What I'm looking for

I'm looking to build reliable cloud-native platforms, improve automation and observability, and advance AI-enhanced SRE workflows for high-availability systems.

At HelloBetter, I manage end-to-end reliability for a Berlin-based platform, tuning Kubernetes deployments and scaling GPU-accelerated AI/ML workloads on Amazon EKS and RunPod.

I've built GPU observability with Prometheus, Grafana, and NVIDIA DCGM, integrated Claude, GPT, and Gemini into SRE workflows, and reduced MTTR by 40%. My resource right-sizing and spot-instance strategy reduced cloud overhead by 30%.

Across Nexible, Valassis, Delivion, SecureKloud Technologies, and Marvel Softech India, I've delivered CI/CD, cloud migrations, infrastructure as code, containerization, monitoring, and Linux operations. I bring 15+ years of experience supporting high-availability infrastructure across healthcare, insurance, and IT.
