• API-First Service with OpenAPI, a Generated SDK, and Contract Tests

  A REST API designed spec-first — the OpenAPI document is written before the code, the server validates requests against it, a client SDK is generated from it, and contract tests fail the build if the implementation ever drifts from the contract.

  Level: intermediate · Tools: React, Yjs, y-webrtc or Hocuspocus, SQLite-Wasm with OPFS

• Event-Driven Microservices with the Outbox Pattern and Distributed Tracing

  Three services that communicate through Kafka — orders, inventory, notifications — where every database write and its event are committed atomically through a transactional outbox, and a single trace follows one order across every hop so you can see exactly where time goes.

  Level: advanced · Tools: Go or Java, Kafka (Redpanda), PostgreSQL Outbox, Debezium
