Résumé/Web: https://valiukas.dev/resume-linas-valiukas.pdf Email: linas@valiukas.dev I am a Lead/Staff Backend Engineer with 15+ years of experience. I specialize in reducing cloud costs, scaling large databases, and debugging systems at the syscall level. Highlights: * Saved $500k/year at Automattic: reduced S3 storage costs by 75% for a 2 PB dataset. * 26x Performance Increase: Architected a bespoke binary protocol for WordPress restores, eliminating the #1 product churn reason. * Scale: Managed a 30 TB+ PostgreSQL cluster (Citus) and NLP pipelines for MIT/Harvard for 10 years. * Recent Build: Solo-founded https://aero.zip - a privacy-first file transfer service with E2E encryption and OPAQUE authentication. I debug GnuPG with strace, migrate petabytes without downtime, and replace brittle Cron jobs with robust workflow systems. Looking for complex backend challenges. |
