Javascript Developer & Node.js Developer

Der Kandidat ist ein Node.js/Typescript-Entwickler mit einem halben Jahr Erfahrung. Er hat jedoch fast 15 Jahre Erfahrung in C++, wo er Maschinensteuerungen für die Rasterbildverarbeitung programmiert hat. Letztes Jahr begann er, C#, GraphQL und Golang zu lernen. Im Februar begann er mit der Arbeit an einem Projekt in Node und Typescript. Für Datenbanken arbeitete er mit MongoDB, das in der Cloud lief. Er hat in der Vergangenheit auch mit SQL gearbeitet und hat nun begonnen, es zu Hause wieder zu lernen. Bei dem Projekt, an dem er gearbeitet hat, lief Node auf Kubernetes und wurde in Docker bereitgestellt, so dass er weiß, wie diese Technologien funktionieren. Er hat auch schon mit Rust, Git und Github gearbeitet. Er weiß, wie Scrum funktioniert, hat aber noch keine praktische Erfahrung damit. Die englische Sprache ist für ihn ein Problem, da er seit 10 Jahren nicht mehr in dieser Sprache kommuniziert hat. Die schriftliche Kommunikation und das Verstehen von gesprochenem Text bereiten ihm jedoch keine Schwierigkeiten. Er arbeitet gerne am Back-End und an Cloud-Technologien.
