TECHNICAL ARTISTRY

Technical Skills

A focused view of the architecture, networking, realtime systems, and production practices I use to ship reliable mobile apps.

MOBILE ENGINEERING CORE

Mobile apps are not just screens.

A production-grade product needs architecture, networking, realtime communication, analytics, release stability, and maintainable team workflows.
