  • We are integrating with OpenSea API - platform that enable other market places to start doing NFT sales
  • Competent mid level with very strong API integration experience, what happens when the API is unavailable? What happens when the data is wrong? What security considerations do you take?
  • Bonus points for Kotlin, Java Spring boot but can be any OOP
