Summary
🤩
Rockstar🎓
Top SchoolAkiva Leffert is a Staff Engineer with 14 years of hands-on and leadership experience building mobile and web systems, currently focused at Hillspire after senior engineering and product leadership roles including VP of Engineering at Cortico. He combines deep iOS expertise—contributing important refinements to the widely used SnapKit autolayout library and to the Open edX iOS app—with experience running engineering teams at scale in high-pressure, mission-driven environments like political campaigns and fintech. Comfortable shifting between individual contribution and people leadership, he has shipped platform-level refactors, stabilized large codebases, and improved developer ergonomics (for example introducing FloatConvertible and source-location debugging into SnapKit). A Carnegie Mellon CS graduate, he’s as likely to write a clean protocol hierarchy as to drive hiring, architecture decisions, or cross-functional product work. Notably, his GitHub bio’s wry line hints at a pragmatic, slightly irreverent approach to engineering and collaboration.

A Swift Autolayout DSL for iOS & OS X
Role in this project:Mobile Developer (iOS)
Mobile Developer (iOS)Contributions:6 commits, 3 PRs, 17 comments in 1 day
Contributions summary:Akiva focused on improving the SnapKit library, a Swift Autolayout DSL. Their contributions centered around refining the core functionality and API of the library. This included introducing a `FloatConvertible` protocol to simplify constraint definitions, refactoring code to use `SourceLocation` consistently for debugging, and restructuring the protocol hierarchy for easier maintenance and future enhancements. The user also exposed `snp_location` for access to the source file and line number where the constraint was made.
