Independent engineering work focused on test infrastructure, developer tools, and desktop applications.

• Designed a streaming test lab spanning web, Android, iOS, tvOS, and webOS, with Appium and Selenium Grid routing tests to containers, simulators, and remote hardware.
• Built a Rust CLI and Tauri desktop app that export repository context under configurable token budgets.
• Developed prototypes in options margin analysis, browser privacy testing, media tooling, and macOS compatibility automation.

Led QA for Integrations and Firm Management, owning test strategy and automation for partner data flows, access controls, and release validation.

• Owned Plaid API Integration QA; automated the release-validation suite across test, stage, and production sanity checks. Launch monitoring reported a 99.98% successful-sync rate in the first week.
• Reverse-engineered legacy integrations using Datadog traces and database queries, documenting the data flows and uncovering defects missed for over a year.
• Managed Kong Authentication, Bulk Data Export (12+ partners), and multiple inbound/outbound integrations.
• Supported the Selenium-to-Playwright migration and a full company rebrand while keeping UI automation green.

Built and maintained test automation for internal PlayStation Store systems covering asset ingestion, metadata, publishing, and subscriptions. Also coordinated offshore contributors and interviewed senior QA candidates.

• Sole QA for internal apps managing PS Store assets; automated multi-part uploads, video encoding, content publishing, and privacy checks.
• Re-architected the legacy CMS test framework during its XML-to-JSON REST migration; led a Kinesis-based async testing POC.
• Inherited a monolith of thousands of TestNG scripts and built the v2.0 framework that replaced it for active development.

• Built the system under test and the harness around it: a mock streaming service in five platform flavors (web player, Android, iOS, tvOS, webOS) driven by one cross-platform page-object layer.
• Adaptive-bitrate down-switch proven across DASH, HLS, and CMAF by shaping the network with Toxiproxy; QoE telemetry asserted through a Conviva-style contract.
• Capability-as-config device matrix dispatched to real hardware and emulators, containerized and orchestrated with Kubernetes and Argo.

• Wrote a dependency-free deployment lab around simulated sensor traffic, with real UDP and TCP flows, fault injection, and a modeled time-sync gate.
• Deployed the same services with systemd containers, a Compose rack running chrony and ptp4l, a cloud-init VM, and Ansible, with gated bring-up and release-manifest checks.
• Validated by a config-driven pytest suite that runs live system checks against the deployed rack, plus a Playwright UI suite in CI.

• Native desktop app and standalone CLI sharing one Rust scanning engine; configurable content budgets and automatic splitting use the cl100k_base encoding.
• Private alpha with 132 unit and integration tests in CI; no public installer or hosted demo yet.
