Programming has been my hobby for over 13 years now, and I've managed to gain a pretty good understanding of different programming techniques and principles. Another interest of mine is Information Security, and despite my young age, I've already gained a lot of experience in the field, both in the offensive and defensive side. My specialities include incident response, penetration testing, and malware development.
I'm a Fullstack developer and a cybersecurity enthusiast from Espoo, 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.
During my free time, I enjoy hiking, camping in the summer, and playing with my dogs. I'm also a volunteer firefighter.

What can I do?
- Information Security
Information Security has been a hobby of mine for a long time now. Even though I'm still relatively young, I've already gained a lot of experience in the field. I have seen both sides of the coin, as I've done both offensive and defensive work.
I have a lot of experience in Incident Response, and it's one of my favorite things to do. I enjoy going thru logs and finding out what happened, and piecing everything together. Some of my other favorites things in the field are Threat Hunting and Penetration Testing. I also have good communication skills, and I like cooperation between different stakeholders.
During my so far pretty short but eventful career, I've also had the opportunity to work with many different SOC operators, internal security teams, as well as some government agencies like Traficom (CERT-FI). In 2019 I was interviewed by Traficom for their website about my experiences as a white hat hacker.
