Tata Consultancy Services’s Data Engineering & Analytics vs. ours

Tata Consultancy Services's approach to Data Engineering & Analytics reflects their broader delivery model: large teams, long timelines, and a scope that expands with the engagement rather than resolving it. Staff augmentation model at scale — body-shopping dressed as transformation

Data Engineering & Analytics requires a specific kind of engineering precision that generalist delivery models do not produce. The capabilities required — Compliance-native data pipeline architecture, Data residency enforcement across cloud regions, Chain-of-custody logging for every transformation — are not skills that scale with headcount. They require engineers who have delivered these systems in production environments.

Our Data Engineering & Analytics practice deploys teams with production experience in the specific capabilities this service requires. Data engineering in regulated industries is not a standard ETL problem. Every pipeline we build has compliance built into the architecture: data residency rules enforced at the infrastructure level, retention policies automated rather than manual, and transformation logs that serve as audit evidence. ProofGrid monitors every data API endpoint for compliance violations continuously.

Fixed-price delivery with defined milestones. The first milestone is always a working system component — not a document. The engagement closes with full IP transfer: source code, documentation, and the operational capability for your team to run the system independently.
