Werkervaring

NGOs

Data Engineer, creation of star-schema database

NGOs • Freelance

Oct 2026 - Oct 2026 • 0 mos

Built a Python pipeline that extracts data from project reports (PDF, scans, Word, Excel) with an LLM and stores it in a structured Excel database. Designed the data model to answer any KPI question. Every value is traced to its source, and missing data is never counted as zero, so totals are reported as a proven minimum with a coverage rate. Added automatic checks and an expert review step to catch errors, and handed over the tool with documentation.

MassChallenge

Data analyst, clear view of Startup applications

MassChallenge • Freelance

Sep 2026 - Oct 2026 • 1 mo

Every year, the accelerator collects a huge amount of information on the startups that apply, and every hour spent making sense of it is an hour less spent with founders. Our answer came in three parts: a machine learning model to structure their data, a clear view of where their team can save time in their daily work, and practical tips to collect better data from day one. Because a model is only as good as the data it learns from.
