What I'm looking for

I seek entry-level roles focused on climate adaptation, sustainability planning, or GIS-related analysis where I can apply data-driven solutions, grow technical skills, and collaborate on impact-driven projects.

I am a motivated, detail-oriented senior pursuing a B.S. in Climate Science with a specialization in Design and Planning for Sustainability and a minor in Geology. I combine strong communication and teamwork with practical experience in data entry, office systems, and customer-facing roles to advance climate adaptation and mitigation in the built environment.

I have developed skills in GIS-adjacent workflows, Microsoft Office (Word, Excel, Outlook), appointment scheduling, and client communication through administrative and retail roles. As a dependable contributor and fast learner, I bring a commitment to sustainability, collaborative problem solving, and translating data into actionable planning outcomes.
