What I'm looking for

I'm looking to keep growing as a GenAI/Data Scientist in a professional, collaborative environment where I can build reliable AI tools and data solutions.

I've built RAG chatbots, PR review automation, and data engineering pipelines at Ominimo Insurance, including call center audio analytics that transcribes, masks sensitive data, and generates operational reports.

During internships at Standard Sharing Software and Pixemantic, I developed a multi-agent log investigation system using Groq LLMs and RAG, and fine-tuned Mistral 7B for a medical chatbot. I also built a CNN-based breast cancer detection system and enjoy turning applied AI research into reliable tools.
