Description
I used to think that performance of the backend depends on the application logic itself. However, there are many other factors that play a role in overall quality and performance of the application. Networking, connection establishment, security, backend communication,Â protocol serialization, intermediaries and much more.

Often debugging the app if you have the source code allows the developer to zone in to the problem and identify it, However most of the time as an engineer you either donâ€™t have access to the source code or its time consuming to debug a complex app. That is why in this course I present you with some tools I use to analyze the backend application performance and provide a good guess and what might be the problem without stepping in the code. Often known as black box testing.

If your application is a web application that is consumable through a browser, devtools allow us to pretty much inspect all traffic going out from the app and can tell us so much about the app. If the app is not available in the browser we will then demonstrate MITM proxy which is a proxy that intercepts HTTP traffic and log it, this way we can inspect requests and see which of those are the culprit. Finally, if the app uses a protocol that isnâ€™t HTTP intercepting it with a proxy becomes little tricky, so we will use both tcpdump and Wireshark to capture low level packets and see our requests this way.

This course is designed for developers and engineers who have built backend and frontend applications and would like to take their skills further. This course is intermediate to advanced and it is recommended that students have a background in networking and backend fundamentals both of which I have courses for.

Who this course is for:

My name is Hussein and I’m a software engineer. My software journey started around 1998 when my uncle gave me a book titled `Learn Programming and Visual Basic 2.0`. That book made me realized that I enjoy the craft of building software. Using every medium available I would talk about software in a form of bulletin boards, blogs, books, courses, podcasts, and videos.These days I run a YouTube channel where I cover software engineering topics with a focus on backend tech. I discuss databases, proxies, security, networking, protocols, and programming. I also cover recent news and current events in the field of software.I specialize in the field of geographic information systems (or GIS for short). Since 2005, I helped many organizations in the Middle East implement Esri GIS by designing and building mapping apps to streamline their workflows. I wrote five books on Esri’s technologies and I've been a principal engineer there since 2015.Using software to solve interesting problems is one of the fascinating things I really enjoy. Feel free to contact me on my social media channels to ask questions or share interesting problems. I would love to hear it!
