I am a dedicated financial professional with a proven track record in fund and partnership accounting for the past 9+ years. With a career spanning multiple top-tier financial firms, I bring a wealth of expertise and leadership to the table. Currently, I serve as a Controller in the Fund Division at 500 Global, a global company specializing in finance. In this role, I lead financial oversight by meticulously reviewing and approving financial statements, footnotes, and capital account allocations prepared by third-party administrators. My role as a point of contact and collaborator with fund managers ensures seamless fund-related operations. I'm also committed to process enhancement, cash flow forecasting for the funds I oversee, having recently revamped transactional data retrieval and analysis procedures, streamlining GP book preparation for quarterly and year-end tax reporting. My previous tenure at Carta, Inc., a renowned tech company, showcased my managerial prowess as a Fund Controller. In this capacity, I skillfully led and guided a team of 4-8 members, fostering their growth and optimizing performance. I managed day-to-day operations and cyclic tasks for my designated clients, while nurturing strong client relationships. My expertise in venture capital and fund accounting proved pivotal in delivering informed insights to clients, empowering their strategic decision-making. Prior to Carta I worked at Blackrock, where I was an Associate in NAV Oversight for an Alternative Open-End Fund of Funds platform. Here, I excelled in coordinating complex regulatory processes and tax items, establishing myself as a vital liaison for internal and external stakeholders. Simultaneously, my responsibilities included overseeing financial reporting for multiple funds autonomously, showcasing my adeptness in US GAAP and financial management. My journey began at The Carlyle Group where I started as a Staff Account and then became a Senior Accountant for US Real Estate and Japan Buyout. In this role, I managed rigorous US GAAP financial reporting for a portfolio of funds, consistently surpassing aggressive deadlines. I was recognized for my leadership by conducting trainings and supervising junior accountants.
