Summary
👤
Senior🎓
Top SchoolJustin Vallely is a Principal Mobile Engineer with 11 years of experience, currently leading iOS architecture and app infrastructure at Ibotta from Colorado. He specializes in mobile payments, app reliability, and build systems—having built custom precompiled framework hierarchies and CI/CD tooling that dramatically sped incremental builds and releases. Justin blends hands-on engineering (Apple Pay, Stripe, Plaid, APM, feature-flagging) with cross-team influence on testing, security, and deployment strategy, making him a frequent decision-maker on company-wide technical tradeoffs. He also raises developer effectiveness through modularization, automation, and mentorship, and is comfortable moving between low-level controls engineering and high-level mobile product delivery. Outside software he applies the same systems mindset as owner and chief technologist of a Colorado micro-brewery that has earned regional awards, a detail that hints at his hands-on leadership and operational grit.
