Ecommerce Tracking Developer — Shopify, Meta CAPI, Google Tag Manager

I run a boutique paid media agency focused on Meta ads strategy and scaling for DTC and ecommerce brands. As my client roster grows I need a reliable technical specialist I can bring in on a project basis whenever a client needs tracking, attribution, or data infrastructure set up correctly. This is not a full time role. Think of it as being my go-to technical partner — I bring you in when the need arises, you deliver clean work fast, and we build a long term working relationship. What you will be doing: Meta Pixel setup and verification inside Meta Events Manager Conversions API (CAPI) implementation — server-side event matching Shopify and Meta integration — ensuring purchase, add to cart, initiate checkout, and other standard events fire correctly Google Analytics 4 setup and configuration for ecommerce brands Google Ads conversion tracking — purchase events, ROAS tracking Google Tag Manager setup and management UTM parameter frameworks — building clean, consistent UTM structures across paid channels Product catalog setup and troubleshooting inside Meta for dynamic ads Attribution QA — verifying data is flowing correctly between platforms and third party tools like Triple Whale Diagnosing and fixing tracking discrepancies or broken events Occasional audits of existing tracking setups to identify gaps What I am looking for: Deep hands-on experience with Meta Pixel, CAPI, and Meta Events Manager Strong Shopify expertise — you know how ecommerce tracking works end to end GA4 and Google Ads conversion tracking experience GTM proficiency Someone who can jump into a client account, assess what is broken or missing, and fix it cleanly without hand-holding Clear communicator — you can explain what you did and why in plain language so I can relay it to the client Fast turnaround — most setups need to happen quickly before ad campaigns launch Experience working with agencies or as a white-label technical resource is a big plus What this looks like in practice: I will reach out when a client needs something set up or fixed. You scope the work, give me a time and cost estimate, I approve, you deliver. Some months there may be multiple projects, some months none. I want someone reliable I can count on long term, not a one-off hire.
