From our cohorts
"REST API Design Foundations gave me a repeatable checklist for error envelopes. I still open the week-4 template before every release."
"GraphQL cohort was packed — mentor office hours saved my federation subgraph."
"API Security Hardening — mTLS lab finally made partner auth click. Rating honest: OAuth week felt rushed."
"B2B Integration Capstone webhook signing exercise — we reused it on our vendor portal. Client in retail ops."
Inclusions across programs
