Android developer behind Scanfold, an offline PDF scanner published on Google Play, and Shoply, tested with 340+ automated tests.

I took Scanfold from idea to Google Play release as a solo developer. It scans, organizes, searches, and exports documents offline, using on-device ML Kit for text recognition.

I also built Shoply, an e-commerce Android app with browsing, checkout, and order tracking. I covered it with 340+ automated tests and enforced architecture rules with Konsist.

As an independent Android developer, I own project specifications, UI, architecture, testing, and release. In my current freelance work as an AI Model Evaluator, Coding at DataAnnotation, I write and review code for AI training tasks and assess model-generated solutions.
