Güven ALTUNSOY

Software Engineer at Trendyol

İzmir, TURKEY

I focus on creating tools for an internal technology platform.

My interests are primarily in microservices and distributed systems, with a strong focus on reliability. I continuously build tools to strengthen both root cause analysis and reliability reviews. In addition, I actively enhance existing SRE tooling and develop new ones, empowering the team on both the offense and defense sides to increase overall system reliability and resilience.
