Free chapter-wise notes
Downloadable PDFs per domain, ordered beginner to advanced. Yours on signup.
Real project work
Task briefs written from the work our engineering teams actually ship.
Human review
Every submission is read by a reviewer who approves it or sends specific notes.
QR-verified certificate
A unique certificate number and QR code anyone can verify publicly.
Pick the track that matches where you're heading
Each domain comes with its own chapter-wise study notes, a fixed set of technical tasks, and a reviewed final submission.
Full Stack Web Development
The whole path, from a Postgres table to a deployed interface. You will build one real application end to end — schema, API, frontend, authentication and deployment — and be reviewed on the seams between them, which is where full-stack work is actually hard.
Frontend Development
Build interfaces people can actually use. You will work in React and TypeScript, handle real application state, make the result accessible and fast, and deploy it where anyone can open it. Every submission is read by a KLS engineer who has shipped frontends to production.
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.
Data Science & Machine Learning
Work with real, messy data from end to end: clean it, understand it, model it, and say honestly how well the model works. The emphasis is on evaluation and on not fooling yourself, which is the part most courses skip and every employer cares about.
Cyber Security
Defensive security for people who build software. You will learn to find and fix the weaknesses that appear in real web applications, working only on code and targets you are explicitly authorised to test. The output of every task is a fix and a write-up, not an exploit.
IoT & Embedded Systems
Connected hardware, from the sensor to the dashboard. You will read real sensors on a microcontroller, get the readings to a server over an unreliable network, store them sensibly and show them to someone. The briefs come from the kind of systems KLS Tech Solutions builds.
A chapter-wise roadmap, beginner to advanced
Every domain comes with its own set of study notes as downloadable PDFs, ordered so each chapter builds on the last. Sign up and they are yours — you do not have to enrol in an internship, finish anything, or pay to read them.
Foundations
The language, the tools and the vocabulary. Written for someone starting the domain from zero, with nothing assumed.
- Set up a working environment
- Core concepts, explained plainly
- Your first working build
Building properly
Structure, patterns and the practices that separate code that runs from code someone else can work on.
- Project structure and conventions
- Working with data and APIs
- Testing and debugging
Production thinking
The parts most tutorials stop before: performance, security, deployment, and the judgement calls in between.
- Performance and security
- Deployment and operations
- Reviewing and being reviewed
Read the chapters, then apply them on the internship tasks in the same domain. The learning and the work sit in one place, and both cost nothing.

Questions students ask first
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.
Yes. Every certificate carries a unique number and a QR code linking to a public verification page. An employer can confirm it independently in seconds, without contacting KLS Tech Solutions and without needing an account.
Yes. The KLS Academy platform is released under the MIT licence, so anyone can read the code, run their own instance, or contribute to it. The KLS Tech Solutions name, logo and seal are not covered by that licence, and only certificates verifiable at academy.klstechsolutions.in were issued by us.
Most domains run for four to eight weeks, self-paced within the batch window. You set your own hours. The next task unlocks as soon as you submit the previous one, so waiting for a review never stops you working.
Typically a public GitHub repository, at least three screenshots of your working project, and a short written explanation of what you built and why. The exact requirements are shown on each task.
You get specific written feedback and can resubmit. There is no limit on resubmissions and no penalty for one. The aim is to get the work right, not to fail you.
Yes. Once your current internship is complete and your certificate is issued, you can start another in a different domain. Every certificate and offer letter you earn stays downloadable for good.
Anyone aged 18 or over can register. We ask for a date of birth because India's Digital Personal Data Protection Act, 2023 requires verifiable parental consent to process data belonging to under-18s, which we do not collect.
KLS Academy is the learning division of KLS Tech Solutions, an MSME registered organisation based in Bangalore, India, which builds IoT, SaaS and AI products.
