Summary

Rockstar🎓
Top SchoolKrzysztof Zabłocki is a Principal Swift engineer and consultant with 11+ years building production iOS apps and developer workflows for companies from startups to The New York Times and The Browser Company. He combines hands-on engineering (shipping apps like Headspace and NYT) with developer-tooling expertise—his open-source Sourcery meta-programming tool and other libraries power over 80,000 apps. As a consultant he audits codebases, designs pragmatic, maintainable architectures, and creates automation that has saved clients millions in engineering costs. He’s led teams of 20+, created internal developer platforms and onboarding, and frequently speaks at conferences worldwide about practical iOS architecture. Unusually for an app-focused engineer, he blends UX sensibility with deep build-system and codegen knowledge to improve both product and developer experience. Based in Warsaw, he also co-founded Pixle, whose apps earned multiple Apple features and awards.
