what i value.

// what makes a role worth getting excited about

$ what_i_value

> impact — products used by real people at scale, that meaningfully improve their daily lives — I care deeply about what I build
> challenge — complex algorithms, distributed systems, performance-critical code — technically hard problems are what keep me engaged
> ownership — end-to-end responsibility over features and systems, from design to production
