Lead Software Engineer

Hi, I'm Gabriel Menacho

Senior software engineer

I lead front-end delivery for large product teams: React and TypeScript applications, shared component libraries, and Storybook-driven design-dev workflows. I care about test-backed quality (Jest, Cypress), SOLID and clean architecture, and CI/CD with GitHub Actions so releases stay fast and predictable. My recent focus includes enterprise UX at scale, e-commerce surfaces, and AI-adjacent product work such as retrieval-augmented experiences and agentic workflows - always grounded in measurable outcomes for users and the business.
