What I'm looking for

I seek data engineering or analytics roles with opportunities to build ETL pipelines, automate workflows, and contribute in international, growth-oriented teams.

I am a Data Engineer and Data Analyst with hands-on experience building ETL pipelines, automations, and chatbots using Python, SQL, Apache Airflow and n8n. I transitioned from a 19-year physiotherapy career into data, bringing strong analytical thinking, resilience, and a results-oriented mindset to technology projects.

I've implemented data environments and optimized SQL queries across MySQL, PostgreSQL and SQL Server, developed ETL processes in Python, and delivered customer and sales insights as a freelance automation developer. I am pursuing postgraduate studies in Data Science with focuses in statistics, financial mathematics, and machine learning, and actively seek international opportunities to grow in Data Engineering and Analytics roles.
