Nadish Rafi

I’m a results-driven Data Analyst with hands-on experience in data cleaning, transformation, visualization, and reporting. I turn structured datasets into actionable insights by identifying trends, patterns, and performance gaps.

During my Data Analytics Internship at Techolas Technologies, I analyzed business datasets using Python, SQL, and Excel to generate insights that supported management decisions. I clean, validate, and transform raw data to improve accuracy and reporting quality, and I develop interactive dashboards in Power BI and Tableau for KPI tracking and executive reporting.

I’ve delivered reporting automation through automated MIS reports, reducing manual effort and improving efficiency. I also perform statistical analysis to uncover operational bottlenecks, collaborate with stakeholders to understand reporting needs, and optimize data processes to increase visibility.

My projects reflect the same focus on clarity and decision support—building an Airline Operations Analytics Dashboard (Power BI), a Nike Sales Analysis Dashboard (Microsoft Excel), and an English Premier League Performance Dashboard (Tableau). With a strong foundation in statistics and business intelligence from my BCA, plus Google analytics-focused certifications, I bring attention to detail and strong communication to every analysis.
