Can you hire UI developers on an hourly basis or for project-based tasks?

Whether you hire an expert for a full- or part-time position, you’ll have the control and flexibility to scale your team up or down as your needs evolve. Our UI developers can fully integrate into your existing team for a seamless working experience.

What is the no-risk trial period for Toptal UI developers?

We make sure that each engagement between you and your UI developer begins with a trial period of up to two weeks. This means that you have time to confirm the engagement will be successful. If you’re completely satisfied with the results, we’ll bill you for the time and continue the engagement for as long as you’d like. If you’re not completely satisfied, you won’t be billed. From there, we can either part ways, or we can provide you with another expert who may be a better fit and with whom we will begin a second, no-risk trial.
