My Process

From Concept to App Store in 4 Steps

01

Concept

I understand the vision, target users, and requirements. Whether it's a new app or improving an existing one, I define what success looks like.

Discovery call + requirements doc
02

Design

Wireframes, prototypes, and HIG-compliant UI design. Every screen is planned for usability and visual appeal before a single line of code is written.

Figma prototypes + user flows
03

Develop

Native Swift and SwiftUI development with iterative builds. Using the latest frameworks.

TestFlight builds + weekly updates
04

Launch & Support

App Store submission, metadata optimization, and ongoing maintenance. I keep my apps updated and running smoothly after launch.

App Store submission + post-launch care
