Rockstar🎓
Top SchoolPaulo Koch is a seasoned technology leader and current CTO with 17 years of experience building and operating large-scale web and distributed systems from Porto, Portugal. He combines hands-on backend expertise (Ruby/Rails, Python/Django, SQL, Kafka) with strong security and ops instincts—provisioning infrastructure with Terraform, automating CI/CD, and embedding security early in the lifecycle. As a founder and senior executive he has transformed engineering workflows at startups and scale-ups, introducing measurable practices around visibility, incident response, and predictable delivery. He has practical experience designing data-centric microservice architectures, GDPR/HIPAA compliance, and cryptographic cold storage for crypto assets. An active contributor to open-source (notably improvements to the fastavro Python library), he still runs short, frequent technical check-ups and rapid feedback loops to keep teams aligned. Colleagues know him for pragmatic process design that balances boundaries with developer autonomy and for stepping into gritty incident calls when things are on fire.
