Senior developer on an enterprise lakehouse migration from Snowflake into Dremio on Apache Iceberg — metadata-driven Ab Initio pipelines across staging, raw and extended layers.
Ab Initio specialist with 21 years delivering enterprise ETL and data-governance platforms for Europe's largest banks, payment networks and regulated enterprises — on-site in 8 countries, across GCP, AWS, Azure and StackIT.
Enterprises inherit their data estates. We rebuild them from the source — migrated without loss, governed without gaps, and measured until provable.

Five disciplines, one standard: every pipeline versioned, every field traceable, every cutover rehearsed.
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%.
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.
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.
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.
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.
Technical lead in a team of five; rationalised Agile Ab Initio practice, ingesting retail data into a Teradata EDW.
Metadata import and technical lineage via Metadata Hub; DQ rules in Collibra; DQ metrics via Data Quality Assessment.
Payments matching engine parsing CAMT.053/MT940 statements, reconciled against transactions and settlement data.
Real-time risk-distribution engine on Continuous Flows and the Web Services Framework; SWIFT payments engine (MT103/910/942).
Brand-migration plans with Express>It rule sets; Oracle-to-Oracle telecom migration delivered in 10-day sprints.
Ab Initio on Hadoop with Co>Relate matching and Query>It/Express>It profiling; SWIFT ISO 20022 modelling.
Rebuilt a Net Asset Value calendar module for an asset-management division.
Teradata EDW and SAP GL interfaces for Enterprise Provisions; invoice-discounting across Teradata, SAP and z/OS.
24×7 production support of a tier-one bank's cash-management platform, to aggressive SLAs.
Core banking platform replacement, delivered across multiple time zones and daily batch cycles.
Data-integration projects for a global payments and financial-services client; hands-on with Ab Initio GDE, Data Profiler and EME.
Begin at the source. Architecture is derived from first principles — data shapes, contracts, and failure modes — never inherited from the incumbent vendor.
Every field accounted for. Lineage, fixity, and audit evidence travel with the data — from first ingestion to final consumption, human or machine.
Migrations are measured in basis points of loss — target zero. Cutovers are rehearsed, reversible, and deliberately uneventful.
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.
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.
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!
From day 1 Sandeep showed his professionalism to get to grips with the setup and provided the customer with an instant assurance that the issues they were experiencing were under control. A well-rounded IT professional with excellent customer-facing skills.
Sandeep is a very direct and open-minded conversational partner who helps to find the most efficient solution for the task. His experience and drive have played a crucial role in our design and implementation. I would really like to work with him again!
In addition to his technical skills, Sandeep is an effective communicator with the ability to collaborate to provide the optimal solution. I would highly recommend him as an Ab Initio expert, problem solver and team player.
A short conversation is enough to scope most engagements. You get senior attention from the first call — because that is the only kind we have.
