What I'm looking for

I seek a data-focused role where I can apply SQL, Python and Power BI to improve operational KPIs, work in collaborative teams, and continue learning through structured data science projects and postgraduate study.

I am a chemical engineer transitioning into the data field, with hands-on experience in production and process engineering, KPI monitoring, and team leadership. I bring practical improvements—such as a 20% operational efficiency gain and reduced sample delivery times—combined with technical proficiency in SQL, Python, and Power BI.

I have supported large-scale plant shutdown planning, led a 57-person team for a successful turnaround, and contributed to product development and quality processes. I am pursuing postgraduate studies in Data Science to deepen my skills in data analytics and engineering and to deliver data-driven operational improvements.
