SQL portfolio builder for analysts

Problem Context

Early-career data analysts and engineers expect to learn SQL, data mining, and OLAP in internships. Instead, they spend 5+ hours weekly cleaning CRM data manually while managers handle all technical work. This leaves them with no real experience to build a portfolio, making them unhireable for better roles.

Pain Points

They waste time on repetitive manual tasks with no SQL/OLAP practice. Managers control all data prep, so they never touch queries or OLAP tools. Vague job descriptions promise training but deliver only dead-end tasks, leaving them anxious and stuck in low-paying roles.

Impact

Without portfolio-ready projects, they can’t apply for mid-level roles and risk long-term career stagnation. The emotional toll grows as peers with portfolios get hired. Over time, they fall behind in a job market that demands technical skills, making them less employable.

Urgency

They need to build a portfolio now to stay competitive. Every week without SQL/OLAP experience widens the gap between them and hired candidates. If they don’t act, they’ll remain stuck in manual tasks with no path to advancement.

Target Audience

Aspiring data analysts and engineers in their first 0-2 years of work, especially interns and junior roles. Also targets bootcamp graduates, self-taught learners, and career switchers who need portfolio projects to land their first technical job.
