Can Observability Reduce Your Tech Debt? | Live Laugh Logs Ep. 5 with Wilco Burggraaf

Oct 28, 2026

Your telemetry data can reduce engineering complexity AND make your software more sustainable - find out how in this episode!

Welcome to Episode 5 of Live Laugh Logs, the podcast from the Coralogix Developer Relations team. This week, Annie is joined by Wilco Burggraaf, Principal Lead at HighTech Innovators and host of the Sustainable IT Action Netherlands meetup.

We go looking for waste using data you already have, and discuss the hidden inefficiency in data platforms like Databricks and Spark, whether using AI to query your systems is actually more efficient than doing it yourself, and how to measure AI's own energy footprint. Plus, how Wilco's team at HighTech Innovators ended up recommending Coralogix to their own clients, why flame graphs are one of the most underrated tools for finding code-level waste, and how Annie uses the Coralogix CLI through Claude Code to find under-utilized infrastructure in minutes.
