What Students Are Saying About Pragmatic REST APIs

As engineers we solve problems, this course gives you a deep understanding of Rest and HATEOS, but more importantly, to me, is the pragmatic approach to problem solving and the iterative approach to resolving issues. The process that most of us go through every day is silent but Milan eloquently explains his thought process. The biggest challenge I face is the evolving .NET landscape and completing things in a timely manner. When you spend a lot of time involved with digital transformation it's easy to lose pace and fall behind. These courses keep me current and allow me to provide solutions that are forward thinking. This course catches you up on modern approaches from a deep engineering perspective. The lessons are organized and presented perfectly. This young man has skills! As far as my recommendation goes it is without hesitation that every single one of Milan's courses and instructional videos should be studied when time permits. I benefit every day from every one of his lessons as I seek to become the best .NET developer I can be.

I'd consider myself an intermediate developer who has mainly been exposed to the Microsoft ecosystem. I've been wanting to learn more about properly writing APIs as I think about moving to another SPA away from Blazor. This course has been a great place for me to learn and expand my knowledge. Not only is Milan clear and knowledgeable but I love his way of starting basic and going back and refactoring rather than jumping in the deep end. Add to that his meticulous approach and you've got yourself one hell of a teacher. I also love the things he teaches me alongside the core elements of the course. These have been a real valuable lesson for me. I'm following this course as I try and rewrite our internal app for work. Milan, thank you, you're making this process so enjoyable.

I discovered Milan about 1.5 years ago and I have admired him greatly since then. He is a perfect teacher for me, both in terms of his mastery of the subjects and his way of explaining. In addition to these, he is a very kind and understanding engineer. I take all his courses when I have time and follow them meticulously. I definitely recommend his courses to everyone, as they have supported me in the development of my personal software career, the change of my perspective and most importantly, in walking to the point I want to be. I am sure you will not regret it!

This is by far the best and the most comprehensive REST APIs course I have seen. Milan explained all the aspects or REST, how to apply it in real-world applications, including HATEOAS which is missed in 90% of REST APIs. You will see how HATEOAS can be really useful to drive the application state. What is really fascinating is that Milan showed a real client Web UI application, as it integrates with the built REST API. This stands out this course among the others. I really like how Milan explained all the decisions throughout this course in a pragmatic manner, explaining what works and what are the trade-offs in the real-world. I can recommend this course for everyone, after watching you will be ready to start building production ready REST APIs. You will also learn advanced topics for fetching data, caching, authentication and authorization, how to integrate with external APIs like GitHub and Patreon. And finally how to write all sort of tests for the APIs and how deploy your apps to Azure through CI/CD pipeline.

I've been in the development world for years, and this REST API course has been an absolute game-changer for me. The best thing about this course is its comprehensive and practical approach—it not only covers the fundamentals of REST, from Roy Fielding’s groundbreaking work to real-world examples, but also delves deep into advanced topics like HATEOAS, API versioning, caching strategies, and robust deployment practices. Before taking this course, my biggest challenge was designing APIs that truly adhered to RESTful best practices. I struggled with creating intuitive URL designs, managing error responses effectively, and securing endpoints properly. The course's detailed modules on CRUD operations, validation, error handling, and security have completely transformed my approach, bridging all those gaps with clear, hands-on examples. What really sets this course apart is how it complements the other top-notch courses by Milan, namely Pragmatic Clean Architecture and Modular Monolith Architecture. Each course brings its own unique insights and practical strategies, forming a complete toolkit for modern web development. While the REST API course sharpened my API design and development skills, the other courses have empowered me to build maintainable, scalable, and robust systems overall. With the insights gained from this course, I'm now confident in building APIs that are scalable, secure, and user-friendly. Every aspect—from thorough testing and effective error handling to seamless deployment and comprehensive documentation—is covered in detail. I would highly recommend this course, along with the other two, to any developer looking to elevate their skills and build better, more resilient Applications and APIs. Finally, this course only leaves me in greater appreciation and awe for Milan's patience, knowledge and reasoning. Looking forward to more courses just like this one, Milan. Fantastic content as always!
