We partnered with Stubbs on a fintech project in the crypto space, where they supported us with blockchain development, Solidity smart contracts and backend work. The team joined the project very quickly and integrated smoothly with our internal developers. Their project management has been efficient and well-organized with clear communication and fast responses throughout the collaboration. We especially appreciated their strong expertise in blockchain and fintech, which allowed them to start contributing almost immediately.
