Message

At Econet Wireless Zimbabwe (Econet AI), I engineer Yamurai, an agentic AI system that automates EcoSure insurance claims through WhatsApp and web interfaces, with document OCR microservices. I also work on ChiShona language model alignment using vector embeddings.

At Econet Fintech - EcoCash, I led the core mobile money transformation, coordinating more than 100 professionals to implement a new platform serving 15M+ users, with zero critical downtime during cutover.

I was also technical lead for the Payment Gateway, Online Merchant Payments, and merchant onboarding systems. I designed Spring Boot and Spring Cloud microservices and integrated GMM and XGBoost pipelines for real-time fraud reduction.

Earlier, at Telecel Zimbabwe, I built TeleCash wallet features and optimized backend performance. At Leap Inventions Inc., I developed Django and Flutter solutions, including invoicing, payroll, and billing modules.
