Emerline is an important part of our strategic team!

Emerline has been our technology partner since late 2012. In the early years I thought that would be a short-term gap fill until I could afford to hire my own technical team in the US. But they have consistently met the demands of our growing company and helped us build what we believe is the industry's best solution option. Emerline provides high quality work, so much so that our platform's reliability and accuracy has been mentioned by our largest customer's internal vendor survey repeatedly. The individuals we work with aren't just contractors, they are an important part of our strategic Team and we enjoy working with them every day!

My experience with Emerline has been great

The team was hired to design and develop the Echospectra mobile and web applications, as well as to integrate them with a variety of cloud services. A critical requirement was to rapidly develop the apps in an agile manner, quickly implementing important stakeholder and user feedback as it came along, and fixing any outstanding bugs. The team managed to accommodate this kind of agile, change-driven process successfully. Thanks to their rapid development approach, we've been able to build the initial app versions and then continuously iterate on them to refine our product offering and make sure it meets and exceeds customer expectations. I highly recommend them to anyone looking for a reliable partner who delivers on time and on budget.
