About Saifullah Khan

I am a data-oriented professional with nearly two years of experience at Tech Mahindra, working as a Research Associate in a data-intensive role involving real-world GIS and location-based datasets.My work has involved on-site data collection and verification, followed by cleaning, validation, analysis, and structured reporting of large datasets. Over the last two years, I have consistently worked on data quality checks, identifying patterns and inconsistencies, and producing structured reports and insights to support operational and decision-making needs.I have hands-on experience working with messy, real-world data — understanding it at the source, structuring it, analyzing it, and converting it into reliable, usable information for teams and stakeholders. This experience has shaped my analytical approach and is what I now formally bring into Data Analyst roles.What I work with:Data cleaning, validation, and analysisExploratory data analysis and trend identificationStructured reporting and dashboardsWorking with large, real-world datasetsTools & skills:SQL | Python (Pandas, NumPy)| Excel (Advanced)| Power BI | Data Analysis | Data Cleaning | Data Validation | Exploratory Data Analysis | Reporting & DashboardsI am open to Data Analyst and analytics-focused opportunities where I can contribute through data-driven problem solving and insight generation.
