About me

I am a versatile software developer with strong full-stack expertise, covering front-end, back-end, and application architecture. I work confidently across the entire development lifecycle — from designing user interfaces and APIs to building scalable back-end systems and data-driven solutions. Based in Turku, Finland, I focus on delivering robust, maintainable, and performance-oriented software.

My technical background includes front-end development with HTML, CSS, JavaScript and React-style architectures, back-end development using Python, JavaScript, and C#, as well as working with relational databases such as MySQL. I have hands-on experience designing APIs, structuring databases, and implementing clean software architectures that support scalability, security, and long-term maintainability.

I have built and maintained real-world applications involving API integrations, automation systems, data collection and processing pipelines, and AI-powered features. My experience spans both independent projects and team-based development, where I contribute not only code but also architectural decisions, optimization strategies, and a strong focus on user experience and system reliability.
