## What I'm looking for

```text
I’m looking for a remote DevOps, SRE, or Platform role.
```

## About

```text
At Sber, I traced backend crashes to a CPU limit that caused Redis timeouts and liveness-probe failures, then fixed the deployment through GitOps and ArgoCD. I also built a distroless Node 24 image, reducing its size from 223 MB to 94.5 MB.

At Special Control Technologies, I designed and implemented Vault and External Secrets Operator delivery for Kubernetes, replacing manual password hand-offs with secrets pulled directly from Vault and rotated. I’m looking for a remote DevOps, SRE, or Platform role.
