Data & Analytics Transformation Consulting

Stop manually consolidating your business data.

SDM helps growing businesses understand what fragmented data is costing them, design the right data foundation and build reliable management intelligence across finance, sales and operations.

Value Before Technology

Find the cost hiding inside your data.

Fragmented systems do more than slow reporting. They absorb productive hours, delay decisions and make valuable opportunities harder to see. SDM turns that hidden drag into a clear economic opportunity.

01Reporting effortHours × people × frequency × loaded cost
02Revenue opportunityMissed opportunities × frequency × estimated value
03Operational dragCurrent cost × addressable reduction
04Risk exposureProbability × financial impact
05Decision latencyThe cost of delayed or unavailable information
The SDM approach

Quantify the opportunity first. Recommend technology second.

Estimate Your Opportunity
The SDM Point of View

Business outcomes first. Architecture second.

We do not begin by asking which platform you should buy. We begin by understanding what the business is trying to achieve, where data is constraining it and what opportunity is worth pursuing.

SDM Data Value & Architecture Assessment

A structured diagnostic that identifies where your data environment is creating cost, risk and missed opportunity, then turns the findings into a practical transformation blueprint.

Typical investment From £2,500

Typically delivered in 1–2 weeks, with final scope depending on organizational complexity, systems, stakeholders and data sources.

The assessment does not obligate you to use SDM for implementation.

The Diagnosis

What's Holding Your Operations Back?

Pick your bottleneck. I will engineer the exact structural fix.

01

Drowning in manual spreadsheet extraction?

I deploy zero-maintenance Ingestion Pipelines (Fivetran, Airbyte, SSIS) to automatically pull data from your operational tools directly into the cloud. Eliminate the human bottleneck.

02

Messy, siloed legacy databases?

Stop overwriting historical states. I build highly scalable Data Warehouses & Lakehouses (Snowflake, Databricks, SQL Server) to establish a singular, cross-border source of truth.

03

Conflicting executive KPIs?

Eliminate departmental metric debates. I engineer governed dbt Models & Power BI Dashboards, ensuring Finance, Sales, and Marketing all report on the exact same numbers.

The Architecture Framework

How I Build Your Reporting Engine

Three phases. One compounding system. Every engagement starts with foundational stability and scales into advanced intelligence.

01. EXTRACTION & LOAD

The Pipeline

I securely connect your SaaS apps, CRMs, and on-premise databases, piping raw data directly into a unified cloud environment with zero data loss.

Fivetran SSIS Python
02. TRANSFORM & STORE

The Backbone

I untangle messy JSON and legacy tables, applying Kimball modeling via modular dbt code to create clean, tested star-schema data marts.

03. SERVE & VISUALIZE

The Multiplier

I deploy governed semantic models and real-time dashboards. The value of your data multiplies through automated daily refreshes and executive visibility.

Why Trust SDM?

Zero Fluff. Total Governance.

01. Outside IR35 & Compliant

Strict B2B Statement of Work (SOW) engagements. You secure high-level data architecture without the UK tax risks or overhead of full-time hires.

02. Direct Accountability

As an independent consultant, I do not bait-and-switch. The senior architect you speak to on the discovery call is the exact same engineer writing your SQL and DAX code.

03. Revenue-First Engineering

I do not build tech for tech's sake. From dbt models to API extractions, every line of logic I write is tied to an operational outcome your business can measure.

04. No Vendor Lock-In

You own the intellectual property. I provide full metric catalog documentation, inline Git repository comments, and structured handoffs to your internal teams.
