I’m sitting on a data set that tops 100 million rows and I need clear, defensible insights pulled from it. At its heart, this is a data-analysis job—the sole objective is to identify the most meaningful trends hidden inside the numbers so I can steer business decisions with confidence. What I’ll hand over • Full raw data dump (structured, ready for import). • Any brief contextual notes you need to understand the fields. What I expect back • A reproducible workflow (Python, SQL, R, or Spark—whatever scales for you). • Cleaned and well-documented code notebooks/scripts. • Concise visualisations plus a plain-language summary that highlights the key patterns, shifts, and outliers you uncover. Acceptance criteria • Your process runs end-to-end on my machine or cloud environment without errors. • Findings are backed by clear charts or tables and an explanation I can present to non-technical stakeholders. • Delivery is on time and complete—raw code, final report, and any intermediate files. If tackling large-scale data excites you and uncovering trends is your specialty, let’s talk.
