Data You Can Trust.
Testing That Delivers.
Senior data testing expertise for banking and financial services. 14+ years validating complex data pipelines — from Azure Databricks to Power BI.
Senior expertise. No juniors.
X36 is a boutique data testing and QA consultancy run by a Senior Data Testing Consultant with over 14 years of hands-on experience in banking, finance, and insurance. We work directly with your team — no account managers, no junior handoffs — to validate your data pipelines, build quality frameworks, and make sure the numbers your business relies on are actually right. We combine deep domain expertise with modern tooling — leveraging AI to accelerate test design, spot anomalies faster, and catch data quality issues before they hit production. From automated test suites built into your CI/CD pipeline to AI-assisted validation across Databricks, dbt, and ADF workflows, we help you move faster without trading away accuracy.
Every engagement is led by a senior consultant with deep domain knowledge in financial services data.
What we do.
Data Quality & Testing Strategy
End-to-end data quality frameworks tailored to your environment. We define testing standards, build validation rules, and establish the processes that keep your data trustworthy at scale.
Databricks & dbt Pipeline Validation
Hands-on testing of Azure Databricks and dbt pipelines — staging, intermediate, and mart layers. We validate transformations, test data contracts, and catch issues before they reach production.
ETL & ADF Testing
Comprehensive testing of Azure Data Factory pipelines and ETL processes. Source-to-target validation, transformation logic testing, and reconciliation across ADLS and Cosmos DB.
Test Automation & AI-Augmented QA
Python-based test automation frameworks and AI-augmented testing workflows that reduce manual effort and increase coverage. Built for modern data stacks, not legacy tooling.
Power BI & Reporting Validation
End-to-end validation of Power BI reports and dashboards — from source data through to visual output. We verify calculations, DAX logic, and ensure reports reflect reality.
The difference is in the detail.
Deep banking domain knowledge
14+ years in banking, finance, and insurance means we understand the regulatory context, the data models, and the stakes — not just the tooling.
Senior-only delivery
You get the senior consultant, every time. No bait-and-switch to junior staff. The person you brief is the person who does the work.
Modern data stack expertise
We work natively in Azure Databricks, dbt, ADF, and Python — the tools your team is already using, not legacy testing frameworks bolted on.
Embedded, not external
We work as part of your team, not as an outside auditor. Faster feedback loops, better outcomes, and knowledge that stays with your organisation.
Tools we work in natively.
