I am a Team Leader and GCP Certified ACE with a Site Reliability (SRE) mindset. I specialize in building highly available, distributed backend systems that don't wake you up at 3 AM.
Currently operating high-availability e-commerce systems at Brack.Alltron, where I focus on robust Go/Java microservices, observability, and SLO-driven cloud architecture.
