Why this one

Where this actually takes you

SQL is the single highest ratio of usefulness to learning time in tech. Analysts, testers, marketers and developers all need it, and most only half-know it.

Data Analyst

Answering business questions with queries and dashboards.

Database Developer

Owning schemas, queries and performance.

Reporting / MIS Executive

Very common in Indian mid-size companies, and remote-friendly.

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

Querying data

From zero to genuinely comfortable writing SQL against real tables.

  • Relational thinking: tables, rows, keys, relationships
  • SELECT, WHERE, ORDER BY, GROUP BY and aggregate functions
  • Joins — inner, left, and the mistakes everyone makes with them
  • Cleaning messy data: nulls, duplicates, types, dates
You finish withFifty real business questions answered in SQL against a live dataset.
2 Month 2 · Core

Designing and changing data

Not just reading a database — building and maintaining one.

  • Schema design and normalisation, and when to deliberately break it
  • INSERT, UPDATE, DELETE, transactions and why they matter
  • Constraints, foreign keys and letting the database protect your data
  • Subqueries, CTEs and window functions
You finish withA schema designed from a written business brief, built and populated.
3 Month 3 · Advanced

Performance and reporting

Making it fast, and turning queries into something a manager can read.

  • Indexes: what they do, when they help, and when they hurt
  • Reading a query plan and fixing a slow query
  • Backups, migrations and not losing data
  • Building dashboards in Metabase from your own queries
You finish withCapstone: a performance investigation plus a working dashboard, presented to a non-technical audience.

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.

PostgreSQLMySQLSQL joins & window functionsDBeaverExcel / SheetsMetabase

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

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.
