If your looking to find top developer resource, Lemon.io is the place.

Lemon.io has been a game changer for us. Speed, clarity, and quality were there from day one, but what really impressed me was how much they care about getting the right fit, not just filling a role.

We had some specific requirements, and the candidates surfaced were consistently high quality and well aligned. The team checked in regularly, handled onboarding smoothly, and genuinely went the extra mile to keep things simple.

It’s rare to find a service that combines great talent with great people. Lemon.io absolutely does both, and we’ll be continuing to work with them. Diana is a superstar.

Lemon cares a tremendous amount about finding high quality developers that are the right long term fit. We had some specific requirements and Iryna was able to find some great options that were all really qualified. They checked in several times during the engagement and made sure the start and kickoff for the dev was well handled. Will be planning on working with them well into the future.

Building our tech startup would not have been possible without Lemon.

We’ve been working for ~1.5 year with one of their full stack engineer from Brazil, Matheus, whom we strongly recommend. As 2 co-founders looking for moving our prototype product to a production level, Lemon has been amazing at guiding us through the selection process and then ongoingly whenever we had any questions or requests (thank you Andrew Bondar) – definitely recommend.

It hasn’t happened to us before, but we promise to do it if needed.
