What I'm looking for

I’m seeking a position that allows me to apply my data entry, CRM, and reporting skills in a fast-paced and detail-oriented environment. I value accuracy, teamwork, and opportunities to grow while contributing to smooth and reliable operational processes

I am a customer-focused technical professional with hands-on experience in CRM, data management, and process improvement — now specializing in AI operations and data workflows. I combine a Computer Science foundation with practical experience supporting clients, managing digital projects, and improving data accuracy for enterprise teams.

I have strong capabilities in AI-assisted workflows, prompt engineering, data annotation, and model evaluation, as well as experience supporting customer-facing teams in corporate environments such as Coca-Cola Beverages Kenya and Stima Sacco. My background includes maintaining CRM datasets, optimizing onboarding processes, and creating structured communication systems that improve customer satisfaction.

I excel in roles that require accuracy, analytical thinking, and cross-functional collaboration. I’m quick to learn new AI tools and have practical experience with ChatGPT, Claude, Perplexity, Notion AI, Zapier, and CRM platforms like Microsoft Dynamics.

I’m seeking opportunities in AI operations, model testing, technical support, customer success for AI products, data annotation, or prompt-based content creation, where I can combine problem-solving, communication, and technical skills to help teams deliver better AI-driven experiences.
