David Blass is a full-time open source TypeScript developer and author of ArkType, a 1:1 validator for TypeScript. ArkType is the first validator to include a static parser that can infer TypeScript’s syntax as well as a full type system that can compare arbitrary pairs of types for assignability and automatically discriminate unions. Predictably, David loves parsers and types, but also bow ties and his wife’s vegan cooking. He lives with her and their 5 pets in Boston, Massachusetts, and is currently pursuing funding to continue working on ArkType full-time!

Among the different things that Facundo enjoys, some of them are meeting and connecting with other people, web development, and talking a lot.
