Our Design Process

User Research and Technical Discovery

User Research and Technical Discovery

Our design projects begin with a research and discovery phase to determine what we're going to design and how we're going to design it. The discovery phase includes creating user personas, user stories, site architecture, visual design options, and a style guide.

Style Guides, Wireframes, High Fidelity Designs

Style Guides, Wireframes, High Fidelity Designs

Next we create wireframes to demonstrate the general layout of each screen, and three style concepts for you to choose from, each with its own unique look and feel. Then we create high fidelity designs of each feature, and each view of the application or website.



Finally we link all of the designs together and create a Clickable Prototype which demonstrates features and functionality of the app. As a final step we build a detailed development estimate, and create a development proposal that includes estimated costs, schedules, team size, technology recommendations, project milestones, etc.

Client Testimonials

Bunk1 Application

The experience I've had with other firms is in direct contrast to what FullStack did. I'm comparing them with two other firms I worked with in the past. They care a lot about what their clients are doing. They bring their ideas and concepts to the table. I felt like they were on my team. They added a lot of value in terms of ideas and continue to do so. No matter who's working on the project you feel like they care about the work that's being produced.

FullStack Labs' managers have been engaged throughout. The whole project management staffing, matching team to task has been fantastic. All their staff is very committed. I'm very aware of how much bureaucracy there is in the tech world, and we've gotten nothing but solutions. I am totally happy with their approach to everything, their integrity, honesty, the whole thing. It's great.

MomKit Application

We were very happy with the way the whole process was facilitated. We started talking to FullStack Labs three months before we signed any contract with them. We met with them in person several times. We wanted to find out what their philosophy is. Both Brian and David are fathers with young children, so they understand the importance of the work we are doing. That shows through in their work. It was obvious they cared deeply.
