About

For over 15 years, I have been working at the intersection of climate policy, sustainability disclosure, and capacity building across Southeast Asia, helping governments, cities, and corporations translate environmental commitments into measurable action. My work spans three interconnected areas: Sustainability disclosure Supporting companies and sub-national governments to disclose through the CDP platform, aligning with ISSB/IFRS sustainability standards and driving capital flows toward credible landscape and jurisdictional approaches (LA/JA) in Indonesia and the ASEAN region. Climate policy & advocacy Advising on transboundary haze pollution control, peatland management, and disaster risk reduction, including roles at the ASEAN Secretariat and JICA, where I bridged technical expertise with on-the-ground implementation. Knowledge & capacity building Designing and delivering in-person and virtual workshops for cities, states, and regions on forest and climate issues; producing knowledge products, policy briefings, and stakeholder engagement programs across Southeast Asia. I am currently completing a Master's degree in Sustainable Finance & Sustainable Development at Universitas Udayana, deepening my expertise in climate finance, AI applications in sustainability, and IFRS disclosure frameworks. Languages: English and Bahasa Indonesia (professional working proficiency). I am open to roles in sustainable finance, ESG advisory, climate policy, and sustainability disclosure — particularly those focused on ASEAN, Indonesia, or emerging markets. Feel free to connect or reach out. 👌🏽
