πŸ‘‹ Hello, I'm Samuel Ojetunde

πŸš€ Aspiring Data Engineer | Data Analyst | Financial Systems Specialist

I am a data professional with a background in financial services, currently evolving my expertise into Data Engineering. I thrive on building systems that don't just "show" data, but move and transform it efficiently.

πŸ’Ό Professional Experience & Impact

Financial Securities Automation:

The Challenge: Reporting for Bonds, OMO, and Treasury Bills was trapped in manual Excel sheets, causing high latency and errors.

The Build: Engineered a robust SQL Server ETL pipeline to centralize fragmented security data.

The Result: ⚑ Reduced reporting turnaround from hours to seconds and significantly improved data integrity.

πŸ“Š ABZ Limited | Credit Risk & Loan Analytics:

The Challenge: Investigating a surge in loan defaults within a micro-lending portfolio.

The Build: Developed an end-to-end Power BI suite utilizing DAX and Power Query to segment borrower risk.

The Result: 🎯 Identified unexpected default trends in mid-grade borrowers (B, C, D), leading to a refined credit strategy.

🌱 What I'm Currently Building

Right now, I am deep-diving into data engineering and Go (Golang) to understand the performance side of data processing. I'm moving beyond just analyzing data to building the high-speed engines that carry it.
