From early product ideas to launch-ready mobile interfaces, I help teams clarify user flows, shape intuitive screens, and deliver reliable app experiences that work smoothly across devices.
Hello, my name is John Watson. I am an app designer and app developer with 6 years of experience creating mobile applications, product interfaces, and app-focused digital services.
What I do for you
Mobile app interface design with clear user flows, accessible screens, consistent components, and visual systems that support product goals.
Application development for mobile-first product flows, interactive tools, and service experiences using maintainable code and performance-minded implementation.
Clickable prototypes, interaction models, screen states, and product demos that help teams validate app ideas before development.
Reusable app components, spacing rules, typography guidance, and interface specs that help product teams move faster without losing design quality.
work experience
Led the design direction for mobile app experiences, product launches, and service interfaces. I coordinated with strategists, developers, and client teams to create clear user flows and conversion-focused app journeys.
Built app-focused interfaces for SaaS products, internal tools, and customer portals. My responsibilities included translating design files into reliable application code, improving performance, and documenting reusable UI patterns.
Partner with founders and small teams to plan, design, and launch app experiences that clearly solve user problems. Projects typically include discovery, user flows, wireframes, app UI design, implementation support, and post-launch improvements.
what clients say
John helped us turn a vague app idea into a clear, polished product experience. The process was organized, the design felt distinctive, and the final screens worked smoothly on every device we tested.
Product Lead
We needed a designer who could also understand app development constraints. John delivered thoughtful screens, clean implementation notes, and practical improvements that made handoff simple.
