Guide the Mendix native mobile build (iOS and Android), including offline drafts, secure storage, biometric login, push notifications and in-app payments.

Work with the DevOps Engineer on CI/CD for Mendix web and native mobile builds, environment promotion and releases in waves.
-
Set development standards, run code reviews, estimate work and track progress through each wave and tollgate.

-
Mentor developers onsite and offsite, and hand over documentation to the client's support team.
