Arjun Kumar

Data Analyst

I'm a detail-oriented Data Analyst with close to two years of experience turning raw, messy data into clear, actionable insight. My day-to-day lives at the intersection of SQL, Python, and dashboards — cleaning datasets, spotting patterns, and building reports that people actually use to make decisions.

I currently work as a Database Developer at NRT Consultancy Services, where I write and optimize SQL queries to manage large-scale student and examination datasets, clean and validate records to resolve discrepancies, and analyze subject-wise performance to help automate results processing. Before this, I built a strong foundation in Oracle SQL, PL/SQL, and data analysis through hands-on projects and certifications.

Outside of client work, I like exploring datasets on my own — recent projects include a sales performance analysis using Python and Power BI, and an employee management system built entirely on Oracle SQL and PL/SQL. I'm based in Patna, Bihar, and always open to interesting data problems.
