Java bilan yangi bosqichga! 🚀

MAANG’ga tayyorgarlik ko‘rayotib, ko‘p o‘ylab qolaman:

Balki avval O‘zbekistondagi xalqaro IT kompaniyalarda tajriba to‘plash kerakdir? Seniorlardan o‘rganib, yuqori load’li loyihalarda bilimlarimni sinab ko‘rsam, qanday bo‘larkin?

Ha, Python bilan ham xalqaro IT kompaniyalarga kirish mumkin. Lekin aksariyat hollarda Data Analytics, Data Science yoki ML yo‘nalishida. Bu sohalar ham juda istiqbolli, lekin data yig‘ish, tozalash, normalizatsiya kabi yoqimsiz jarayonlari bor. Menga esa backend’da API’lar chiqarish, biznes logika yozish va yuqori load’ga bardoshli tizimlar qurish yoqadi. (Kelajak data bilan babir)

Shuning uchun 5 yillik Python tajribamdan so‘ng ikkinchi til sifatida Java’ni tanladim. Bunga O‘zbekistondagi xalqaro IT kompaniyalar va banklarda ko‘proq shu til ishlatilishi sabab bo‘ldi. Kelajakda MAANG’ga topshirishdan oldin kamida 2, 3 yil xalqaro IT kompaniyada tajriba orttirishim kerak degan qarorga keldim.

Shunaqa gaplar. Xullas Open to work for Junior Java position! (CRUD API’lar yozganman, Spring Boot bilan tajribam bor). 🥰 (sharing is caring)

Python --> Go --> VueJs --> Java = SWE🤷‍♀️

p.s) Fikrlariz qanday? ⬇️

Advanced ORM | Django'ning foydali expression'lari haqida 💡

Deactivate unused apps and middlewares 🗑

Agar siz Django'ni faqat API sifatida ishlatayotgan bo'lsangiz, default holatda Django-da ba'zi keraksiz app'lar yoqilgan bo'ladi. Masalan, Sessions va Messages DRF'da foydasiz, lekin resurslarni sarflaydi va ishlash tezligini pasaytiradi. Kamroq middleware ishlatsangiz, har bir so‘rov tezroq qayta ishlanadi

What is the difference between Software Engineers and Software Developers? 🤷‍♀️

P.s) Channel renamed:
