Eyal Blum is a seasoned software engineer with over 15 years of experience building reliable mobile platforms and developer tooling, currently shaping product at Figma after leading Android RCS onboarding at Google to upgrade SMS for over a billion users. With dual training in computer science and mathematics, he has repeatedly driven architectural decisions as a staff engineer at Dropbox and Meta, deciding which stacks to adopt or retire and authoring core mobile libraries used at scale. He contributes to Kotlin Multiplatform open source—improving Store’s error handling, fetcher behavior, and memory safety—demonstrating a pragmatic focus on robustness and testability. Eyal blends deep platform expertise (Kotlin, Swift, Android, databases) with a history of improving performance and reliability as services scale from millions to billions of users. He’s based in San Francisco and brings a rare combination of hands-on implementation skills and strategic technical leadership across startups and large tech companies. Notably, he favors practical engineering trade-offs—sometimes choosing to “write twice” in native languages to improve long-term maintainability.
