Data Engineering, Analytics & Business Intelligence
Data Cleaning & Transformation
We fix duplicates, inconsistent formats and missing values in your data, then reshape it into analysis-ready tables that produce trustworthy reports and models.
Overview
Why it matters
for your business.
Customer names spelt three ways, dates stored as text, GST numbers with stray spaces, product codes that changed last year: dirty data quietly distorts every report built on it. We profile your datasets to measure these problems, agree correction rules with the people who own the data, and fix issues systematically instead of by hand.
Transformation follows cleaning. We standardise units and codes, deduplicate entities, join related tables and create derived fields such as customer tenure or margin. Every rule is written as version-controlled code, so the same logic runs again on next month’s data and anyone can see exactly how a figure was produced.

- Data profiling report with quality issues quantified

Reports you can trust
Consistent, deduplicated data removes many of the errors that make managers doubt dashboard figures.

Cleaning rules run automatically on new data rather than being redone manually in spreadsheets each cycle.
Transparent lineage
Documented transformations show auditors and analysts how each derived field was calculated.

FAQ
Common
questions.
Something else on your mind? Ask us directly.
Who decides which version of a duplicate record is correct?
Your data owners do. We propose matching and survivorship rules, such as preferring the most recently verified address, and show examples. Ambiguous cases go to an exception list for your team to resolve rather than being merged automatically.
Will you change data in our source systems?
By default we clean data in a separate analytics layer and leave source systems untouched. If you want corrections written back to your ERP or CRM, we plan that as a controlled step with backups and sign-off.
