Cross-language contract testing with Pact + Broker

Cross-language contract testing project between a Python consumer and a Java/Spring Boot provider, using Pact Broker on Docker and PostgreSQL to publish and verify contracts. The workflow includes commit-based versioning, verification through the Broker and real gating with can-i-deploy in GitHub Actions to block deployments when breaking changes appear.

Playwright + TypeScript E2E automation

End-to-end automation project with Playwright and TypeScript that applies the Page Object Model on Sauce Demo, separates smoke and regression suites through tags, and keeps failure evidence with screenshots and traces. The project includes reproducible local and CI execution, a pull request workflow for smoke tests, and nightly publication of the HTML report on GitHub Pages.

Java microservice test harness

Java microservice with a REST API and real PostgreSQL persistence, designed to validate correctness, reproducibility and end-to-end testing under production-like conditions. The project manages the schema exclusively with Flyway, runs integration tests with RestAssured and Testcontainers, verifies idempotency and error cases, and applies quality gates in GitHub Actions with Spotless and JaCoCo.
