I'm currently getting started as a Game Tester and have a strong interest in indie game development. While I haven't worked on a professional title yet, I’m learning game development with Godot and working on two of my own projects: Jonah: The Redemption Path, a narrative-driven 2D platformer, and a mobile duel game. I have experience in design and visual tools like Photoshop, and with a background in architecture, I’m used to analyzing visual and interactive design from a user-focused perspective. I'm fluent in English and have years of gaming experience, which helps me identify gameplay, balance, and usability issues. I’m actively improving my QA testing and bug reporting skills, and I’m flexible with pricing.
