About

I have over 8 years of work experience across banking, financial services, customer operations and HR analytics, and my background is HR. I hold an MSc in Human Resource Management and I'm an Associate Member of the CIPD and a Master HR Analytics Professional (MHRAP). The analytics grew out of that background.

I build the reporting and models that answer the questions HR leaders get asked: who is leaving and what it costs, where hiring slows down, and how much headcount a plan needs. I work in SQL and Excel to get the data right, and use Power BI to put it in front of the people making the decision.

  • Workforce planning and headcount forecasting
  • Attrition, retention and cost-of-turnover analysis
  • Recruitment funnel and time-to-hire analysis
  • HR reporting automation in Power BI
  • HRIS data cleaning, validation and governance

Case studies

Explore four Power BI projects. Each report covers the business question, data, analysis and recommendations.

Problem

Response times were slipping, and it wasn't clear where in the workflow the delays were.

Data

Interaction-level logs: response time, resolution time, CSAT score, contact reason and channel.

Analysis

  • Cleaned the logs in Excel and tagged each ticket by contact reason and channel.
  • Compared response and resolution times by contact reason to find where delays built up.
  • Built a Power BI dashboard tracking CSAT, average handle time (AHT) and first-contact resolution (FCR) against SLA targets.

Reducing First-Year Attrition

A worked example of an early-tenure attrition analysis, built on a fictional company.

  • Power BI
  • Python
  • Cohort analysis
View projectHide project

What this is

A worked example of method. The company, data and figures are fictional and do not describe any real organisation or engagement.

Approach

  • Monthly hiring cohorts to find when in the first year leavers were most likely to go.
  • Exit-interview themes coded by category.
  • A simple risk flag using tenure, pay position and manager signals.

Recommendations modelled

  • Structured 30/60/90-day onboarding check-ins.
  • Coaching for managers of new starters.
  • Transparent levelling and pay bands.
