What I'm looking for

I’m looking to lead financial operations with strong tax, reporting, and advisory impact—helping teams stay compliant, optimize costs, and improve decision-making through automation and real-time insights.

I’m a Senior Accounting Manager and Senior Accounting Professional with 5+ years of progressive expertise in financial management, tax planning, reporting, and strategic business advisory across fintech and multinational settings. I’m actively pursuing CPA Alberta certification to deepen my knowledge of Canadian accounting standards and regulations.

In my most recent role at Swipebill Technology (Float YC’20), I spearheaded financial advisory delivery for 100+ SMBs—driving 85% lead-to-conversion and 90% client retention. I also optimized accounting operations by implementing cloud-based accounting software, cutting manual effort by 50% and reducing operating costs by 20%, while improving reporting speed by 30% through automated financial dashboards.

Previously at Accounteer Smart Cloud Accounting Limited, I increased revenue by 15% through accurate GST, Company Income Tax, and WHT filings for 150+ SMBs, including leading tax audits. I managed AR/AP to triple net asset value for three FMCG companies, built financial models that supported a USD 10M investment round, and improved reporting accuracy by 25% by creating SOPs for fixed assets, inventory management, and tax assessments.

Earlier as a Finance Analyst at RVRB Innovation by STEMCafe and as an Accountant at Brain-Point Edukonsult and Jos South Local Government Council, I strengthened my foundation in month-end close, reconciliations, general ledger accuracy, payroll compliance, and audit readiness—always pairing analytical rigor with process improvement and cross-functional leadership.
