What I'm looking for

I'm looking for data engineering or data platform work where I can own architecture, reliability, cost optimisation, governance, and production operations. I'm available immediately and open to on-site, hybrid, or remote roles, including relocation to Switzerland.

I've built and operated cloud data platforms for international consulting clients, including a US communications group where I re-engineered a 10 GB daily allocation pipeline, cutting BigQuery runtime from four hours to 20 minutes and monthly cost from about USD 1,000 to USD 10.

Across AWS, GCP, Snowflake, dbt, Airflow, and Python, I've owned production platforms for marketing, e-commerce, EdTech, financial software, and AI. My work has included 15 Snowflake pipelines for 50 users, campaign ROI attribution across six countries, and database and backend services supporting 10,000 students.

Previously at Packlink, I delivered financial KPI models and dashboards for around 25 analysts, investigated high-impact billing data issues, helped hire three engineers, and carried full on-call and incident-response responsibility.
