About this course

Integrating AI into applications is becoming a standard requirement for developers, but getting reliable results requires more than just asking a simple question. This course teaches you the foundational techniques of prompt engineering from a developer's perspective. You will learn how to structure system prompts, provide effective context, and guide model behavior to generate consistent, structured outputs for your applications. What you will learn: • Understand the core principles of prompt engineering and how large language models process text • Design robust system prompts that establish clear constraints and behaviors for AI models • Apply few-shot prompting techniques to improve accuracy and shape the format of generated responses • Manage context windows effectively to provide relevant background information without exceeding limits • Explore fundamental concepts of Retrieval-Augmented Generation (RAG) to ground AI responses in your own data • Format prompts to consistently return structured data for seamless backend integration. The course begins with essential terminology and basic AI concepts before moving into practical prompt structuring. You will progress through written exercises that demonstrate how to refine prompts for real-world development scenarios. Designed for beginner backend and full-stack developers who want to understand how to effectively communicate with AI models, this course requires no prior machine learning experience. Start reading today to build the skills needed to integrate reliable AI features into your software.

Really practical course on structuring system prompts and thinking about context window limits. The only downside is that some of the later lessons feel a bit rushed compared to the early ones.

Empecé este curso sin tener ni idea de cómo estructurar un prompt de sistema y ahora me siento mucho más seguro. Las explicaciones sobre las ventanas de contexto fueron claras, con ejemplos que realmente se pueden aplicar en proyectos reales. Me gustó especialmente la parte donde comparan distintos enfoques para dar instrucciones al modelo y cuándo usar cada uno. El ritmo es bueno, ni muy lento ni apresurado, y pude seguirlo mientras trabajaba en mis propios prompts. Terminé el curso con varias plantillas que ya estoy usando en el trabajo.

This course finally made prompt engineering click for me in a way tutorials online never did. The section on system prompts walks through real examples instead of just theory, and the breakdown of context windows helped me stop wasting tokens on unnecessary repetition. I liked how each lesson built on the last one, so by the end I was writing prompts that actually held up across longer conversations. The pacing felt right for someone with some coding background but no prior prompt engineering experience. I've already started applying the techniques at work and noticed a real difference in output quality.

Ce cours donne de bonnes bases pour écrire des prompts systèmes efficaces et gérer la fenêtre de contexte. J'aurais aimé un peu plus d'exemples concrets sur des cas d'usage complexes, mais dans l'ensemble c'est du contenu solide.

Solid breakdown of system prompts and context window management, though I wish there were more exercises on few-shot examples.

Sobrang linaw ng pagpapaliwanag tungkol sa context windows, parang may nag-eexplain sa'yo nang personal. Naging mas madali para sa akin gumawa ng mas epektibong prompts pagkatapos nito. Definitely gagamitin ko ang mga natutunan ko dito sa mga susunod kong proyekto.

Курс дал именно то, что нужно разработчику — не общие слова про ИИ, а конкретные приёмы написания системных промптов. Особенно понравился блок про управление контекстным окном, стало понятно, почему модель иногда «забывает» начало диалога. После прохождения сразу переписал несколько своих промптов на работе.

시스템 프롬프트 작성이 확실히 늘었어요

프롬프트를 막연하게 던지던 습관이 있었는데 이 강의로 완전히 바뀌었습니다. 시스템 프롬프트를 어떻게 설계해야 일관된 응답이 나오는지 코드 예제로 보여줘서 바로 제 서비스에 적용했어요. 컨텍스트 윈도우를 관리하는 부분이 특히 도움이 됐는데, 토큰이 왜 넘치는지 그동안 몰랐거든요. 퓨샷 기법으로 분류 작업 정확도를 눈에 띄게 끌어올렸습니다. 백엔드 개발자라면 꼭 들어볼 만한 실전 강의예요.

Ang galing ng paraan ng pagtuturo dito, sunod-sunod at hindi nakaka-overwhelm kahit baguhan ka pa lang sa prompt engineering. Natutunan ko kung paano talaga bumuo ng system prompts na gumagana at hindi lang basta-basta. Sulit na sulit ang oras na inilaan ko dito.

Хорошо разобраны основы системных промптов и работа с контекстным окном, но не хватило больше практики на реальных кейсах.

Llevaba meses peleándome con prompts que daban resultados inconsistentes en mi backend, y aquí entendí por fin la diferencia que hace un buen system prompt. La parte de gestionar la ventana de contexto me aclaró por qué algunas respuestas se cortaban o perdían el hilo. Las técnicas de few-shot vinieron con ejemplos de código reales que pude adaptar al instante. Lo mejor es que está pensado para quien programa, no para marketing, así que todo encaja con el flujo de un desarrollador. Mis integraciones ahora son mucho más fiables.

Malinaw at practical ang pagtuturo tungkol sa pag-gawa ng system prompts, sobrang naging madali para sa akin na intindihin ang context windows pagkatapos ng kursong ito.

Buen curso para entender los fundamentos de prompt engineering, sobre todo la parte de manejo de contexto. Me hubiera gustado un poco más de profundidad en los ejemplos de código para casos avanzados.

Clear, hands-on explanation of system prompts and context management that immediately improved how I write prompts at work.

O curso explica muito bem como escrever prompts de sistema eficazes e gerenciar janelas de contexto, dei um salto de qualidade no meu código depois disso.
