🔴
play a key role in shaping the architecture of a big mobile ecosystem
Może oznaczać realny wpływ na architekturę, ale równie dobrze może być to standardowy opis roli, gdzie faktyczny wpływ jest ograniczony.
🔴
driving technical decisions
Może oznaczać faktyczne podejmowanie kluczowych decyzji technicznych, ale równie dobrze może to być fraza marketingowa, gdzie decyzje są podejmowane na wyższym szczeblu.
🔴
delivering high-quality solutions at scale
Wymaga to nie tylko umiejętności technicznych, ale także stabilnych procesów i narzędzi, które nie zawsze są gwarantowane.
🔴
Proven track record of building and maintaining large-scale mobile applications
Może oznaczać pracę nad prawdziwie dużymi i złożonymi systemami, ale równie dobrze może odnosić się do aplikacji z dużą liczbą użytkowników, ale prostą funkcjonalnością.
🔴
Agile deliver
Może oznaczać prawdziwie zwinne podejście do pracy, ale równie dobrze może być to tylko hasło, pod którym kryją się nierealistyczne terminy i presja.
