At BrightIT, I led a mobile team of three while contributing production code for iGaming apps, including core business logic for authentication and payments. I also maintained Kotlin and Swift integrations for customer support, identity verification, and geo-compliance.

I owned CI/CD pipelines that automated app builds, signing, and store submissions. I also standardized AI-assisted development workflows with custom Claude Code Skills, Hooks, and Subagents.

At Les Amis, I shipped Flutter applications for iOS, Android, and web, and redesigned onboarding and profile flows; the work improved user retention by 40%. I also helped deploy an AI-powered matching service on Google Cloud and built backend solutions with Node.js and FastAPI.
