Cross-Platform Review from Kristine Wilson
I've been working with AllianceTek for over five years, and they have been an invaluable technology partner. They seamlessly took over a complex project from previous vendors and have since played a crucial role in managing both our app and website.
Their team is highly knowledgeable, resourceful, and adaptable, with expertise across various platforms. No matter the challenge, they approach each project with patience, professionalism, and a problem-solving mindset. Their ability to listen, provide clear solutions, and ensure smooth execution has made them a trusted extension of our team.
Beyond their technical capabilities, what truly sets AllianceTek apart is their commitment to client success. They are responsive, proactive, and consistently go above and beyond to deliver results. I highly recommend them to anyone seeking a reliable, skilled, and collaborative development partner.

Cross-Platform Review from Mark Gratiot
In addition to building out a native remote inspection app for iPads, Zco concurrently ported the software to a Xamarin platform for Windows users. Zco has released nine major iterations of the iPad app, each available in the App Store, as well as the initial version of the cross-platform Xamarin build. Their nimble team boasts a wide breadth of skills to match any given situation. Having clear documentation upfront has reduced onboarding time.

Mobile App Development Review from Katie Matter
Zco Corporation provided full-stack mobile app development to an educational resource retail organization. They worked in Unity to build a cross-platform resource for users to advance through various curricula. The app has successfully been moved into preproduction and the second phase of development, completely satisfying project stakeholders with the quality of both its designs and functionality. The Zco Corporation team is highly creative and collaborative throughout their work.

Startup Review from J. Michael Webb
J. Michael Webb from CheckMySpot chose Zco Corporation for app development due to its expertise. Zco adeptly developed a hybrid mobile teledermatology platform and an admin website, demonstrating excellent communication, responsiveness, and innovation. Despite the project's evolving and innovative nature, Zco seamlessly integrated Webb's intent and met all challenges, leaving him with no suggestions for improvement. (Verified via email/call)

I recently completed a Quality Assurance internship at Net Solutions, and it was a fantastic experience. I had the opportunity to work alongside a highly skilled team that truly values precision and innovation. From manual testing to getting hands-on with automation tools, the mentorship I received helped me bridge the gap between academic theory and real-world application. The culture is collaborative, and I felt like a valued member of the team from day one. Highly recommended for anyone looking to kickstart their career in QA
