Portfolio Builder / Product-minded Engineer
Personal Projects · Copenhagen
Built job-facing portfolio systems around support automation, workflow systems, data-quality checks, and iOS product implementation. The emphasis is not feature volume, but clear problem framing, evidence, boundaries, and explainable implementation choices.
Built a support/operations desk with queues, evidence packages, draft replies, approval gates, feedback memory, and audit replay. Demonstrates workflow automation with human review, traceability, and evaluation thinking.
Built a small Python data-checking demo for logistics records: missing fields, duplicates, stale records, invalid values, JSON run output, and an HTML report for review.
Built and structured SwiftUI weather-journal features across weather data, widget/shared settings, radar/wind features, moon illumination, and fallback behavior.
MSc Thesis / Optimization Research
