Summary
Sebastian Glazebrook is a seasoned engineering leader and founder with 14 years of experience building and scaling high-throughput, distributed financial systems and consumer platforms. He combines deep hands-on expertise in Ruby on Rails, Postgres, AWS and database sharding with a proven track record of growing teams and operational practices—most recently founding 13th while leading engineering at AWS and previously building Cash App’s Issuing org from a single engineer to a global team of 40+. Sebastian is pragmatic about quality: BDD/TDD, RSpec and clean, tested code are non-negotiable, and he has driven SRE and reliability best practices across large organizations. He’s delivered measurable business impact (e.g., enabling Cash Card to support millions of cards and billions in transactions) and repeatedly modernized architecture and delivery workflows at companies like Redbubble and REA. Equally comfortable mentoring leaders or shipping low-level infrastructure, he brings entrepreneurial curiosity informed by prior freelance product building and a background spanning sound engineering to network certifications.
