Data Preparation & Engineering
Get your data AI-ready. Clean, structured, labelled data is the foundation of every successful AI project.
AI is only as good as the data it runs on. Most organisations have the data they need, but it is scattered across systems, inconsistently formatted, poorly labelled, or missing critical fields. We fix that. Our data preparation service covers the full pipeline: auditing your existing data sources, cleaning and normalising records, handling missing values and duplicates, creating labelling workflows, and building transformation pipelines that keep your data fresh and consistent. Whether you are preparing training data for a custom model, building a knowledge base for RAG, or structuring data for analytics dashboards, we ensure your data is accurate, complete, and in the right format. We also build automated pipelines so this is not a one-off exercise — your data stays clean and current as new records flow in.
Use Cases
What this looks like in practice
Training Data Preparation
Curate, clean, and label datasets for fine-tuning or training custom AI models. Handle annotation workflows, quality control, and dataset versioning.
Knowledge Base Construction
Structure your internal documents, wikis, and data into a clean knowledge base optimised for retrieval-augmented generation (RAG) systems.
Data Cleaning & Deduplication
Identify and resolve duplicates, inconsistencies, missing values, and formatting issues across your databases and data warehouses.
ETL Pipeline Development
Build automated extract-transform-load pipelines that continuously prepare incoming data for AI consumption without manual intervention.
Data Labelling & Annotation
Set up labelling workflows for text, images, or structured data. Combine human annotators with AI-assisted labelling for speed and accuracy.
