Ruby Mamistvalove is a Senior Frontend Developer and founder of Daino Inc. with 10 years of product-focused engineering experience based in Tel Aviv. She built and scaled note-taking apps that have amassed over 1.5 million downloads and revenue, and continues to develop complementary projects like get-notes.com and notes-foss.com. Skilled across C++, QML, React/Next.js and mobile stacks, she has shipped performant custom editors, cross-platform assistants, and production-grade React Native apps with Python/C++ backends. At Factify she now applies that UI-first mindset to larger frontend systems while maintaining hands-on contributions to open source UX improvements. Colleagues describe her as someone who consistently connects disparate ideas into practical features—evident in UI refinements like macOS-aware window management and thoughtful icon and layout work. Her blend of product intuition and low-level implementation lets her move quickly from concept to revenue-generating software.
