs and done penetration testing for almost five years. While co-operating with different companies' CERT and cybersecurity teams, I've gained a good understanding of incident response, vulnerability management and other cybersecurity processes.

I'm a Fullstack developer and a cybersecurity enthusiast from Helsinki, Finland. My focus area has always been backend development with TypeScript and Java because I enjoy creating the complex logic behind applications.

I've been interested in computers since I was a kid and have gained vast experience in many different topics. Usually, I did one of the following things: Played videogames or modded them, tinkered with computer hardware, learned new programming languages, worked on my homelab and self-hosted servers or tried to find exploits from bug bounties.

I also have the cutest dog in the world, and I love spending time with her. I also enjoy going hiking and camping in the summer.
