What I'm looking for

I’m looking for a Management Accountant or Finance Manager role where I can run finance operations end-to-end, strengthen treasury and compliance, and drive finance transformation—automation, faster close, and decision-ready reporting across multiple regions.

I lead full-cycle finance operations for USA, Singapore, and Mauritius portfolios, overseeing $25 Million in assets while ensuring strict adherence to US GAAP & IFRS.

I’m known for turning finance processes into measurable outcomes—automating reporting and reducing monthly close time by 20%. From treasury operations and multi-currency liquidity forecasting to preparing audit schedules, reconciliations, and multi-jurisdiction documentation, I coordinate teams and clients to deliver accurate, timely, compliance-first reporting.
