Data Cleaning & Preparation
Reliable tables before expensive modeling
Documented rules, regression tests on samples, and lineage you can audit.
Dirty data silently multiplies cost in BI and ML. We profile sources, codify cleaning rules, and version transforms so teams know what changed and why.
What we deliver
- Profiling: distributions, outliers, and cross-field integrity checks.
- Standardization: phone, email, pincode, GSTIN patterns where applicable.
- Deduping: fuzzy keys with human-in-the-loop thresholds when needed.
- Pipelines: idempotent jobs with checkpoints and replay.
- Documentation: data contracts and SLAs for freshness.
Testable transforms
Unit checks on edge cases before production loads.
Operational clarity
Alerts when upstream schemas drift.
Transparent delivery
Weekly demos, shared backlog, and release notes you can forward to stakeholders.
Security hygiene
