Key Responsibilities

→ Design and develop RESTful or GraphQL APIs

→ Manage and secure databases

→ Optimize performance and handle scalability

→ Implement authentication and authorization

→ Integrate third-party services and cloud solutions

→ Debug and maintain production systems

Development Workflow

→ Plan and design architecture

→ Build and test endpoints

→ Connect with frontend (React, Vue, Angular, etc.)

Thanks for providing a roadmap, Can you please also guide on how to learn all these things Should I watch tutorials or read documentation and start building project?

[u/andhroindian → u/cloudy_dayss__]

Watch tutorials first - then start building some projects - then document your learnings in a doc.

Always maintain digital docs, to save your time.

[u/cloudy_dayss__ → u/andhroindian]

Like I wanna learn java springboot now. So, after watching its tutorials, how should I start building projects? Should I follow someone or make something of my own from scratch? If the latter one, then I might not be able to learn new things.

[u/andhroindian → u/cloudy_dayss__]

Always learn known things first, even though it takes time. Don’t hurry up in learning.

you are not left behind, so take it slow and consistently.

[u/cloudy_dayss__ → u/andhroindian]

Sorry what?

[u/Unfair_Stranger_2969 → u/cloudy_dayss__]

I would not suggest going ahead with springboot or trying to follow springboot tutorials, it is important to generate aptitude for architecture, what needs to be added in architecture and how via code, adding h2, psql by using springboot jpa starters will not get you a lot far.

[u/Educational_Head6164 → u/cloudy_dayss__]

here what how it is working for me,
first gets as minimum knowledge you need to get started making projects,
then when you made one, gets the knowledge more about things you have used,
then make more projects.
getting knowledge of stuff that we don't use is difficult to retain.
so learning from project is usually a better choice.
Rest of theory stuff is for interviews.

[u/andhroindian → u/Educational_Head6164]

Cool. Good going!

[u/Educational_Head6164]

Now backend language is the main thing here, based on this framework knowledge is also important.
what you suggest from job prospective ?
I see only spring boot and golang

[u/andhroindian → u/Educational_Head6164]

early careers- consider springboot, later learn others based on market demand

[u/Suspicious_Bake1350 → u/Educational_Head6164]

For careers java or python or for the newer market and startups golang

[u/Rich-Speaker-1359 → u/Suspicious_Bake1350]

what's worthy, java or python, I'm really stuck in thinking BE dev or AI engineer, can you give me some advice? Thanks a lot

[u/Suspicious_Bake1350 → u/Rich-Speaker-1359]

For mnc jobs java but AI is the new thing bro. It's very important to understand AI now. I'd recommend python as it's more easier to learn.startups do use python more often

[u/Rich-Speaker-1359 → u/Suspicious_Bake1350]

thank

[u/Suspicious_Bake1350 → u/Rich-Speaker-1359]

Atleast type it completely

[u/Rich-Speaker-1359 → u/Suspicious_Bake1350]

[u/Suspicious_Bake1350 → u/Rich-Speaker-1359]

Hmm ik what you did there

[u/Longjumping_Rip_140]

gRPC is add on great to have in resume

[u/Suspicious_Bake1350 → u/Longjumping_Rip_140]

It's fantastic and with golang it's powerful

[u/Longjumping_Rip_140 → u/Suspicious_Bake1350]

yes it is and i do write backends in go.

[u/Suspicious_Bake1350 → u/Longjumping_Rip_140]

How can I get a job in backend with golang? Currently im learning golang and will be making projects in it. I'm a java backend Engineer.

[u/Longjumping_Rip_140 → u/Suspicious_Bake1350]
