Tyler Macdonald
Director Of Engineering at REX
Guelph, Ontario, Canada
Summary
🤩
RockstarTyler Macdonald is a Director of Engineering based in Guelph, Ontario with nine years of experience scaling cloud-native platforms and leading cross-functional engineering teams. At REX he combined hands-on systems work with strategic vendor management—cutting AWS spend by over 60% while replacing brittle third‑party tools with cheaper, automatable alternatives and Terraform‑managed infrastructure. He standardized CI/CD for 180+ services, created per‑branch ephemeral QA environments to eliminate spreadsheet-driven processes, migrated the org to Postgres, and instituted incident management and end‑to‑end tracing. Less obvious: he personally wrote scrapers to extract vendor data for analytics and to hedge against vendor lock‑in, blending pragmatism with long-term operational resilience.
