  • Design a warehouse schema that scales
  • Make slow dashboards fast with indexes and query optimization
  • Create stored procedures and triggers used in real production systems

Projects you build

Portfolio pieces you can demo.

Each project ships as real code you run locally, not slides you watch. Walk into your next review with something on screen.

01Project

An e-commerce analytics dashboard

Cohort retention, top SKUs, revenue by region, repeat-buyer rates. On a 100k real order dataset. The queries your growth team actually asks for.

PostgresSQL

You ship: A dashboard that answers real business questions with SQL you wrote, not a BI tool you clicked through.

02Project

A schema that scales to a million rows

Design from scratch for a SaaS app. Multi-tenant, indexed, partitioned where it matters. Defend every tradeoff in a system-design-style writeup.

Postgres

You ship: A schema diagram and SQL migration you can walk an interviewer through end to end. The thing juniors never get to show.

03Project

The 10-minute query you made 200ms

Take a slow dashboard query. Read the EXPLAIN plan. Add the right index. Prove it in milliseconds. Write up the before/after.

Postgres

You ship: A before/after benchmark and writeup. Recruiters and staff engineers both love this kind of evidence.

FAQ

Frequently Asked Questions

Do I need prior SQL experience?
No. The bootcamp starts from your very first SELECT and builds up. By the end you are writing window functions and tuning queries on 100k real orders.
Is this just PostgreSQL or general SQL?
Both. The fundamentals apply to any relational database, and the advanced modules lean on PostgreSQL-specific features like window functions, CTEs, partial indexes, partitioning, and stored procedures.
What dataset do I work with?
A 100k+ order Brazilian e-commerce dataset with real customer, order, payment, and review tables. You answer real business questions, not toy textbook problems.
Will this help in interviews?
Yes. Every module ends with the kind of question senior interviewers actually ask: join orderings, index selection, execution plans, and schema tradeoffs. You can walk into an interview able to defend your choices.
