Hi, I'm Liza

I keep infrastructure calm.

A DevOps engineer from Minsk. I build environments that pass audits, releases without manual magic, and backups that actually restore.

Cases

What the problem was, what I did and what came out of it. Work stories and my home lab — each one says which.

Work · MAISTREAM, payment services and e-commerce

A PCI DSS environment from scratch

The company's payment services needed a PCI DSS compliant environment. There wasn't one, so I built it from scratch and took it through the audits.

2 PCI DSS audits and 1 PCI 3DS audit — no critical findings

Releases: 30 minutes → 6

A Java application was built and deployed by hand. I moved it to CI/CD, and front-end apps and landing pages started deploying on push — with no engineer involved.

Release time from 30 to 6 minutes, no more manual build errors

Backing up the backups: a dashboard found 97%

I built a Grafana dashboard for my backups — and it immediately showed a problem that was invisible in the terminal.

Backup size 8.65 GiB → 427 MiB, storage 2% full instead of 97%

A Kubernetes lab as code

A cluster you can delete and bring back by following a runbook — together with its data.

A tested DR: terraform destroy → new cluster → restore from backup

I automated my own job search

A service that scores vacancies against my profile, tracks my application funnel and shows which skills are missing most often.

I can see where rejections happen and what to learn next — from data, not feelings
