THE PREMISE

Enterprises inherit their data estates. We rebuild them from the source — migrated without loss, governed without gaps, and measured until provable.

01 — CAPABILITIES

What we practise

Five disciplines, one standard: every pipeline versioned, every field traceable, every cutover rehearsed.

/ 01

Ab Initio Migration & Delivery

End-to-end delivery on the Ab Initio stack — and disciplined exits from it. Legacy ETL re-platformed to lakehouse architectures with CDC-driven continuity and zero-loss cutover. Recent work: a Snowflake-to-Dremio/Iceberg migration cutting new-table onboarding by roughly 80%.

/ 02

Data Governance & Quality

Governance that survives audit: quality rules with owners and thresholds, PII controls, records & unstructured-data governance, and access models built on RBAC/ABAC. One programme alone: 1,300+ data-quality rules deployed across a tier-one European bank.

DQ RULES PII RBAC / ABAC PROVENANCE FIXITY
/ 03

Metadata, Lineage & AI-Ready Data

Field-level lineage from source to consumption. Metadata models that make estates discoverable — by analysts, by auditors, and now by machines. Including a 40-field AI-ready metadata model, validated against 100+ real artefacts.

Cloud Data Platforms

Warehouse and lakehouse migration across four clouds — T-SQL to BigQuery, SAS to Hadoop, Teradata to Iceberg — dimensionally modelled, SCD-correct to the field. One migration alone moved 100+ billion rows onto BigQuery.

Technical Leadership & Continuous Delivery

Agile technical leadership embedded in your teams — CI/CD for data on Azure DevOps, real-time and continuous flows, and standards that outlast the engagement.

03 — PRINCIPLES

How we decide

01

Ab initio

Begin at the source. Architecture is derived from first principles — data shapes, contracts, and failure modes — never inherited from the incumbent vendor.

02

Provenance

Every field accounted for. Lineage, fixity, and audit evidence travel with the data — from first ingestion to final consumption, human or machine.

03

Continuity

Migrations are measured in basis points of loss — target zero. Cutovers are rehearsed, reversible, and deliberately uneventful.

04 — TESTIMONIALS

What clients say

I strongly recommend him for his ability to deliver end-to-end solutions on his own with the highest internal client satisfaction. Sandeep not only prepared data quality measurement solutions, but also trained more than 10 data stewards to be able to deliver data quality measurement solutions in Ab Initio themselves.
PETER J
SENIOR MANAGEMENT CONSULTANT · HUNGARY
Sandeep proved to be an efficient hands-on expert of Ab Initio, motivated and nice to work with. I strongly recommend Sandeep for Ab Initio implementations, metadata and data quality management — and as a nice person to work (and relax) with.
PIERRE D
CHIEF DATA OFFICER · BELGIUM
Fruitful conversations, discussions and development trials led to what is for sure a very good product in the end. Straight-up kind of guy who doesn't beat around the bush. Would really like to work with him again!
MICHIEL W
