Backend Development
Design and build the service behind the interface. You will model data properly, write an HTTP API other people can use, authenticate requests without inventing your own scheme, and make the thing observable enough to run. Python and PostgreSQL throughout.
What you'll be able to do
- Model a domain in a relational schema and justify the constraints
- Build a documented HTTP API with real validation
- Implement authentication and authorisation correctly
- Write tests that would catch a regression you actually fear

Common questions
Yes. KLS Academy is completely free. There is no enrolment fee, no certificate fee, and no payment of any kind at any stage. We never ask for card or bank details. The platform itself is open source under the MIT licence.
Yes. Every internship domain includes a full set of chapter-wise study notes as downloadable PDFs, ordered from beginner to advanced. They are free, they are yours to keep, and you get them the moment you sign up — you do not have to enrol, finish anything, or pay to unlock them.
Sign up with your name, email and date of birth. That is the whole gate. You can then read the chapter-wise PDF notes for any domain, and enrol in an internship whenever you are ready to start the project tasks.
Each domain has a chapter-by-chapter roadmap that runs from beginner to advanced. You read the chapters in order as downloadable PDFs, then apply them on the internship's technical tasks, which are reviewed by a KLS engineer. Learning and doing sit in the same place.
Enrol in a domain, share your offer letter on LinkedIn for verification, then complete each technical task. Every submission is reviewed by a KLS engineer. Your certificate is issued automatically the moment your final task is approved, at no cost.
