April 21, 2026 — In my role as VP of Engineering, I bring years of hands on experience applying observability techniques. I started in highly sensitive environments like FinTech, and now use the same practices in the WordPress ecosystem, supporting high traffic websites where uptime and performance directly impact business outcomes. This experience has helped me identify reliable tools and practical tactics that deliver strong results with minimal effort, offering an excellent benefit to effort ratio. From Reactive to Proactive: Modern Observability for WordPress

November 2, 2025 — ‘It works on my machine’, ‘We can’t test that in staging’, ‘It seems to have been broken for a while’… This sounds familiar to many of us, and this is what I want to fix with this talk! I will share practical & easy ways to approach observability in WordPress, and move beyond logs to investigate and fix issues on websites, plugins & themes. I’ll demonstrate how modern observability turns reactive firefighting into proactive problem-solving, drawing from our experience maintaining some of WordPress’s most popular plugins.

June 7, 2025 — It works on my machine’, ‘We can’t test that in staging’, ‘It seems to have been broken for a while’… This sounds familiar to many of us, and this is what I want to fix with this talk! I will share practical ways to approach observability in WordPress, and move beyond logs to investigate and fix issues on websites, plugins & themes. I’ll demonstrate how modern observability turns reactive firefighting into proactive problem-solving, drawing from our experience maintaining some of WordPress’s most popular plugins. The audience will discover:

– How to implement error monitoring platforms like Sentry to catch issues before users do (thanks to an open-source & free WordPress plugin!)
– Using Metabase for data-driven insights to proactively observe and understand issues (open-source & free!)
– Visual regression testing with BackstopJS to prevent UI breaks (open-source and free!)
– Real-world examples of how these tools helped our teams manage daily deployments effectively

Whether you’re a plugin/theme developer or managing WordPress sites at scale, you’ll learn practical approaches to spend more time building features instead of fixing bugs. Audiences from website/business owners (even not technical), to developers & agencies can join!
