André Medeiros
Director Of Software Engineering at TELUS
Ottawa, Ontario, Canada
Summary
🤩
RockstarAndré Medeiros is a Director of Software Engineering based in Ottawa with over a decade of experience modernizing backend systems, cloud infrastructure, and operational practices at scale. He led TELUS teams to deliver zero-downtime Black Friday operations, triple API performance via targeted caching and Redis migrations, and decommissioned legacy platforms to unlock multimillion-dollar savings. A hands-on engineering leader, André builds shared platform capabilities—auto-remediation, AI-assisted change validation, and dynamic templating—that accelerate delivery and improve release safety. His background includes leading distributed teams at Status and Shopify, shipping high-throughput logging and tracing systems, and contributing to core Ruby tooling like Bundler and RubyGems. He blends pragmatic reliability engineering with developer productivity improvements, and—unexpectedly for a director—still enjoys tinkering with retro computers, mechanical keyboards, and open-source build automation.
