I am a data analyst with a strong foundation in turning complex datasets into actionable insights. With a background in Computer Science and professional training through the CareerFoundry Data Analytics Program, I specialize in using data to support strategic decision-making and uncover business opportunities.
My technical skill set includes SQL, Python (Pandas, NumPy, Matplotlib), Power BI, Tableau, and advanced Excel functions such as pivot tables, lookups, and dashboard creation. I have hands-on experience working with relational databases, writing optimized queries to extract and manipulate large volumes of data, and cleaning and preparing data for analysis.
One of my core strengths is creating clear, insightful dashboards and visual reports that make data understandable and useful for stakeholders. In past projects, I’ve developed end-to-end solutions—from collecting raw data to cleaning, analyzing, and presenting the final output. For example, I conducted a full market analysis of Airbnb listings in Amsterdam using Excel and Tableau, identifying pricing trends and booking behaviors. In another project, I analyzed customer rental patterns for a fictional video rental company using SQL and Python, helping to optimize inventory and marketing strategies.
I’m experienced in using data to identify inefficiencies, track KPIs, and support business improvements. I’ve worked with process mining techniques to uncover bottlenecks in workflows and understand how systems are used in real time. I’m also familiar with working in enterprise environments using SAP ERP systems (especially Production Planning and Materials Management modules), giving me context on how data flows in large organizations.
What sets me apart is my attention to detail, curiosity, and ability to explain complex findings in a clear, non-technical way. I enjoy collaborating with teams to solve real-world problems through data and always approach new challenges with a mindset of learning and improvement.
Whether you need support in cleaning and analyzing your datasets, building dashboards, or performing ad-hoc reporting, I bring both the technical expertise and business understanding to help move your project forward. I am committed to delivering work that is not only accurate but also meaningful and easy to act on.
Let’s connect and bring clarity to your data—so you can focus on what matters most: making informed decisions that drive results.
