Dear Prospective Employer or Client,

If you’re looking for a data analytics professional who delivers measurable business impact rather than just technical outputs, I’d welcome the opportunity to discuss how my expertise could benefit your organisation.

What I Bring to the Table

Over the past 10 years, I’ve built my career on a simple principle: analytics exists to drive business outcomes, not just produce reports. Whether implementing GDPR-compliant tracking architectures for enterprise clients, building Marketing Mix Models that identify £200K+ optimisation opportunities, or engineering modern data stacks that eliminate 85% of manual reporting, my focus remains constant—translating complex data challenges into actionable business improvements.

Currently serving as Lead Data Analyst & Optimisation Strategist at Inviqa UK (Havas Group), I lead analytics strategy for clients. My work spans the complete analytics lifecycle: from server-side tracking implementation and consent management frameworks to advanced Bayesian modelling and executive dashboard development. This comprehensive capability means I can diagnose technical problems, engineer robust solutions, and communicate findings to both technical and non-technical stakeholders.

The Value I Deliver

My track record speaks to consistent, measurable outcomes:

  • Marketing Efficiency: 25-35% improvements through Marketing Mix Modelling and attribution analysis
  • Cost Optimisation: £150K-£200K+ annual opportunities identified across client portfolios
  • Infrastructure Modernisation: 85% reduction in manual reporting through analytics engineering
  • Risk Mitigation: £400K+ regulatory exposure eliminated per GDPR implementation
  • Return on Investment: 300-600% ROI across MMM, analytics engineering, and conversion optimisation projects

These aren’t theoretical capabilities—they’re results delivered for real businesses facing real challenges.

My Technical Approach

I specialise in advanced frameworks that most organisations struggle to implement internally:

  • Marketing Mix Modelling: PyMC-Marketing (Bayesian), Meta’s Robyn, Google’s Meridian
  • Analytics Engineering: dbt, SQL Mesh, BigQuery, modern data stack architecture
  • Privacy & Compliance: Server-side tracking, Google Consent Mode v2, OneTrust, Cookiebot
  • Statistical Modelling: Bayesian inference, econometric modeling, predictive analytics

But technical capability alone isn’t enough. What differentiates my work is the ability to bridge the gap between technical execution and business strategy—ensuring that sophisticated analytics infrastructure actually drives decision-making rather than sitting unused.

Current Focus & Availability

I’m completing my MSc in Data Science at UWE Bristol (specialising in machine learning and predictive analytics) while maintaining my role at Inviqa UK. I also operate WebIQ Analytics as a freelance consultancy for select clients requiring bespoke Marketing Mix Modelling, analytics engineering, or conversion optimisation solutions.

I’m open to discussing:

  • Permanent roles where I can lead analytics strategy and infrastructure development
  • Consulting engagements for high-impact analytics projects (MMM, analytics engineering, GDPR compliance)
  • Collaborative opportunities where my expertise complements your existing capabilities

 

Let’s Discuss Your Challenges

Whether you’re struggling with attribution gaps, drowning in manual reporting, facing GDPR compliance challenges, or simply not extracting the value you should from your marketing investment, I’d be happy to explore how my experience might help.

The best way to assess fit is through conversation. You can reach me at hello@terrymanu.com or +44(0) 7708119963, or connect with me on LinkedIn.

I look forward to learning about your analytics challenges and discussing how we might work together.

Best regards,
