I'm a full-stack engineer with 4+ years of experience, specializing in backend systems and scalable architectures. Based in 🇫🇮 Turku, Finland, I build end-to-end applications using React, Next.js on the frontend, React Native for mobile, and FastAPI, Django, Node.js on the backend, with strong expertise in database design, API architecture, and cloud infrastructure.
While proficient across the full stack, my strongest expertise lies in backend development—designing RESTful APIs, implementing microservices, optimizing database queries, and architecting systems that scale. I've built production systems handling millions of requests with modern frontend experiences and cross-platform mobile applications to match.
When I'm not coding, I'm exploring new technologies, contributing to open-source projects, or learning Finnish (currently in progress!). I believe in continuous learning and staying updated with industry trends.
