What I'm looking for

I seek a data-focused role in a mission-driven health or development organization where I can apply M&E, KenyaEMR and Excel skills to drive evidence-based program improvements, mentor staff, and support data-informed decision-making.

I am a dedicated professional with a background in medical billing and coding, complemented by experience in dispatch operations. I enjoy working in structured environments where attention to detail and accuracy are essential, especially when managing claims, coding records, and ensuring smooth coordination of tasks.

Beyond my professional skills, I have a strong interest in learning new systems, improving workflows, and staying updated with industry standards. I also enjoy problem-solving, organizing processes, and communicating effectively to keep operations running efficiently. In my free time, I’m interested in personal development, technology, and finding ways to improve productivity both professionally and personally.
