  • “We engaged with BigBinary with a fairly urgent need for a complex Rails/React service. Their developers quickly gathered context and began work. They operated as a seamless extension of our team and produced very high quality code. Our own developers got a lot of value from working with them. Ultimately, the project was completed on time with high test coverage and stability. We are consistently building on the foundation they laid, and are very pleased with the results. I am looking forward to future opportunities to work with BigBinary in the future.”

We have been working with them for over a year, and not only is their development talent including React top-notch, but they also allow us to easily staff up and scale down as needed for surges around specific product features, which is extremely beneficial to us as a startup. I cannot recommend BigBinary highly enough!”
