Bright Green Beginnings

Through a combination of voluntary work and travel through South-East Asia, I realized that access to opportunity, basic human rights, environmental safety, and wealth are not equally distributed and should not be taken for granted. It made me conscious of my privileges growing up and created a vision to make a positive change. Upon meeting incredibly bright individuals, I was first introduced to 'sustainability' and the complex challenges we have to solve.

Becoming a Project Manager

Through my bachelor's program in international project management with a focus on sustainability, I have had hands-on experience with sustainability projects in the private, public, and non-profit sectors. The diverse projects focused on poverty, inequality, change management, renewable energy, sustainable finance, remote work, and making sustainability part of a company’s mission.

Road to Sustainability Consultant

Given my academic background in sustainability project management, I was able to get experience in end-to-end innovation. From identifying the challenge to implementing and monitoring impact. Over the years, I have transitioned from a sole project manager to a combination of a sustainability consultant and a project manager. This allows me to consult on sustainability challenges while ensuring the solution is implemented.
