Secure API & integration workAdam Zaghouani
Pitch: Need two systems to talk securely, or an API locked down properly? I build the integration and auth layer, the part that's easy to get subtly wrong.
You get:
REST API design/build (.NET, Spring Boot, or Node/NestJS) with proper auth
Third-party integrations: OAuth1/OAuth2 signing, payload encryption, webhooks
Auth servers (IdentityServer4 / JWT + TOTP/email-OTP MFA, LDAP/Active Directory)
mTLS, Liquibase-managed schema migrations, sandbox-validated before go-live
Ideal for: teams adding an integration or an auth layer they need done right, once;
