Why this one

Where this actually takes you

Every integration, mobile app and AI product runs on APIs. Designing one badly is expensive for years, so teams pay for people who do it properly.

Backend / API Developer

Owning the service layer of a product.

Integration Engineer

Connecting systems that were never designed to talk.

Technical Consultant

Advising on how systems should fit together.

The syllabus

Three months, foundation to advanced

12 weekends. 24 live sessions. Each month ends with something you built and can show — not a certificate of attendance.

1 Month 1 · Foundation

API fundamentals

What an API is, what makes one pleasant, and what makes one hated.

  • HTTP in depth: methods, status codes, headers, idempotency
  • REST principles — resources, nouns, and consistent shapes
  • Reading and using someone else's API with Postman
  • JSON, serialisation, and designing a response nobody has to guess at
You finish withA written critique of three public APIs — what they got right and wrong.
2 Month 2 · Core

Building and documenting

Your API is a product. Its users are developers.

  • Building a REST API with FastAPI: routing, validation, error contracts
  • Pagination, filtering, sorting and bulk operations
  • OpenAPI/Swagger documentation generated from the code
  • Versioning, and how to change an API without breaking its users
You finish withA documented, versioned API that another student can integrate against blind.
3 Month 3 · Advanced

Security and scale

The parts that matter once real traffic and real data arrive.

  • Authentication and authorisation: API keys, JWT, OAuth2 flows
  • Rate limiting, abuse prevention and the OWASP API risks
  • Webhooks, retries and designing for failure
  • Caching, performance and monitoring in production
You finish withCapstone: a secured, rate-limited, documented API consumed by a real client app.
Who teaches you

Your mentor

Someone who does this work professionally, teaching the way it is actually done — not reading from a slide deck.

Also teaches: Backend Development, Databases & SQL, Data Engineering, AI & Applied Machine Learning — take both and you learn one connected system, not two disconnected subjects.
What you walk out with

Tools you'll actually have used

Not a reading list. Every one of these is used in a graded exercise during the course.

RESTFastAPIOpenAPI / SwaggerPostmanJWT & OAuthWebhooks

A portfolio, not a certificate

Three graded pieces of real work — one per month — plus the capstone. This is what gets you the interview.

A certificate from Snow Stag

Issued on completing the assessment and attending enough of the course to have earned it.

Interview preparation

Mock interviews, CV and LinkedIn review, and how to talk about work you have actually done.

The fee

Deliberately small, on purpose

Mentors volunteer their weekends. The fee covers what it costs to run the course — nothing more. It is charged monthly so nobody has to find a large sum upfront.

1

Apply

The form takes under a minute. No payment at this stage.

3

Money should not be the reason you don't apply. If even this is out of reach, say so on your application. We would rather find a way than lose someone who wants it.

Before you apply

The honest answers

No. This course starts at foundation level and assumes nothing. What you do need is twelve weekends of genuine attention — that is the real entry requirement, and the one most people underestimate.

No. Classes are live and online, so you join from wherever you are. The whole point of these skills is that the work travels even when you do not.

That is exactly who this is built for. Classes are Saturdays & Sundays only, plus practice time in between. Nothing happens on a weekday.

Every session is recorded and yours to keep. But attendance is tracked — people who watch recordings instead of attending consistently do not finish, and we would rather tell you that now.

Yes. ₹3,000 in total across 3 months, paid monthly. No registration fee, no material charges, no exam fee. Note that fees are not refundable, so please be sure before you commit.

We do not guarantee jobs, and be careful of anyone who does. What you get is a portfolio of real work, a certificate, mock interviews and CV support. The hiring decision belongs to employers.

Dates are being confirmed now. Applying puts you on the list first — applicants hear the start date before it is announced publicly.
