Douglas Rapp is a Senior Software Engineer in Boston with 11 years of experience building high-throughput, distributed systems and mobile backends. He has a track record of designing end-to-end messaging and push infrastructures—from Android clients to Erlang/Scala services and Kubernetes deployments—while leading small teams and mentoring engineers. His work spans storage and syncing strategies (Cassandra, Postgres materialized views), real-time delivery (persistent Erlang connections, APNs/GCM), and auth systems (JWT, CSR-driven client certs). At Splunk and earlier at Layer, StackMob, and Adobe he focused on scalable, production-ready engineering and pragmatic tooling (CI/CD, Jenkins/Nexus). Colleagues rely on him for solving thorny system-level problems and for turning large-scale design constraints into maintainable implementations.
