KenyaWhat I'm looking for
I am a versatile professional with over five years of experience in data annotation, customer support, community moderation, virtual assistance, and web development. I specialize in image, text, audio, and video annotation to train and validate AI/ML models across domains such as autonomous driving, healthcare, and e-commerce.
I consistently maintained accuracy above 98% on large-scale annotation projects and performed quality checks and peer reviews to ensure dataset integrity. I also resolved high-volume support workflows, handling 1,000+ monthly tickets with a 95% satisfaction rate while producing FAQs and troubleshooting guides to improve team efficiency.
As a community moderator, I grew and managed English-speaking Discord and Telegram communities for Web3 projects, reducing spam and scam activity by 90% and increasing engagement. I provide virtual assistance and data-entry support to executives and e-commerce/Web3 clients, delivering accurate reports and CRM management.
I bring a strong technical foundation—Python, MQL4/5, SQL, Java, PHP—and web development experience with Shopify, WordPress, and Wix, enabling automation and practical tech solutions. I hold a BSc in Actuarial Science (First-Class Honors) and approach work with a focus on reliability, accuracy, and continuous improvement.
