What Our Clients Say

“The QuartzDevs team was able to implement a solution for our payment gateway issues and saved us tens of thousands of dollars in lost revenue, as well as time spent by our accounting, sales, and customer service teams to remedy these issues.”

Manager, Web Applications @ CALI Floors

“The QuartzDevs team of three engineers was proactive and assumed numerous responsibilities. Their lead was leading various aspects of the project's engineering work we were involved in.

What a Long Engagement Looks Like

These are not one-off builds. Team size, scope and ownership change as the product does.

See how the two team models work in practice: dedicated development team and IT staff augmentation.

  • Capacity follows the work

    CALI Floors has run with 2-4 engineers over time. Today, 3.5+ years in, one engineer keeps the B2C and B2B platforms in maintenance.

  • Scope grows from the first deliverable

    At GoStudent a company-wide UI component library with live Figma token updates came to serve 4 internal products, and the engagement also included leading a team of 5 engineers on the B2C chat micro-frontend.

  • One client, more than one project

    Save the Children International worked with a team of 3 on two separate projects over 1.5 years: an internal support chatbot and a crisis-monitoring system.
