What I'm looking for

I want to build and own features end-to-end—UI through backend to deployment—working async with clear documentation. I’m looking for remote opportunities where I can maintain and grow real paid products using React/Node and React Native.

I’m a self-taught developer with 7 years of hands-on experience building production software, specializing in the MERN stack and React Native. I designed, built, and independently operate Naneport, a live multi-tenant SaaS platform with subscription billing and a self-service admin panel—comfortable owning features end-to-end from UI implementation to backend and deployment.

My work focuses on delivering async, well-documented output and maintaining the product in production, including recurring payments, grace-period logic, staged access restriction, and data retention/deletion policies. I also built related products like KristalENGINE (a custom game engine + compiler) and Konolith (an in-browser AI-assisted 2D/3D game IDE), and I’m fluent in English and Turkish.
