Senior🎓
Top SchoolLuiz Kowalski is a Senior Software Engineer based in Berlin with 13 years of professional experience and over eight focused on Ruby and Rails. He has driven API and performance-focused work across companies like Contentful, Shopify, and Finiata, and has hands-on experience migrating cloud providers and balancing NoSQL and SQL solutions. Luiz prefers domain-driven design and monolith-friendly architectures over microservices, and recently concentrated on multithreading, concurrency, and low-latency services. He’s comfortable leading teams, doing PR reviews and pair programming, and has a history of extracting resilient services from monoliths (payments, auth) to improve availability under load. A curious technologist and frequent experimenter, he also builds side projects like useswitchboard.app and keeps an active GitHub presence where he invites collaboration.
