Who am I?
Teemu Rajaniemi
I'm a generalist: I do a bit of everything, from design and code to testing and launch. My background is in business information technology, web development and game programming.
In my free time I make browser games with AI. I design the games and their worlds, direct the implementation, playtest them with friends and fix them based on feedback. I publish them myself on Cloudflare and collect them on my Game Puppeteer site.
My goal is to keep growing and to build projects I can be proud of.
