Senior Performance Marketing Specialist | Technica
I’m a Search Engine Marketing (SEM) specialist who focuses on the intersection of high-performance bidding and technical data accuracy. I’ve spent the last several years auditing and scaling Google Ads accounts, specifically focusing on moving away from manual "button-pushing" toward data-driven, automated growth.

I specialize in the "hard" side of digital marketing: fixing broken conversion paths, auditing PMax inefficiencies, and ensuring that every Google Click Identifier (GCLID) is correctly attributed. I don't provide "fluff" reports—I provide clean data and a lower Cost Per Acquisition (CPA).

What I bring to the table:
I’ve managed complex global campaigns across multiple regions, handling everything from brand cannibalization audits to full-scale account restructuring. My background is in the agency world, so I understand the need for speed, but I prioritize technical precision—especially when it comes to custom GTM triggers and resolving dataLayer errors that most marketers don't know how to touch.

Core Expertise:
• Google Ads Mastery: Expert-level management of Search, PMax, and Display. I specialize in transitioning accounts to "Maximize Conversions" while maintaining strict CPA targets.
• Advanced GTM Setup: Custom event tracking, iframe-embedded form solutions, and troubleshooting JSON parsing errors to ensure 100% data integrity.
• Performance Audits: Deep-dive analysis of account waste, bidding strategy efficiency, and regional performance (e.g., managing budget shifts for specific territories).
• Conversion Optimization: Bridging the gap between a click and a lead through technical troubleshooting and technical tracking foundations.

The Stack:
• Ads: Google Ads (Search/PMax/Shopping), Microsoft Ads.
• Analytics: Google Tag Manager (GTM), GA4, Looker Studio.
• Technical: GCLID Attribution, dataLayer implementation, Custom JavaScript Triggers.
I’m looking for long-term partnerships or high-impact technical projects where I can take full ownership of the SEM strategy and tracking infrastructure. If you want someone who treats your ad spend like their own and actually understands the code behind the tags, let’s connect
