Build and own MyySports’ backend: design high-performance APIs/GraphQL services, integrate internal and third-party tools, and debug production issues while working closely with frontend, data, and other teams.
""Integrate several internal and third-party tools as needed across the product spectrum to enhance backend capabilities""
Tech stack maturity
Mainstream Modern
The skill set centers on widely used contemporary backend technologies like Go, GraphQL, and Node.js, which fit a mainstream modern stack rather than legacy or cutting-edge cloud-native specialization.
