Methodology

THE SYSTEM.

01 — Discover
The Audit
I go in hard. No diplomatic sugarcoating — a raw technical assessment of your data landscape: where the debt is buried, what nobody trusts, and what will collapse under scale. You'll know the truth within days, not months.
02 — Design
The Blueprint
Architecture before code. We lock the single source of truth, define data flows, governance contracts, and product scope. No improvisation mid-build. The blueprint is signed before a single pipeline runs.
03 — Build
The Execution
We ship. Pipelines, semantic layers, dashboards — built to production standards, not demo standards. CI/CD, automated deployment, peer review. Delivery is measured in weeks, not quarters.
04 — Handoff
The Ownership
You own it. Fully. I train your team, write the governance playbooks, and document every decision — so the system survives without me and you never call me for the same problem twice.

Data Architecture
The Problem
Siloed systems (Keboola, Snowflake, ERP, legacy JDBC), no single source of truth, and data nobody trusts — killing decision speed at every level.
The Solution
Medallion architecture (Bronze / Silver / Gold) on Microsoft Fabric with OneLake, Fabric Lakehouses, Direct Lake mode, and governed semantic layers that scale.
Microsoft FabricMedallion ArchitectureOneLakeDirect LakeAzure SynapseSnowflake
BI Product Development
The Problem
Reports nobody opens, dashboards that mean different things to different teams, and KPIs that erode trust with every refresh cycle.
The Solution
Decision-first BI products built around user journeys — from executive scorecards to operational drill-throughs. Kimball-modelled, GxP-compliant where needed.
Power BIDAXPBIPPaginated ReportsTableauQlik SensePower Apps
Data Engineering
The Problem
Fragile manual pipelines, Excel consolidations, and data that arrives broken — leaving analysts firefighting instead of delivering insight.
The Solution
Automated ETL/ELT pipelines from source to semantic layer via Fabric Data Pipelines, Dataflows Gen2, ADF, and Notebooks — with CI/CD via Git and PBIP.
ADF / Data FactoryDataflows Gen2Notebooks / SparkdbtSQLPythonGit / CI-CD
Product Ownership & Delivery
The Problem
Data projects that run over budget, under-deliver, and lose stakeholder trust — because nobody is translating business needs into technical reality.
The Solution
Acting as the bridge between business and engineering — defining vision, managing backlog, running Agile ceremonies, and ensuring production-grade BI delivery.
Product StrategyAgile / ScrumJIRAConfluenceStakeholder MgmtOKRsUX Design
AI & MCP Integration
The Problem
Manual reporting cycles, analyst bottlenecks, and insights that arrive too late — reactive decisions instead of proactive intelligence.
The Solution
MCP Server integration with Power BI enabling AI-driven, context-aware data interactions and automated report generation. Copilot for Fabric + Azure OpenAI pipelines.
