Outsourcing software engineering or hiring freelance app developers is one of the most critical decisions an executive or startup founder can make. Choosing an inexperienced developer can lead to bloated code, security vulnerabilities, and missed market deadlines. In this playbook, we outline the exact vetting criteria used by tech leaders to hire top-tier development talent.

1. Evaluate Live Production Apps, Not Static Portfolios

Figma mockups and static screenshots can hide poor engineering. Always demand links to active production applications live on the App Store or Google Play. Test the apps for frame drops, offline error handling, and battery consumption.

2. Require Code Quality Audits & Architecture Reviews

Ask prospective engineering teams about their architectural principles: How do they enforce state management? What is their strategy for API security, token refresh cycles, and database indexing?
