Montherion Labs builds tools and services that check marketing tracking on online stores. • I built and maintain Tracklint, a Chrome DevTools panel for tracking QA, published on the Chrome Web Store in September 2026. It records GA4 and Meta Pixel requests, checks them against a CSV measurement plan and the page's consent signals, and exports an HTML/CSV QA report. An unreleased 0.3 build adds TikTok Pixel support and privacy alerts for potential email addresses, phone numbers and WhatsApp links in captured requests. It was submitted for Chrome Web Store review on October 29, 2026. • I run WooCommerce and WordPress test stores to reproduce common tracking failures and verify each fix before offering it as a service: a GA4 lead tag that did not fire in Google Tag Manager, form, phone and WhatsApp click tracking, and duplicate TikTok Pixel purchase requests without an event ID. • I deliver evidence-based findings: what the browser sent, what the plan expected, how to reproduce each issue and what remains unverified. Tools: GA4, Google Tag Manager, GTM4WP, Meta Pixel, TikTok Pixel, WooCommerce, WordPress, Contact Form 7 and Chrome DevTools. AI tools assist the work; findings are checked against browser evidence.
