Introduction
I’m a Data Analyst with 5+ years of experience transforming complex data into actionable insights, with a strong track record in financial reporting, performance analysis, and cost optimization for high-profile clients across industries. I've had the privilege of working with global leaders such as KPMG, PwC, and Jumia, where I designed and implemented data-driven solutions that improved decision-making and boosted operational efficiency. My technical toolkit includes Python, R, SQL, and Power BI, along with a solid foundation in machine learning and business intelligence. Currently pursuing a Computer Science Engineering degree with a focus on Data Science, I’m deeply passionate about AI, advanced analytics, and the power of data to drive business innovation. Fluent in French, Arabic, and English, I bring a multicultural perspective, strengthened by international experience including a professional exchange at PwC Paris. Whether it’s building predictive models, automating workflows, or uncovering trends hidden in data, I thrive in complex environments and love turning data into impact. Let’s connect if you’re looking for someone who combines technical expertise with business acumen to unlock real value from data. #dataanalyst #datascientist #AIengineer #opentowork
