Services / Data Quality, Analysis & Cleanup

Messy data in.
Clean answers out.

The unglamorous work everyone postpones — audits, deduplication, schema remediation, and SQL-heavy analysis — done offshore, documented, and delivered to Fortune 500 standards.

Data quality and cleanup is the work of making messy enterprise data trustworthy — auditing it, removing duplicates, fixing schema problems, and standardizing it — so downstream reports and migrations can be relied on. Thinklens delivers this offshore in a documented, reversible sequence: column-level audit and profiling (null rates, value domains, duplicates, orphans, and cross-system drift) ranked by business impact; deduplication with domain-tuned match rules and agreed survivorship logic, executed with full before/after lineage; schema remediation through staged migrations coordinated with downstream reports; and standardization with validation rules wired in at entry so the data doesn't decay. Senior, SQL-first analysts then run root-cause investigations, reconciliations, and ad-hoc or recurring reporting in Power BI, Tableau, or Spotfire on the cleaned data. Cleanup is scoped for what's next — SAP S/4HANA, Workday, or warehouse moves — and leaves behind the rules, gates, and monitoring that keep data clean.

Fix the data,
not just the symptom.

A wrong number in a dashboard is rarely a dashboard problem. We work backwards from the symptom to the source — then fix it where it lives, with an audit trail of every change.

Step 01

Audit & Profiling

Column-level profiling across the estate — null rates, value domains, duplicates, orphans, drift between systems — summarized in a findings report ranked by business impact, not row count.

Step 02

Deduplication & Survivorship

Match rules tuned to the domain (fuzzy on names, exact on tax IDs), agreed survivorship logic, and merge execution with full before/after lineage — reversible, never destructive.

Step 03

Schema Remediation

Misused fields, overloaded columns, and missing constraints corrected with staged migrations — coordinated with the downstream reports and integrations that depend on them.

Step 04

Standardization

Reference-data alignment, unit and format normalization, and validation rules wired in at entry — so the dataset that took weeks to clean doesn't decay back in a quarter.

Answers,
not just extracts.

Once the data is trustworthy, we put senior analysts on it — SQL-first, BI-fluent, and used to presenting to stakeholders who ask "why" twice.

Analysis

SQL-Heavy Investigation

Root-cause analysis, cohort and trend work, and reconciliation investigations directly against the warehouse — documented queries your team keeps after the engagement ends.

Reporting

Ad-hoc & Recurring Reports

One-off deep dives or scheduled reporting packs in Power BI, Tableau, or Spotfire — built on the cleaned data so the numbers agree with the systems of record.

Migration

Migration-Ready Datasets

Cleanup scoped for what's next — SAP S/4HANA moves, Workday rollouts, warehouse consolidation — so the new system goes live on data that's already been through quarantine.

Most data-quality projects fail by being framed as one-time cleanups. We leave behind the rules, gates, and monitoring that keep the data clean after we're gone.

Questions,
answered.

What does a data cleanup engagement involve?

Audit and profiling ranked by business impact, deduplication with domain-tuned match rules and survivorship logic, schema remediation via staged migrations, and standardization with validation rules wired in at entry.

Is your deduplication reversible?

Yes — merges run with full before/after lineage and agreed survivorship rules; the process is reversible, never destructive.

Can you prepare data for an SAP or Workday migration?

Yes — cleanup is scoped for what's next (SAP S/4HANA, Workday, or warehouse consolidation) so the new system goes live on data that has already been through quarantine.
