I am a software and backend engineer based in Oulu, Finland, working primarily with Python and Node.js.
My experience includes backend APIs, SaaS platforms, security software, research-data systems, infrastructure, and production-oriented applications. I focus on building systems that are maintainable, reliable, and practical to operate.
Alongside industry work, I am pursuing an M.Sc. in Software Engineering and Information Systems at the University of Oulu.
My research background includes federated learning, intrusion detection, cybersecurity, and distributed machine learning, with peer-reviewed work published in The Journal of Supercomputing.

Federated Learning · Intrusion Detection · Cybersecurity · TensorFlow · Flower
A federated-learning-based intrusion-detection project for distributed and security-sensitive environments.
I implemented and evaluated a lightweight 1D-CNN using Flower, including experiments under both IID and non-IID data distributions, with the goal of enabling distributed detection without centralizing sensitive client data.
