About me

I am a statistics graduate who likes turning raw numbers into something a decision-maker can read in a minute. I validate data carefully, build clear Power BI reports with DAX, and automate repetitive work with Google Apps Script. I explain findings in plain language, so the people who act on them understand them.

HR Attrition Analysis — Executive Summary & Findings

An executive synthesis of insights from analyzing IBM's 1,470-employee workforce dataset. While you can interact with the live report above, this section outlines the critical turnover drivers, visual evidence across report pages, and high-impact retention recommendations for HR leadership.

First-Year Attrition

First-year employees leave at over twice the rate

57.1% of employees who quit do so within their first year — compared to just 11.6% for those who have been at the company for over 10 years. Onboarding quality and early role clarity are the clearest levers to pull.

57.1% attrition in year 1
Commute Impact

Longer commutes consistently drive higher turnover

Attrition rises steadily with commute distance. Employees travelling over 20 km daily exit at significantly higher rates than those within 5 km. Hybrid or flexible location policies are the most immediate countermeasure.

20+ km highest-risk distance band
Age Demographics

Young talent is the most at-risk group

The 18–25 age band records the highest attrition at 55.7%, falling with each successive band. Without visible career progression paths and salary parity, early-career hires disengage and exit quickly.

55.7% attrition, age 18–25
Strategic Takeaway

Three retention levers with the highest ROI

1. Structured 30/60/90-day check-ins to identify disengagement before the 12-month cliff.

2. Hybrid or remote options for employees commuting 15+ km, where flexibility directly lowers exit risk.

3. Junior career pathways — defined promotion timelines and mentorship for the 18–25 cohort.

Invoicing, inventory and sales automation

A Google Apps Script system that generates invoices, tracks stock and produces sales reports, so none of it is typed by hand.

Google Apps ScriptGoogle SheetsWorkflow automation
  • Creates invoices automatically from sales entries.
  • Updates inventory as items sell, and rolls sales into reports.
  • Handles quantity corrections after an invoice is already generated, a case most simple systems miss.
  • For clients, I map the current workflow, find the bottleneck, build the automation and hand over a written implementation guide.
