Hey, I'm Onyinyechi.Finance, Admin & Data Support Professional.
I work across financial and administrative support, customer chat support, social media management, financial writing, and SQL-based data analysis — for teams and clients on remote and freelance engagements.

What I take on
Six areas of work, each drawing on the same habits: careful reading, exact language, and follow-through on detail.
Administrative & Finance Support
Records management, invoice processing, correspondence, budget tracking, and account reconciliation for finance teams.
Customer Chat Support
Live chat support handling inbound inquiries, order issues, and account questions, with prompt escalation and clear documentation.
Financial Writing
Clear, accurate content on financial topics and investment guides, informed by ongoing study toward the ICAN qualification.
Social Media Management
End-to-end social media activity across LinkedIn, Facebook, Instagram, and Twitter, including content planning and analytics.
Data Analysis
SQL-based analysis for reporting and reconciliation problems, from raw queries to board-ready summaries.
Financial Analysis & Audit Support
Financial statement analysis, risk assessment, and audit support, including forecasting and modeling exercises.

SQL & Data Analyst Projects
Seven independently graded projects on DataSimHQ, resolving revenue reconciliation and data quality problems in relational databases for a simulated retailer. Average score 93/100.
Isolating an NGN 18.4M revenue gap
Built a single status-level query with window functions to show gross revenue, net revenue, and the exact gap caused by cancelled, returned, and refunded orders — for a CFO's board presentation.
Four-year revenue baseline
One query returning total order count, date span, and total revenue (NGN 2.3B across 2021–2024) as the reference point for all later period-specific reconciliation work.
Reconciling two conflicting October dashboards
Explained a NGN 56.9M vs NGN 38.5M discrepancy between a sales dashboard and the finance system with a single status-level breakdown, ahead of a board presentation.
Resolving three conflicting customer counts
Used four subqueries to show how three different customer-count figures (2,331 / 2,131 / 2,200) were each produced, and confirmed 2,131 as the defensible, deduplicated figure.
