About

I am a full-stack developer with experience in modern web applications and cross-platform mobile development.

I am currently completing Full-Stack Developer Training through Opiframe, including work-based training at Coubonga Oy. My current work focuses on full-stack development with Angular, ASP.NET Core, C#, Entity Framework Core, SQL databases, and REST APIs.

At BeyondOS, I worked 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 full-stack web development using TypeScript, React, Angular, Node.js, and .NET, supported by experience with relational databases and cloud deployments.
