ZimbabweWhat I'm looking for
At Aventus IT, I lead a five-engineer team building lending and credit aggregation platforms serving 1M+ registered users. I designed shared TypeScript packages powering four production apps, led a React and TypeScript migration that cut bundle size by about 35%, and improved mobile LCP from roughly four seconds to two.
Previously at Cuby Technologies and Innowise, I built microfrontend platforms, automated CI/CD delivery, interactive 2D/3D construction visualizations, real-time edtech products, and Node.js APIs. I enjoy shaping frontend architecture, mentoring engineers, and using AI-assisted workflows to improve delivery and code quality.
