    Aici este cursul pentru care am nevoie de transcript: Transcriptul se va realiza in limba romana, cu diacritice si se va respecta întocmai structura cursului. Se va rescpecta impartirea pe capitole si subcapitole si se vor folosi stiluri corespunzatoare ( Title, Heading, Subheading, etc. ) pentru a se putea genera automat un cuprins. De asemenea, se vor folosi formule matematice ( acolo unde este cazul ), iar textul va fi formatat in asa fel incat sa fie lizibil si usor de urmarit ( fiecare video va începe pe o pagina noua, intre 2 capitole se va lasa o pagina libera, etc. ). Este de preferat ca textul să fie scris în Overleaf, dar se acceptă și Pages, Word sau Google Docs. In plus, este foarte importanta

    *Only for Romanians* Am nevoie de o persoana care sa imi facă prezentări PowerPoint după un manual de informatica. Prezentarile vor reprezenta cate un capitol din carte. Ideile se vor sublinia de catre mine (nu se va adauga tot). Se vor adauga propozitii sau cuvinte cheie in prezentare. Proiectul consta in adaugare si formatarea textului in pagina (exista un template custom care se va folosi pentru prezentari). Este vorba de un proiect pe termen mediu spre lung (mai am 2 carti care urmeaza sa fie convertite in prezentari). Va rog sa includeti pretul/slide in descrierea dumneavoastra (inca nu se cunoaste numarul exact de slide-uri, dar este vorba de o carte de 230 de pagini)
