## Resume and code resume

I help startups ship reliable systems, cut cloud waste, and automate operations.

**Role:** Senior Backend & DevOps Engineer
**Focus:** Backend Reliability & Architecture, CI/CD & Deployment Pipelines, Cloud Cost Optimization, AI Automation & DevOps
**Core stack:** Kubernetes, Docker, Terraform, PostgreSQL, Redis, Kafka, AWS, GCP, Hetzner, React, Node.js

Impact:
- 60-75%: Cloud cost reductions on migration and optimization projects
- 50K+: Daily users supported by systems I designed and shipped
- 99.9%: Availability and delivery performance in production systems

Principles:
- Prefer simple architecture over fashionable architecture.
- Measure before optimizing and optimize only proven bottlenecks.
