Mariia B.

I design and build interfaces for SaaS and web applications directly in code, combining product design with React implementation. I can help you simplify a complex workflow, redesign a feature, refine existing UI, or build reusable components for your design system. You can bring me in for a focused project or flexible part-time support, from a single screen to ongoing product work. My experience spans analytics platforms, B2B applications, and operational tools. In previous projects, I’ve owned design systems, brought Figma libraries into versioned React packages, and worked through complex navigation and product workflows. My work covers both how an interface looks and how it behaves: hierarchy, interactions, responsive layouts, and loading, empty, and error states. What I can help with: • Feature design and implementation — turn a product requirement into a clear user flow and working interface. • UI refinement — improve typography, spacing, visual consistency, responsiveness, and interaction states in your existing application. • Design systems — build or extend reusable components, design tokens, and documentation. • Interactive prototypes — explore and test a workflow in code before committing to a larger build. • Ongoing product support — work alongside your team on design decisions and front-end implementation. I work directly in the browser and your codebase, so you can review a working interface as the design develops. My tools include React, TypeScript, and AI-assisted coding tools. I set the design direction, guide implementation, and review the resulting interface and code. I also work in Figma when it fits your team’s workflow. I’m available for short projects, flexible ongoing collaboration, and contract-to-hire. Share what you’re building and what needs to work better, and we can define a practical first task.
