What I'm looking for

Seeking a remote-first Data Analyst role where I can apply my SQL, R, and Tableau skills to high-impact datasets. I thrive in asynchronous environments that value documentation and technical rigor. As an Engineering student, I look for teams that offer mentorship and solve complex problems. I provide 24/7 power/fiber reliability and am eager to help a global team turn data into strategy.

The Analyst with an Engineer’s Mindset

I am a Google Certified Data Analyst and 100-level Mechanical Engineering student at Ahmadu Bello University. I specialize in optimizing complex systems through data-driven strategy. Using SQL (BigQuery), R, Spreadsheet, and Tableau, I transform raw data into measurable business growth.

Impact & Achievements:

Scalable Data Engineering: Architected a modular SQL pipeline for the Cyclistic Bike-Share project, cleaning 1.9M+ rows of data with 99.9% integrity. This analysis identified a 15% membership conversion opportunity by uncovering distinct casual-user behavioral trends.
Predictive Customer Intelligence: Developed an R-based RFM model to segment 4,300+ unique customers. By quantifying "At-Risk" vs. "Champion" cohorts, I provided a framework to reduce churn by an estimated 12% through targeted retention.
Operational Efficiency: Streamlined reporting workflows using automated spreadsheets and Tableau, reducing manual data processing time by 30% and enabling faster stakeholder decision-making.

Why I am "Remote-First": With two years in customer-facing roles, I maintained a 95% satisfaction rating at Divine Uche-Pat Venture. I combine "Analytical Empathy" with technical rigor, ensuring data insights solve real human problems. My remote setup is enterprise-grade:

Infrastructure: 24/7 power backup and high-speed fiber-optic internet.
Reliability: Expert in Slack, Zoom, and Git; available for EST, CET, and GMT.

Interests: I am passionate about system optimization and mathematical modeling. I am looking to help a global team turn data into strategy while I continue my academic journey in Engineering.
