- Lead DevOps & Infrastructure @ BlancVPNEstonia - RemoteSummary:
- Building and operating the infrastructure behind a commercial VPN service distributed across 50+ locations. Work centres on keeping the internet open where it is filtered: censorship-resistant access, exit node quality and the observability needed to prove both.

- Took hand-edited DNS records off the critical path of bringing a location online, with atomic applies and an auditable change history
