At Steniant Oy, I designed and implemented a web-based booking and cashing system to track event participants, fees, and team balances. I handled the development workflow independently, from setting up the environment to deploying and testing features.
At SecLab-Centria, I developed intentionally vulnerable web applications for teaching students common security flaws, including SQL injection. I implemented secure and insecure database interaction variants using PHP/SQL and Node.js/SQL, and prepared the applications for reuse in future courses and lab exercises.
At Centria-University of Applied Sciences, I developed a web application to digitise trainee paperwork and reduce repeated form filling. I designed reusable form fields and implemented data storage and retrieval with PHP, SQLite, and a JavaScript frontend.
