Data architecture audit

Diagnose the DWH and the data platform: workarounds, risks, growth stalls.

I come into a company where the DWH or platform is already running, but something is off. Slow reports, a growing engineering backlog, regulator questions, migration talk. I look at the architecture with the eyes of someone who has built it inside several banks.

I walk the layers: raw, core, mart. Ingestion, orchestration, governance, metrics. I record gaps between what the documentation claims and what actually runs. I put a price and a timeline on the technical debt.

The output is a report: AS-IS diagrams, a prioritized issue list, and three 12–24 month scenarios. Each scenario carries a cost and risk estimate. The decision stays with you.

For whom
CTOs, Heads of Data, VPs of Engineering in banks and fintech with an existing DWH they don't want to rewrite from scratch.
We solve
Regulator reports get assembled by hand and slip deadlines. Data engineers complain about legacy. Migration is on the table with no clear target. Prior consultants left a deck, not a plan.
Deliverables
A 30–50 page report: AS-IS architecture and data flow diagrams, a prioritized issue list, three 12–24 month development scenarios with time and budget estimates, and an executive summary for the CTO and CFO.
Format
Remote, plus 3–5 days on-site for team interviews.
Duration
3–4 weeks.
