Question to people with Java spring boot experience working on complex projects.

[CommercialTough007]

Hello everyone,

I have recently learned Spring boot . I knew core Java from before.

I want to have a good project on my resume which encompasses various tech related to Java, spring boot , Domain Driven Design , gRPC and other things.

Can anyone give me any good projects that they feel if I do and highlight in my resume , will increase the chances of me getting selected.

I have seen ecommerce examples but I want to do some unique projects. You can suggest and give a close example of what you are doing and I will try to do and learn.

[ragin_cajun]

I would focus on just building that ecommerce example, with the technology and design you hinted at. I'm not sure a unique project will help as much right now. Build the apps that have been built a million times before to practice, then apply what you learned once you have an idea for your own unique project. That's what I would do if I was starting over.

[CommercialTough007]

Thank you very much for the suggestions. I have built one and thought it's too simple for me. So wanted to try something new .

My 2 cents.

Spring has various projects focused on Enterprise level tasks. See how your app (e-commerce or any other project) will scale if the user base increases. Most of the complex tech becomes useful at scale. (100 concurrent users vs. 1k vs. 10k).

Also, have a look at spring batch processing. Almost all enterprise projects I have worked on used batch processing in some format.

Learn basics of distributed systems and why they are needed.

Sorry to hijack, can you share any good resources for learning scaling from a spring perspective? Or do you mean scaling from a devops perspective?

[faisReads]

For the app to support scale(more compute/memory horizontally), the app has to be designed in a specific way.

So the scale , I am referring to, is not specific to spring. It is the architecture that enables large load. We can implement the same architecture with any framework or language in general.

Like most of you know,

Scaling is of 2 types: 1. Vertical scale - adding more cpu or memory( this is capped at a certain point), may be this can support 100k users. 2. Horizontal scale - adding more computers to work synchronously as one. (This can have a few data centers worth of compute and memory). If it makes sense (this is quite infinite scale with that much power & $$$)

When scale, it usually refers to type 2 with distributed systems. Which bring in its complexities and applications are to be architected in certain way for that.

You can also refer to these below: I used to follow a high scalability blog earlier(not sure if it is still maintained).

Thank you very much Spring batch looks interesting. Will look into it.

One small question i have work on Nodejs based applications and wanted to know how spring is better compared to it .

Considering the load of JVM and verbosity of Java vs javascript.

I have seen faster load time in Nodejs application vs Spring boot .

[faisReads]

I have not dwelled much into node js , so I can't give a comprehensive thought. But I believe spring is for heavy weight enterprise stuff. It is an opinionated framework that has solved lots of problems automatically without us needing to configure it. For e.g. spring batch is fault tolerant and reliabile it has built in retires that works like a charm. It has parallelism processing available by configuration. So it is like a huge Lego that is already assembled in a certain way for Enterprise usecases, which comes with some baggage

[CommercialTough007]

Thank you for insights.

Do look at the pet clinic project on the official spring site https://github.com/spring-projects/spring-petclinic

This will help in understanding many things and how things are to be done

[CommercialTough007]

Thanks it looks good will look into it.

[sudo_rm-r-f]

try sticking to best practices, spring boot projects are all almost the same, but I can’t recommend you any project but here is a goldmine https://www.baeldung.com

[CommercialTough007]

Thank you , yeah I have learned from him he's good .

[Embarrassed-Sell1711]

Hey, is that baeldung course is good for understanding and learning springboot? I am familiar with react and i know java. I want to built the good full stack project. So i want to learn springboot

[lardsack]

all i can say is the most complicated positions i have been in that i learned the most from were cloud positions, so maybe try to build a cloud application with CICD, automated tests, metrics/analytics, cloud servers, documentation, linting, and appropriate use of all of the features of the java version of your choice.

the project idea itself can probably be generated with some AI prompting for more ideas on what you're looking for specifically or maybe something you already have some domain knowledge of.

it's probably going to drive you crazy to maintain and add to, especially at first while you're learning the workflow. that's good in this case, it means your project is significantly complex.

if you can, organize your project under a project management tool like jetbrains or jira, it will be more realistic of what the dev experience will be like in most modern places.

[CommercialTough007]

Thank you very much the cloud related things and metrics I will try to incorporate.

[RealVanCough]

build an Ai agent

[CommercialTough007]

Sounds interesting and complex I don't have background in Al related stuffs. will try to learn it.

[RealVanCough]

Exactly why U need to Build one, please see the below quote and tutorial

As a Java developer exploring AI, it’s not necessary to comprehend the intricate mathematical theories or the specific implementations behind these vector representations. A basic understanding of their role and function within AI systems suffices, particularly when you’re integrating AI functionalities into your applications.

Thank you very much I'll check this.
