POS System

Overview

POS system for restaurant, café, and HoReCa staff

Focused on fast and error-free order management in medium to high-load environments, with cloud service and modern integrations.

My Responsibility

What I worked on

UX research, competitor analysis, and the development of key features in collaboration with the team — order creation, modifier logic, payment scenarios, and other complex processes requested by the client.
Analysis and improvement of the design after testing and feedback from the product owner.
Developing the design system and working on marketing materials.

Design Process

How I approached it

01Researched existing restaurant workflows and pain points

02AI prototyping — earlier wireframes

03Designed high-fidelity screens for core flows

04Iterated based on internal feedback

Empathy

Understand the needs and challenges of business and customers. Research of competitors and data analysis, feedback, information collection.

Define

Clearly articulate the problem statements based on insights gathered from the empathy phase.

Ideate

Working with ideas, design options, brainstorming with the team, using AI tools.

AI Prototype

Develop prototypes with different ideas using AI tools to visualize and test the proposed solutions. And Work with UI design.

Test

The team and the first clients are testing the design, collecting initial feedback and improving the design.

Problem & Solution

Challenge

Designing without direct access to users

Working within a cross-functional team from the product's earliest stages, the main challenge was finding quality UX solutions without direct access to end users — navigating owner-driven requirements, fast-moving feature scope, and the specific pressures of HoReCa operations.

Solution

Research-grounded decisions

Grounded every decision in secondary UX research, established HoReCa design patterns, and a genuine curiosity about how restaurants and cafés actually work. Brought structure and clarity to complex flows — order creation, modifier logic, payment — where the margin for error is zero.

Developer Handoff

Working closely with the team

Throughout the project, I worked in close collaboration with developers — participating in regular syncs, clarifying design intent, and adapting solutions based on technical constraints. Before presenting decisions to the product owner, the designer and developer would validate solutions together internally, ensuring feasibility and catching edge cases early.

Outcomes & Impact

What was delivered

⟢

First functional versions shipped

Core POS flows — order creation, modifier selection, checkout, payment — designed and delivered as working product versions in collaboration with the dev team.

⟢

Iterated on real feedback

Design decisions were refined through ongoing feedback cycles with the team and product owner, improving usability and reducing friction in key staff workflows.

⟢

Complex flows made simple

Multi-step flows like modifier logic and table management were structured to reduce cognitive load for staff — clear hierarchy, minimal taps, zero ambiguity.

⟢

Design system foundation

Established consistent patterns and components across POS features — creating a foundation for faster design and development in subsequent product iterations.
