About

Ship first. Theory second.

I learn by shipping real products - Play Store apps, TV players, and automation on a VPS.

I'm Vasyl Raiskyi - a freelance Android developer from Ukraine. I design, build, and publish apps for mobile and Android TV under Tiar Apps.

Focus: local networking, file sharing, media tools, and developer utilities. I own the full path - architecture, implementation, release, and support.

Right now I'm deepening Python toward Odoo development (ORM, XML views, PostgreSQL, Docker) - while staying open to Android roles.

path → Android products · learning → Python / Odoo · open to → remote
