About me:
Sole infrastructure owner of a staking/validator platform: 3 bare-metal Kubernetes clusters, 6 mainnet validators and public RPC nodes under 24/7 load

Wrote my own Go controllers for that platform: a readiness controller covering 30+ blockchain networks and a DNS controller that removed 100% of manual A-record work

Cut infrastructure costs by $1000/month with an inventory service, and saved ~$22,411/month at a previous company by rolling out AWS Control Tower

At VK Cloud built SLI/SLO monitoring for IAM and helped take it from 3K to 14K RPS after a production outage
