These videos are genuinely both entertaining and informative while being straight to the point. Looking forward to more system design in the future. Keep up the good work!

[@Codebagel]

Thank you! Excited to get to the system design content!

what a username

[@dwainhanlon1988]

This feels like more of an intro to backend engineering, rather than a roadmap.

[@myonlylovejesus887]

exactly, he didn't go into detail how much programming should we learn. how much deeper we should go into api. nothing.

[@muertaqueen]

Ikr. Just click bait. All this info is entry level.

[@gadgetboyplaysmc]

I clicked because the title promised a lot haha. But it kinda oversimplifies the backend a bit too much. I expected more. I feel like beginners gloss over what makes backend hard. No offense tho. What I got from the video is all know how to code + database (store data woohoo)api (serve data woohoo) + tests + system design (I kinda wish you talked about a VPS, CDNs, SES, or even just S3 here). There's definitely a lot harder parts I wish I learned better back then: • REST and the HTTP Protocol • Parts of the Request-Response lifecycle (You should definitely learn how Request and Response headers work or how cookies pass through between the browser and your backend, or how you can redirect browsers using the Header) • Implementing your auth from scratch (JWTs vs Sessions) - This is probably super fundamental and I did not see it talked about here at all. Implementing UN/P and OAuth2. • Setting up a database migration system (actually enlightening as hell when you first learn it) - migrate:up, migrate:status, migrate:down, etc. • Backend Architecture - Actually knowing how to vertically/horizontally slice your backend codebase into layers. Appropriately of course. DDD is a must-learn for intermediate developers (a bit overkill in some projects but learning these concepts changed my life). Learn what DAOs, DOs, Repository Pattern, Entities, Aggregates, DTOs, etc. are. You don't need to apply all the concepts but just pick what makes sense. • And yeah, Systems Design probably. Like maybe just an explanation of why you'd probably need S3 (because you can't store blobs in the database, which is a very common usecase for saving pictures, videos, pdfs, etc), and a bunch of other cloud services. • A little bit of CI/CD as well. GitHub actions, making a deployment to a VPS upon pushing to the repo. There's a ton of uncomplicated examples out there (Kamal for example). • A bit of Linux and VPS skills as well: NGINX or Caddy, TLS, adding a domain name, PM2, etc. Deploying a node application on a VPS is a grueling, but valuable learning effort that platforms like Vercel just spoonfed to most devs nowdays.

[@Kurauone__]

This is very helpful. Can you recommend sources for learning these concepts? I would like to study them on my own.

[@Codebagel]

I appreciate you taking the time to leave a detailed comment! Yeah you’re right about everything, but it’s very hard to fit all of these topics into a video meant to serve as an introduction. I will of course expand on these topics in later videos, but I personally feel it’s hard to understand these concepts without having the grasp of the fundamentals of backend engineering. For example, how can you understand slicing your backend codebase into layers when you don’t even know what a backend codebase looks like? TL;DR - Very good points, but I feel these advance concepts are more suited for a more advanced video - this roadmap is meant to highlight stuff for people looking to just get started with backend engineering.

[@Kurauone__]

i started with javascript, coded 1.5 years in it, then moved to python bcs i lost my job, now i find python easier then javascript/typescript. but in general my preferred way is first to learn JS/TS and then move to full stack

[@DonaldFranciszekTusk]

Being a junior developer can be very overwhelming. Which IT branch should I choose? Web, gaming, AI, science, mobile, hardware? Which path should I choose? Backend, frontend, forehand, fullstack? What technology? .NET? React? Next.JS? Django? Oh, something new has come out, I'll check it out too. What languages to practice? C, C++, C#, Java, Python, JS? Or maybe TS, maybe some Go, Rust, Carbon etc.? Any Python libraries? One roadmap? Second? KZbin? Books? Courses? Documentation? ProjectOdin? Leetcode? AdventOfCode? Kaggle? What else? Maybe design patterns and paradigms? Terribly frustrating and mentally damaging. It is a scandal that neither universities nor companies want to help young people enter the market and become good, happy employees. (I appreciate how many opportunities the IT industry offers, how interesting it all is, but we are not robots to understand it all.)

[@jirisuster6165]

My "struggle" with backend after 2 years of working as a backend dev mainly consists of just the sheer number of technologies I have to be familiar with beyond surface level. Headers, migrations, auth, caching, redis, redis clustering, azure, docker, containers, kubernetes, logging, elastic, kibana, grafana, jaeger, Java - maven/gradle, nexus, Linux, "insane" db designs, security, microservice architecture, kafka, holy **** kafka, dealing with bad data, testing, fkin java 6 legacy systems build with ant or smth ffs, postman/curl, Prometheus, Jenkins haha more like Hudson. Sometimes even understanding the hierarchy of your own company, zero documentation beyond detail design with no understanding what the thing you're writing is even supposed to do, very busy seniors that always answer stuff after 8pm, meetings where you have exactly 0 idea what's even being discussed, outdated internal wiki... But I love it honestly because even though I'm lost most of the time, the high you get when you overcome something like this is insane

[@Nautyy9]

I think the goal is to become someone useful and not just someone versed in academic programming. Java and golang… Even google doesnt use golang that much. And I remember trying to learn Clean Coders stuff for java. its like a talmud 6000pages long. Id still take something useful like js or python over java and golang.

[@Codebagel]

@@aristonsaizoxic1048 I started learning with Python too! There’s nothing wrong with Python at all, it’s one of the most used languages for a reason! I just recommend that after you feel comfortable with Python, you should take a quick look at a language like Java (or C if you’re brave) to understand a few things that Python does automatically for you. You may work with another language in the future so it’s good to know those things. Keep up the great work, you’ll be an excellent engineer!

Is it worth going full stack in this day and age?

Yes 100%. Every engineer should be full stack somewhat. Backend engineers’ work impacts the frontend, and vice versa. Also gives you more job opportunities, especially at startups where all engineers are required to work on all parts of the stack.

Honestly, I would rather not recommend anyone start with Java if they're doing backend. Java backend usually means Spring and learning Spring won't teach you as much about the backend as something like Golang where you have to build a lot of stuff yourself and learn how to do things.
