PORTFOLIO nima va u qanchalik muhim?

Portfolio — so‘zi ingliz tilidan tarjima qilinganda “muhim hujjatlar papkasi” degan ma’nonini bildiradi. Shuningdek, portfolio mutaxassisning o‘ziga xos yutuqlari jamlanmasi vazifasini ham bajaradi

Portfolio – frilanserning bajargan ishlaridan iborat toʻplam.

Frilanser uchun eng ustuvor narsa bu uning portfoliosi hisoblandi. Agar portfolio boʻlmasa buyurtma olish deyarli nol foizga teng.

Oʻzingiz uchun kuchli portfolio yarating. Unda qancha ish boʻlgani muhim emas muhimi ular kuchli bo’lishi kerak va sizning mahoratingizning to’liqligicha namoyish etilishi zarur.

Siz hoh fotosuratchi, dasturchi, dizayner bo’lsangiz ham, mustaqil portfoliosiz ish topishingiz juda qiyin boʻladi. Agar siz o’zingizning faoliyat sohangizda juda zo’r va tajribali bo’lsangiz ham, buni faqat portfoliongiz bilan isbotlashingiz mumkin.

Tasavvur qiling mijozga nolinchi reytingga ega bo’lgan va hech qanday portfolioga ega bo’lmagan frilanser yozmoqda. Loyihani sizga ishonishi dargumon. Hatto eng soddasini ham.
