Senior Frontend Developer

Trenutno zaposlen/a na neodređeno 1-2 godine


Jedna od najboljih kompanija za koju sam radio. Veoma snazna orijentisanost ka zaposlenima. Rade se projekti za sestre firme koji su inhouse. Lokacija je odlicna, postoji i parking, sto je retko na NBG. Work-life balans je odlican, nizak nivo stresa. Takodje je moguce napredovanje i sa Beogradske lokacije.
