What I'm looking for

I'm looking to apply data analysis, dashboard development, and Python automation to practical business problems, especially roles involving structured datasets, KPI tracking, document-processing workflows, and opportunities to build efficient tools.

I've built Python automation tools at Dexterous Training Institute for bulk PDF certificate processing, file splitting and renaming, and recipient-name extraction into Excel. I upgraded the tool with a local AI model to handle unfamiliar certificate layouts.

I create structured Excel workflows for student records, attendance, results, and certificate documentation, helping improve repetitive document-handling processes.

At Construction Review Online, I analyzed views, clicks, and content trends to identify high-performing topics and inform editorial planning. I maintained tracking datasets in Excel and Google Sheets and produced more than 100 articles.

My Information Technology background supports my work across SQL, Power BI, Looker Studio, Excel, Python, OCR, dashboards, KPI tracking, and data cleaning.
