What I'm looking for

I'm looking to apply my data annotation, Python, testing, and data-quality experience to practical products, especially tools and services that improve real-world user experiences.

At Mapbox, I process and categorize user-submitted map feedback to identify inaccuracies and improve data quality across global maps. I collaborate with internal teams to keep location-based services accurate, useful, and aligned with real-world user intent.

I also support internal-tool development and testing, using JavaScript and SQL for small coding tasks that improve functionality and performance.

Previously at WANNA, I performed image segmentation and markup in GIMP, integrated 3D models into photographs for virtual try-on experiences, and configured model key points for AR web applications. I installed and deployed a Python-based markup application, tested applications, identified bugs, and recommended reliability improvements.

My earlier customer-support work strengthened my ability to manage orders, communicate with international users in English, resolve issues quickly, and use customer feedback to improve service quality.
