Secure Scala Akka Developer
Generate secure Akka and Pekko actor systems and Akka HTTP routes with bounded mailboxes, supervision backoff, authenticateOAuth2 directives, cluster mTLS, and ask-pattern timeouts. Use when building typed actors, Akka HTTP routes, or clustered services.
Secure Scala Authentication and Cryptography Developer
Implement Scala authentication and JVM cryptography covering ES256 JWT validation, Argon2id password hashing, AES-256-GCM with fresh IVs, HMAC constant-time checks, and SecureRandom session tokens. Use when building login, session, JWT, or encryption code.
Secure Scala Core Security Developer
Generate secure Scala code using sealed traits, opaque and refined types, immutable case classes, and JSON decoders to block Java deserialization gadgets and SQL injection via library interpolators. Use when writing core Scala domain, validation, or serialization code.
Secure Scala Database Developer
Generate secure Scala database access with Slick, Doobie, and Quill using parameterized interpolators, auditing Fragment.const and infix escape hatches, HikariCP limits, and TLS-enforced credentials. Use when writing Slick, Doobie, or Quill queries.
Secure Scala Effect System Developer
Generate secure Cats Effect and ZIO code using Resource.make cleanup, Ref.modify atomicity, IO.uncancelable for audit or auth-critical sections, and typed error channels. Use when writing effect-system code handling resources, concurrency, or cancellation.
Secure Scala HTTP Client Developer
Implement secure outbound HTTP in Scala with Play WS and sttp clients covering SSRF allowlists, private-IP blocking, DNS-rebinding resolution, TLS pinning, and response size limits. Use when making outbound HTTP calls, webhooks, or federated fetches.
Secure Scala Play Framework Developer
Generate secure Play Framework 3 applications with AuthenticatedAction composition, strict parse.json body parsers, Reads validation, SecurityHeadersFilter CSP/HSTS, and production HttpErrorHandler. Use when building Play controllers, filters, or form handlers.
Secure Scala Streaming Developer
Generate secure Akka Streams, Pekko Streams, and fs2 pipelines with bounded buffers, idle and completion timeouts, backpressure OverflowStrategy.fail on audit paths, and authenticated WebSocket handshakes. Use when building streaming flows or WebSocket/SSE endpoints.
