From Zero to Full-Stack – Java Road Map
These are my thoughts about the Programmer roadmap, based on the knowledge from the internet and my experience.

Who is a full stack developer?

A universal developer who can:

  • works in frontend and knows frontend technologies
  • can design API and work in the backend, sometimes can’t make super optimizing programs, but these programs can work fine
  • can use and display databases
  • has basic knowledge of architecture, testing, security, Linux, CI / CD

it’s simple, can work in all areas

Areas

  • Frontend – all technologies running in the browser, generally written in JavaScript/TypeScript or written in different languages and use WASM compiler to convert to WebAssembly
  • Backend – all technologies running in the servers or cloud ecosystems (AWS, Amazon, Google, etc)
  • DevOps – ensures the functioning of servers and software
  • Security
  • Architecture
  • Database relational and NoSQL

T-Shaped Skills

The developer can’t know everything about all IT disciplines. The knowledge in the full-stack developer is like a T shape letter.

  • find someone who will be able to view your code
  • use version control systems from the beginning
