About Me
Data Scientist delivering production-ready solutions with Python
Hi, I'm Waleed Hassan
I'm a Data Scientist and AI Engineer completed my Bachelor's in Computer Science (Specialization in Data Science )at the University of Engineering and Technology Mardan. If you need Power BI dashboards, AI Chatbots, or Data Engineering and ETL services, I build practical solutions that deliver measurable business impact.
With hands-on experience as a Data Analyst at Step Up Sol and Infinity Bits, I've developed expertise in Business Analysis, Analytical Skills, Databases, Microsoft Fabric, and Microsoft Power BI . I believe data science is only valuable when it drives real decisions and measurable outcomes.
I'm particularly passionate about Python-first development, machine learning, and creating compelling data visualizations. My work combines technical depth with business acumen, certified by IBM as a Data Analyst Professional with expertise in SQL, Python, and data analysis tools.
