Building cross-platform apps and reliable web systems.

Aki-Petteri Kuivas · Full-stack Developer

Web-focused full-stack developer (Next.js, React) in Oulu, Finland. Open to web and mobile roles.

About

I am a web-focused full-stack developer specializing in modern React and Next.js applications, with experience in cross-platform mobile development.

Most recently, I worked at BeyondOS across multiple company projects, collaborating closely with the CMS team on a gaming content management system. My work focused on improving user experience, content workflows, and reliability while working with a distributed development team.

At Monidor Oy, I built cross-platform prototypes for iOS and Android using React Native and Expo, including configuration and remote monitoring applications based on existing Java systems. My bachelor's thesis focused on push notifications in a cross-platform application, covering a prototype routing server and Android/iOS apps.

My background includes electrical and automation engineering studies and over ten years in the construction product industry, before transitioning into software development in 2021. I graduated from Oulu University of Applied Sciences (OAMK) with a Bachelor of Engineering in Information Technology in 03/2025 while working in software development roles.

My current focus is web application development with Next.js and React, complemented by backend experience with Node.js, SQL databases, and cloud-based deployments.
