Menga ham shu platforma yordam bergan. Men Amazonga apply qilmaganman, qolgan hamma kompaniyalarga apply qilgan paytimda. Amazon mani leetcode va profilinmi yangilaganim sababli topgan. 2022-yil yanvarda ozlari linkedin orqali chiqishgan. O'sha payt, 1 oydan keyin qaytib kelin deb javob berganman, va qogan FAANGlarga topshirib chiqanman

Amazon-dagi product/feature development lifecycle

Amazondagi "Working Backwards" processi haqida eshitgan bolsangiz kerak. Qisqacha qilib etkanda yangi product-lar foydalanuchilarga topshirishga tayyor bolgandek tasniflab beruvchi document/reklama bilan boshlanadi - "Product release/frequently asked questions"(prfaq). Bu document product-teamda foydalanuvchilar bilan togridan-togri muloqot qilib muammo va tajribalarini organish jarayonida yoziladi. Ular boshliq va project-management ga pitch qilgan holda texnik detallar va resurslarni aniqlashtirish uchun ishni topshiradi. Management-ning asosiy fazifasi - mahsulotni prioritetini belgilash va pul/vaqt/odam ajratish. Ish injenerga kelganda asosan deadline ham belgilangan boladi. Shuni hisobga olib texnik documentlar yoziladi.
1 High-level design - system behavior/depedency/componentlarni ozaro bogliqligi. Bu yerda ochiq savollar topiladi va product/project managerlarga aniqlashtirish uchun yuboriladi.
2 Low level design - componentlar nima va qanday ish qilishi. Qoshimchasiga Ish qismlarga bolinishi va vaqt olchamlari keltirilib otadi. But qismda ham noaniq detallar project/product ga yuboriladi.
Kod yozishga kelganda deyarli hamma narsa ochiq-oydin bolishi kerak. Shunchaki foydalanuvchi koriladigan soz/matnlar tech-writerga yuborilib aniqlashtiriladi.
Mahsulot tayyor bolgandan keyin foydalanuvchiga ochiqlanmaydi, balki application security engineer uchun review tashlanadi. Bu kod-yozish paytida parallel olib boriladi. Odatda. Va review tashlangandan keyin security injener threat modelling-dan otkazib, testlar va prooflarni belgilaydi (talab etadi), pentest belgilashi ham mumkin.
Bundan keyin product minimal operational readiness bilan tayyor bolib foydalanuvchiga ochiqlanadi. Lekin toliq "operation readiness review" baribir kerak boladi. Bu boshqa injenerlar ham kerak bolganda tizim qanday ozini tutayotganini tushinib muammolarni monitor va hal qila olishi uchun majburiy protses.

2 haftalik ta'tilim ham tugadi. Ta'tildan oldin Shokhrukh (Principal Engineer, http://Booking.com/) aka podcast/interview-larida maslahat bergan kitobni buyurtma bergan edim - https://www.oreilly.com/library/view/the-staff-engineers/9781098118723/ Seniorlikka harakat qiladiganlar uchun ham foydali ekan. Agar tech-korxonada yoki senior/lead ro'llarida ishlab kelayotgan bo'lsangiz - ish davomida uchraydigan boshqaruv/tashkiliy muammolarga tasnif va yechim yo'llarini topa olasiz:
• Staff+ injener nima qiladi
• Yillarga joziladigan texnik-ish qanday boshlanadi. Moliyaviy qoplanish muhakama yo'llari
• Bir nechta jamoalarni qamraydigan texnik muammolar/maqsadlar qanday belgilanadi
• Qo'shni jamoalar(upstream/downstream dependent) va Project/Product/Design bilan ishlash va maqsadga erishish uchun kommunikatsiya uslublari
• Katta yangilikni foydalanuvchilarga chiqarishdagi marketing/operational/customer-adoption ishlari
Ayniqsa, qo'shni jamoalarga va project/product managerlar bilan ishlash, o'zaro bog'liqlik va masuliyatni bo'lishish haqida yaxshi keltirmalar mavjud. Kitob muallifi google-da staff enginer bo'lgan va FAANG -dagi ishlash tartiblarini ta'riflab ketgan.

Agar student yoki kareerani boshlang'ich yo'llaridagi ijnener bo'lsangiz, https://m.youtube.com/watch?v=i7tAak5t7Os interview/podkastlarini maslahat beraman. Nuruddin injener, product va project manager bo'lib ishlagan (Ozbekistondan turib Meta corp. product specialist bo'lgan). Hozirga IT-kompaniya asoschi-boshqaruvchisi, podkastda O'zbekistondagi imkoniyatlar, injenerlarga talab/taklif va product/project manager ishi haqida fikr-mulohazalarini bo'lishadi. Yani yosh kadrlar imkoniyati, ish-talablarini yoritadilar. O'z professional (de fua) yo'llarini yoritadilar (spoiler - har doim harakat qilish kere). O'zim yana bir bor amin bo'ldimki, https://superdispatch.com/ istedotlarni kashf etadigan korxona.

LLM, GPT va chatbot-ga kirish.

(3-minutlik material)

Amazon Q va ChatGPT ishlashini ko'rib chiqilaylik. Shunda ish o'rinlarimizni olmoqchi bo'lgan "AI" dushmani yaxshiroq bilib olamiz. Boshlashdan oldin - men ,ML/Data Science va AI larda chuqur
Ilmiy bilimlarim yo'q. Men dasturchi va Q-Servisini qurishda, bazaviy ML/AI tushunchalar, chatbotlarning arxitekturasi va ishlash printsiplarini o'rganganim bilan bo'lishaman.
Chatbotlarning o'zagi bu LLM - katta til modellari. Eshitgan bo'lsangiz kerak chatGPT 4 trillion token larga o'rgatilgan bo'lgan. Oddiy qilib etkanda token bu so'z + vektor, yani boshqa so'zlarga bog'liqlik darajasi. Misol "ilm" va "fan" so'zlari bir-birig mano jihatdan yaqin, va ko'p holarda birga ishlatiladi. Shunda LLM- da bu ikki so'z vektorlari ham "yaqin" qiymatlariga ega bo'ladi. LLM-ning So'z va Vektorlardan gap tuzish qobiliyati "Transformer Layerlar" dan kelib chiqadi. Ularni vazifasi ham oddiy - so'zlar ketma-ketligini grammatik, sinktatik va kontekst orqali bog'lash. Misol eng mashhur transformer layerlardan biri bu Attention layer - u so'rovdagi asosiy so'zlarni topishda va ularga weight ( o'lchov og'irligi ) beradi. Yana biri Embedding layer, so'zlarni syntaktik va semantik bog'ligini o'lchaydi( grammatika va kontekst). Chatgt-4 da 120 ta transforming layerlar ishlatilgan. Transformerlar Vektor parameterlari/o'lchamlarini boyitshdan tashqari, mavjudlarini ham to'girlab ketishadi.
GPT - generative pre-trained transformer - Tekst va unga o'xshash ma'lumotlar(misol kod) yaratishda LLM-dan foydalanib so'zma so'z bog'lanish tuzadigan arxitektura. Yani savolni ham parchalab o'qib, parchalab javob tuzadi. Misol: "eng kuchli kompyuter qaysi"
"Eng", "Eng kuchli", "eng kuchli kompyuter" va hakozo. Shu usulda u ikkilamchi, asosiy so'zlarni, ularning bog'liqligi, abstrakt/kontekst va hakozo parameterlarini yeg'adi. Va javob berishda ham so'zma-so'z ketma-ketlik tuzib har bir yangi so'zda transforming layerlarni yurg'izdirib chiqadi.
Shuning uchun ham chatbotlarda to'lov belgisi bu so'rov-javobdagi so'zlar/belgilar soni, chunki har biri uchun butun boshlik arxitektura yana boshidan ketma-ketlikda yurg'izdiriladi.
Chatgpt-ning texnologik innovatsiyasi ham shunda edi. Birdaniga javob berish o'rniga eng maqbul so'zlarni birin-ketin topish orqali gap tuzish. Shunda eng o'rinli so'zlar bilan ma'noli gap tuzish ehtimoli oshadi
LLM lar Foundation Model(FM) ustida qurilgan. Yani training paytida yeg'ilgan bilimlar, va inson aralashuvisiz bilim ustida bilim qurish orqali to'plangan token va vektor qiymatlarini ishlatadi. FM-lar Peta-bayt (million terrabayt) hajmdagi internet-tarmoqda mavjud bo'lgan informatsiya bilan o'rgatilgan. Har bir so'z uchun 120ta transformer algorithm-larni yurg'izish uchun kuchli kompyuterlar kerak. Lekin, xayriyatki, ular parallelashitiriladigan funktsiyalar. Parallel ishlash esa GPU xaritalar orqali juda oson. Va AI revolutsiyasi GPU va Data-Processing narxlarini oshirtirib yuborgan.


Keyingi qismda LLM-dagi topK topP va temperaturasi haqida gaplashamiz, chatbotlarning gallyutsinatsiya qilish sabablarini tushunamiz.
