Data platform modernization
Move the enterprise off legacy data debt — without pausing the business

Hyperscalers & platforms we engineer on
Services
Built by engineers, scoped for engineering leaders
No 80-slide transformation decks. Small senior teams, working software in weeks, and an architecture your platform group can defend in review.
Lakehouse architecture
Target-state design on Azure and Databricks: medallion layers, Unity Catalog governance, cost guardrails and a reference implementation your teams can extend.
Legacy migration engineering
Teradata, Informatica, SSIS, Hadoop and Synapse estates moved to Delta Lake with automated inventory, parity testing and wave-based cutover.
Revenue & commercial analytics
Gross-to-net revenue models, trade spend, subscription recognition and cohort economics — one definition consumed by finance, growth and product.
Data & ML engineering
Streaming and batch pipelines, dbt modelling, feature stores and MLflow-tracked models running in production, not in notebooks.
Governance & platform ops
Access models, lineage, PII handling, SOX-ready audit trails and FinOps reporting embedded from day one rather than bolted on.
Platform enablement
Golden paths, CI/CD with Terraform and Asset Bundles, and hands-on enablement so your engineers own the platform after we leave.

How we work
Five stages, each with a decision gate
Every engagement is time-boxed and reversible. You can stop after the diagnostic and keep the plan.
Discovery
W1–W2
Architecture & landing zone
W2–W5
Wave 1 migration
W5–W12
Parallel run & sign-off
W10–W14
Every lane ends in a decision gate — stop, extend or scale.
- 01
Diagnose
Two weeks. Estate inventory, cost baseline, data-quality hotspots and the reporting flows that actually run the business.
- 02
Architect
Target lakehouse blueprint, governance model, migration waves and a business case with explicit run-cost projections.
- 03
Build in waves
Thin vertical slices per domain: ingest, model, validate, expose. Parity harness proves the new number matches the old one.
- 04
Cut over
Dual-run, sign-off gates, decommission plan. No reporting blackout, no big-bang weekend.
- 05
Hand over
Runbooks, CI/CD, on-call model and enablement sessions. Your team runs it; we stay available for the hard weeks.
Case studies
Platforms we have delivered
Packaged snacks · LATAM and Middle East & South Africa retail
Revenue analytics across 12 retail chains, refreshed hourly
Replaced a nightly Excel-and-SSIS revenue pack with a Databricks lakehouse serving trade-spend-adjusted net revenue to 400+ commercial users across LATAM and Middle East & South Africa.

Consumer app · San Francisco
Audience business review analytics
Legacy BI could not deliver near real-time app usage insight; every analysis was a manual data pull.
Fully automated daily audience and revenue review
Global BPO / ITeS · France
Operational insights for 400 contact centres
No unified view of agent and process performance across two South Asian contact centres.
2% CSAT improvement and 5% reduction in shrinkage
