Data Profiling Report

About this task

This biotech company (501–1,000 employees) is looking for a specialist Data Quality Analyst for a single piece of work with a fixed scope and a fixed price. Profiles a dataset for missing values, duplicates and outliers.

The work is too small to justify a hire and too important to leave to chance. It works in life sciences, where documents are versioned and reviewed in a fixed order.

The company prefers a person who can come to Saarbrücken for kickoff and the final review; the rest is remote. You choose your hours; nothing is scheduled except an occasional short call. About 2 hours a week should overlap with the team's day (CET).

What you deliver

• Profile the customer table and report missing-value rates, duplicates and invalid values by field.
• The finished deliverable in the agreed file format, with sources and assumptions listed
• A 20-minute walkthrough call, or a recorded screen share if you prefer
• A final note stating what was checked and what was left out of scope

How the work runs

• Day 1: kickoff call and access to the files
• Days 2 to 6: the work, with questions answered the same day
• Last day: delivery and a short walkthrough

Duration: 2 to 3 weeks. Accepted on the company's written OK. If something is missed, you fix it in the same week at no extra charge to either side.

Tools

How you get paid

• The company prepays Deftridge before your first hour, so payment does not depend on a late invoice.
• Deftridge pays you in EUR after the company confirms the hours or the deliverable. The payment date is written in your task agreement.
• You work as an independent contractor: you report your own income, and your recruiter sends the statements your accountant needs.
• You never chase the company. Questions about money go to Deftridge.
