At Lannang Group, I optimize sales and billing workflows through SOP adjustments and job delineation, and directly assist the President with employee management. I also manage HR projects focused on employee retention and morale.

I lead monthly financial reporting alongside the accountant and financial staff, supporting bookkeeping, cash tracking, and tax compliance.

At Gentree Fund Asia, I assisted with the Philippines deal pipeline, investment committee meetings, and KPI monitoring for portfolio companies. At AZC, I led client GTM projects and automated a business development prospect pipeline and outreach agents.
