Data you can trace, name, and answer for.

I own data for a consumer banking line of business: deciding which sources can be trusted, fixing the ones that can't, and putting a name to every answer. Eight years across warehouses, catalogs, and now a bank's operations.

Experience

Four roles, one arc: from running warehouses to governing what they hold.

August 2026 – present

Data Owner

Mphasis · deployed to a global bank's consumer operations division, Hyderabad

Data Owner for a consumer banking line of business, accountable for an assigned subset of its data domains and for the accuracy, consistency and completeness of what they hold. The role sits between business stakeholders, data engineering, architecture and governance, and underneath it all is dataset-level judgment: which source answers which question, by grain, refresh and certification status.

  • Defining and enforcing governance standards and policies for owned domains, and keeping them aligned with the enterprise framework.
  • Analysing data in SQL to surface quality issues, tracing them to root cause, and leading remediation through to corrective action.
  • Ensuring data readiness, validation and governance across the cloud migration lifecycle.
  • Monitoring data quality metrics and reporting on ownership, quality and governance through dashboards and documentation.
  • Contributing to lineage, metadata management and master data management initiatives.
October 2022 – May 2026

Lead EDC Developer

Tata Consultancy Services · pan-European insurance group, GDPR governance program

Led Informatica Enterprise Data Catalog delivery across ten countries: catalog administration, resource and connection design, remote-agent scanning across regions, profiling, and data-domain discovery, with curated metadata flowing into Collibra for enterprise stewardship.

  • Built custom mapplets with regex-based data-domain rules that classified sensitive columns automatically for GDPR reporting.
  • Reworked the scanning strategy for the heaviest databases, cutting scan time from 6–8 hours to 1–2.
  • Onboarded Azure SQL Data Warehouse as a cloud resource in EDC to meet EU residency requirements, an out-of-scope request delivered on priority.
  • Ran the EDC-to-Collibra REST integration as power user, from metadata pushes to debugging the early issues.
  • Stayed on as the team wound down from six to one, running the catalog end to end until project sunset: development, deployment, support, and every stakeholder conversation. The hardest stretch of the program, and the one that taught me to operate rather than contribute.
  • After the program wound down, moved to a manufacturing client as L2 support and migration liaison for their OBIEE reporting estate, through to leaving TCS in May 2026.

Senior System Analyst, Operations Lead

Cognizant · vehicle manufacturer, Teradata data warehouse

Led a 12–15 member operations team covering system health, batch execution, database administration, and deployments for a Teradata warehouse fed by Informatica PowerCenter.

  • Raised batch SLA from 70% to 98% within three months through parameter optimisation, query tuning, and process fixes.
  • Led three migrations: two PowerCenter upgrades (9.x to 10.x) and an on-premise move to Teradata Cloud and Informatica Cloud, completed in three days against a five-day plan.
  • Introduced ServiceNow alert automation that reduced SLA misses and escalations; represented the team in daily Scrum and executed critical batch releases personally.
July 2018 – June 2021

Programmer Analyst Trainee, then System Analyst

Cognizant · UK banking institution

The first project, and still the foundation. Application and production support for banking systems on Unix and Oracle: batch jobs, server maintenance, uptime monitoring, incident troubleshooting, and user provisioning across Ab Initio and PowerCenter.

  • Became the team's cross-functional resource across all three project domains, deployed by management on high-priority issues.
  • Resolved a major escalation by bringing every stakeholder into one thread and clearing a mismatch between what users expected and what they had requested.

Approach

Three habits that have held up across every estate.

Lineage before dashboards

A report nobody can trace is an opinion with a chart. I start from where the data enters and work forward, so every number downstream has a path back.

Owners, not custodians

Governance fails quietly when everyone is responsible and no one is accountable. I push for a named owner on every critical element, with the authority to say no.

State the edge of the map

I bound what I know precisely and name what I don't. It has cost me nothing in interviews and saved me plenty in delivery.

Capabilities

What I can be handed, end to end.

Catalog administration

Informatica EDC end to end: catalog, analyst, model repository, scanning and profiling services; resource design, permissions, and remote agents across regions.

Lineage architecture

Column-level lineage through ETL layers, and defensible manual lineage for legacy platforms that no scanner reads.

Governance frameworks

Critical data element identification, business glossary ownership, data-domain rules and curation workflows, GDPR and data-residency design across jurisdictions.

Platforms

Oracle, SQL Server, Teradata, PostgreSQL, SAP HANA, DB2 for i, Azure ADLS and Synapse. Collibra as power user and REST integrator. PowerCenter, IDQ, SQL.

The formal side, kept short.
