CI/CD & app release
Shipping is part of engineering. I work in branch-based GitHub workflows, use automated unit/integration/E2E and static checks where appropriate, deploy web and FastAPI services to managed cloud environments such as Vercel, and use Expo/EAS for mobile build, signing, submission, testing, and update workflows. I am comfortable with the operational work required to move an app through both Apple and Google release systems repeatedly.
