I build things and then try to make them hold up under scrutiny — automated tests, clear documentation, and CI that actually runs.
Most of what I work on sits somewhere between backend services and test tooling: APIs, data-heavy dashboards, and the automation frameworks that keep them honest.
A production-minded API automation testing framework for order and payment workflows. Layered test suites (smoke / functional / contract / resilience / security), data-driven cases from YAML, JSON and Excel, idempotency-aware retry, secret redaction in logs, and architecture decision records documenting the why behind each choice.
