About Me

Hey there! I'm Toni Ruhanen, a Finnish full stack developer. I am currently studying Business Information Technology at Haaga-Helia University of Applied Sciences.

Programming has been my hobby for about 10 years and have a great understanding of different techniques and programming languages. I like backend programming more but I can also do frontend when needed. For the past four years, I have participated in many different CTFs and Bug Bounties, so I have pretty good understanding of cyber security.

I have been an administrator on one of the Finland's biggest gaming network with over 200 concurrent players. I have also managed many different servers both on cloud platforms and on dedicated machines.

If you have any questions, feel free to message me on
