This company was my client. in 2020

We have been working with Andersen for almost two years now, profiting from the experience of their backend, frontend, DevOps and QA (both manual and automation) engineers. The team, which they provided us with, has been responsible for the development and support of one of our components and up until now this collaboration has been a huge success for both sides.

Other. in 2021

We were looking for a contracting agency that could source top talent in design, business analysis, and engineering. We found Andersen through a mutual connection. Their prompt communications, structured process, and quality of talent all contributed to our decision to source talent from them. Thanks to their team, we have significantly sped up our time to market estimate. We are constantly able to deliver new features sooner than expected thanks in large part to the structure their talent provides to our business processes. From ideation, to execution, and ultimately to maintenance they contribute every step of the way!
