What I'm looking for

I seek roles applying ML and data science to real-world problems, with collaborative teams, clear impact metrics, and opportunities to build production-grade models and analytics.

I am a data scientist with hands-on experience training multimodal AI, building dashboards, and delivering actionable analytics for NGOs and research projects.

At OpenAI I contributed to training a multimodal model by authoring and refining 5,000+ detailed prompts, designing image-plus-text tasks, and ensuring prompt clarity and edge-case coverage to improve model reasoning.

I built backend data pipelines and visualizations for an award-winning RShiny opioid dashboard, and developed production-ready APIs and scalable MongoDB architectures for an EdTech solution that received Forbes recognition.

I enjoy turning complex data into practical impact—matching mentors to 1000+ vulnerable adolescents, informing organizational decisions with advanced analysis, and creating tools that improve access to information and learning.
