Summary
🤩
Rockstar🎓
Top SchoolMargus Mahler is a senior engineering manager with 11 years of experience scaling developer-facing SaaS organizations and operational platforms from Estonia. He has led multiple teams at Twilio—growing backend ownership, delivering zero-downtime billing, and restructuring through a post-downsizing reorg—and now manages engineering at Sanity while running a small consultancy focused on PostgreSQL, GCP SRE, and architecture. Margus combines hands-on technical work (database and SRE expertise, migrations to Google Cloud, microservices adoption) with a track record of building and mentoring high-performing teams across product and infrastructure domains. He has repeatedly driven reliability and cost improvements at scale (e.g., Toggl migration to GCP, 99.97% uptime) and advised government and banking clients on platform architecture. Comfortable switching between strategic leadership and deep technical contribution, he often fills the gap between architecture, operations and hiring/candidate vetting.
