UI Design

In our web application UI design services, we prioritize functionality over aesthetics, ensuring that the design serves a functional purpose.

How to design a web app: our process

We collaborate with diverse clients across industries such as FinTech, Web3, e-commerce, retail, and beyond, so our style is molded by their specific objectives and preferences. Yet, a fundamental aspect consistently guides our design process: a human-centered approach.

When it comes to web application design services, our methodology is not confined to a fixed set of traits. Our style is molded by your specific objectives.


Conducting UX research 

Our web app design journey begins with the initial phase, where we dive into understanding the project's goals, who it's intended for, and the market it operates in. UX designers conduct thorough user research, analyze competitors, and gather requirements to outline the project's scope and objectives.


Building wireframes & prototypes 

Next, we craft wireframes and prototypes to sketch out the web app's design and functionality. This phase enables us to envision how the application will be structured and how users will interact with it, opening the door for early feedback and fine-tuning.


Crafting visual design

After completing the extensive UX research and user experience design phases, our UI designers take the reins in shaping user interfaces. However, before delving into visual design, it's essential to establish the preferences. To accomplish this, we create moodboards that effectively communicate the desired visual directions.


Moving to the app development

Once the product is designed, tested, and refined, we gather all the insights collected throughout the design process — such as customer journey maps, user flows, design visuals, sketches, components, guidelines, prototypes, and style references — and then pass all of this to the engineering team, whether it's your in-house team, our partnered development agency, or Lazarev.'s Webflow developers.


Testing and iterating 

We carry out a Design Quality Assurance once the web application is coded to ensure everything is spot-on. We put the digital product through testing to pinpoint and fix any bugs, usability concerns, or performance hiccups. User testing is instrumental in gathering feedback and insights for making additional refinements.
