Ihar Varauka Perfinium — Scale with Confidence
// SRE & PLATFORM ENGINEER

I keep infrastructure fast, reliable and cost-efficient.

Reliability engineering for teams running on AWS, GCP and Kubernetes. I design production systems, cut cloud spend, and build the observability and automation that let engineers ship without fear.

// 01 — HOW I CAN HELP

Platform engineering, end to end.

01

Cloud & Kubernetes platforms

Architect, build and operate production-grade Kubernetes on AWS & GCP — from cluster design to self-service tooling for your engineers.

02

FinOps & cost optimization

Cut cloud bills without cutting reliability. Usage visibility, right-sizing and architectural changes — the kind that took ~70% off a real bill.

03

Observability & SLOs

Prometheus, Thanos, Grafana and CloudWatch platforms with meaningful SLIs/SLOs — so you find problems before your users do.

04

IaC, CI/CD & GitOps

Terraform, AWS CDK, GitLab CI and GitHub Actions. Repeatable provisioning and delivery pipelines your team can actually own.

05

Reliability & scaling

High-availability design, autoscaling GPU/AI workloads, Kafka data pipelines and migrations that improve DR and scale.

06

Security & compliance

Harden infrastructure for standards like ISO 27001 — reducing risk while keeping delivery moving.
