Things I built, strongest first.

Ordered by what they demonstrate, not by when they happened. Each states an outcome rather than a description, and each opens into a write-up of what was built and what it taught.

Nine versions in production
CoTester
An agent that turns plain-English intent into executable tests, and repairs its own output before anyone sees it.
- Natural-language-to-execution pipeline
- Self-validation and auto-correction of generated steps
- Multi-tenant platform with cost and latency telemetry
- Read the case study
100+ labelled UI elements
Visual element recognition
Finds interface targets from pixels when the DOM offers nothing stable to anchor to.
- YOLO with transfer learning on a custom dataset
- Hand-labelled mobile UI element corpus
- Evaluated on mAP and IoU
- Read the case study
Pixel, OCR and LCS matching
Self-healing locators
Keeps a suite running when the interface moves underneath it, instead of failing the whole run.
- Pixel comparison and template matching
- OCR fallback for text-anchored targets
- Weighted LCS to re-anchor a moved locator
- Read the case study
Agent-driven cloud browsers
MCP server for TestGrid's device cloud
Lets Claude drive real cloud browsers on TestGrid, over a secure tunnel, instead of a scripted harness.
- Model Context Protocol server exposing device sessions
- Secure tunnelling to real cloud browsers
- Agent-initiated sessions rather than fixed scripts
- Read the case study
