I built production Android applications with Java, Kotlin, and Firebase as a self-employed software engineer and Android developer. I migrated a legacy codebase to Clean MVVM Architecture and developed an AI-powered fraud detection system using Python and scikit-learn, exposed to an Android client through a REST API.
As a self-employed UI/UX designer, I delivered end-to-end design for mobile and web applications, from user research through production handoff in Figma. I’ve also built a real-time messaging app, an idempotent payment API, and responsive web interfaces.
