Building Bulletproof Systems: Warren Parad on Software Engineering for High Availability

SummaryIn this episode of the Overcommitted Podcast, hosts Bethany and Erika sit down with Warren Parad, CTO and co-founder of Authress, a user authorization API built for reliability. Warren shares how his team stayed fully operational during the massive AWS US-East-1 outage in October 2025 using DNS failover and multi-region strategies, and what the delayed alert logs taught them about timestamp trust. The conversation kicks off with a candid discussion on AI agents and critical thinking, whether managing multiple coding agents is really multitasking or just micromanagement, and what the trade-offs mean for early-career engineers. Warren traces his reliability-first mindset back to his roots in electrical engineering and healthcare IT, where late-night on-call pages through Citrix proxies and hospital billing systems shaped how he thinks about uptime today. The group also explores what it really takes to build a Five Nines organization and how hiring practices need to match the reliability culture you want. The episode wraps up with a round of Never Have I Ever: SRE Edition, featuring Friday deploys gone wrong, blaming DNS, and discovering outages from customer tweets.LinksAuthress, Warren's company, user authorization API for software makers.
