She focuses on system quality, chaos engineering, and observability. After starting her career in testing, she quickly learned that shipping reliable software takes more than just technical skill. She now coaches multiple e-commerce teams while untangling the human side of software delivery. She explores why perfect technical setups—like automated canary deployments—often stumble when they collide with organizational culture. She is a regular speaker at software conferences like HUSTEF, Agile Testing Days, and AutomationSTAR. ## Past Sessions ### World Congress 2026 Europe · July 8, 2026 Berlin, Germany - [When human meets canary](https://www.wearedevelopers.com/videos/100233-when-human-meets-canary) · 30 min · 🎥 Watch recording ## Videos - [When human meets canary](https://www.wearedevelopers.com/videos/100233-when-human-meets-canary) · Sonja Nesic ## Links - [LinkedIn](https://www.linkedin.com/in/sonja-n-23595638)
