About

Portrait of Martin Kilombe
Martin KilombeIn data since 2021

Data Engineer & Analyst with 4+ years across finance, consumer behavior and operations. Currently Data Engineer & Lead Data Analyst at Cloud Intelligence: dashboards that lifted decision effectiveness by 40%, a real-time data-quality framework watching 100+ metrics, and local-LLM automated reporting.

Before that I built the plumbing itself: Python/SQL ETL moving 10M+ records a month at 99.5% uptime on PostgreSQL and Google Cloud. An actuarial-science foundation means the statistics underneath are as sound as the pipelines.
