UI/UX Design: Interfaces That Work as Well as They Look
Every digital product makes a promise the moment a user lands on it. The promise is simple: this will be easy. The experience of navigating a well-designed interface — finding what you need without thinking, completing a task without friction, understanding a product's value without reading a manual — is the result of deliberate design decisions made at every level of a product, from its information architecture down to the pixel-level detail of a button state.
At bf agency, we design digital interfaces for web products, SaaS platforms, and mobile applications. Our process combines UX thinking with rigorous UI craft to produce interfaces that perform as well as they look. We work in Figma and deliver production-ready files that give developers exactly what they need to build without guesswork.
Why UX Comes Before UI
The temptation in many design projects is to start with visual design — to open a design tool and begin making screens look beautiful. This is a mistake. Before a single pixel is placed, the structure of the product must be solved: how is information organised, what can users do at each stage, where do flows start and end, what happens when something goes wrong.
UX design is the discipline of answering these structural questions before aesthetic ones. It requires understanding the user's goals, the business's objectives, and the constraints of the technology. When UX is done well, UI design becomes a matter of communicating clear decisions rather than solving structural problems through visual decoration.
The UX Process: From Research to Validated Structure
User and Stakeholder Research
For products where the user base is not yet fully understood, we begin with research. This includes stakeholder interviews to align on business goals and technical constraints, and user interviews to understand the tasks, contexts, and frustrations of the people the product is designed for. We also conduct competitive analysis: what do existing solutions do well, where do they fail, and what does the target product need to do differently.
Research findings are synthesised into user flows and key scenarios — the specific situations the product must handle well. These scenarios become the test cases for every structural decision that follows.
Information Architecture and User Flows
Information architecture defines how content and functionality are organised within the product. For complex products, we create site maps or app maps showing every section and sub-section and how they connect. For simpler products, we document the primary user flows as a series of steps with decision points.
This stage surfaces structural problems before any design time is spent on them. A navigation structure that seems logical in a spreadsheet often reveals friction when traced as a user flow. Fixing architecture at this stage is far less expensive than fixing it after screens have been designed.
Wireframing
Wireframes translate information architecture into screen-level layouts without visual styling. Each key screen is sketched in low fidelity — enough to show what content appears, in what priority, and what interactions are available. Wireframes are tools for thinking and for communication, not deliverables in themselves.
We review wireframes with clients and, where possible, test them with users before proceeding to visual design. A usability issue caught at wireframe stage costs a fraction of what it costs to fix after the UI has been fully designed and built.
The UI Process: Translating Structure Into Visual Design
Visual Design and Component System
With validated structure in place, UI design begins. We design key screens first — the ones that establish the visual language of the product: the dashboard, the primary listing view, the detail screen, the key form. Getting these right sets the tone for everything that follows.
As we design, we build a component library in Figma. Every button, input field, card, navigation element, and state is designed once as a reusable component and then used consistently across all screens. This approach ensures visual consistency, speeds up the design of subsequent screens, and creates a clear map of what development needs to build.
States and Edge Cases
Real products are full of states that are invisible during initial design: empty states when there is no data to show, loading states while content is being fetched, error states when something goes wrong, success states when an action is completed. These moments define whether a product feels polished and considered or incomplete and frustrating.
We design all significant states for every component and screen. This is not optional — it is essential for both user experience quality and development clarity.
Prototyping
Interactive prototypes connect screens into flows that can be clicked through and tested. Prototypes are essential for communicating interaction behaviour to stakeholders and for identifying usability issues before a line of code is written. We build prototypes in Figma for key user flows and test them with users or internally before finalising the design.
Figma Delivery and Developer Handoff
We deliver all UI designs as structured Figma files with clearly named layers, organised frames, and a complete component library. Design tokens — the values for colours, spacing, typography, and radii — are defined in a way that maps directly to how they will be implemented in code. We annotate interactions and non-obvious behaviours so that developers have the information they need without requiring extensive design support during the build phase.
Good handoff is part of the design service, not an afterthought. A Figma file that requires constant interpretation during development is a sign of incomplete design work.
