Every engagement is different. Here's a cross-section of the data challenges we\'ve solved — across industries, dataset sizes, and business types.
A microfinance institution operating across 5 branches had accumulated 3+ years of loan records in separate Excel files — each with different column names, date formats and reference number conventions. Before a regulatory audit, they needed a single, clean, unified dataset.
An NGO running health programmes across 3 counties was migrating to a new EMR system. Their patient records existed in 3 different legacy databases, each built at different times with no shared schema. Merging them required deduplication across systems with no common unique identifier.
A retail chain operating across 8 African markets had a CRM with 200,000+ customer records — accumulated over 6 years with no cleaning. The records had duplicate contacts, inconsistent phone formats across 8 country codes, malformed emails, and blank mandatory fields.
An agri-tech startup needed to prepare soil composition and crop yield datasets for machine learning model training. Raw data from field sensors had noise, outliers, missing readings and unit inconsistencies that were degrading model performance.
A 600-person company was migrating from a 10-year-old on-premise HRIS to a modern cloud platform. Employee records had grown inconsistent over a decade of manual entry — department names varied, job titles were unstandarisable, and contract types used 11 different labels.
A hospitality group managing 12 properties needed to reconcile inventory data ahead of a group-wide ERP rollout. Each property had its own spreadsheet — 12 different product code formats, inconsistent supplier names and no unified category taxonomy.
Before Chui, our CRM was a nightmare — 50,000 records with thousands of duplicates. They cleaned it in under a week and our sales team finally trusts what they're working with. We saw a direct improvement in outreach conversion rates.
The team was incredibly thorough. They caught errors our internal staff had missed for months. Our financial reports are now accurate and we sailed through our regulatory audit. Worth every shilling.
Professional, fast and communicative throughout. They didn't just clean our data — they explained exactly what was wrong and how to prevent it recurring. That education piece alone was invaluable.
