From blank repo to paying customer.

I build funnels, AI apps and automations for founders, and wire the tracking that proves they sell.

  1. UTMs and click IDs are captured on arrival.
  2. GA4 and the Meta Pixel fire through one GTM container.
  3. The form fires Lead once, with a shared event ID.
  4. The contact lands in GoHighLevel with its first-touch source.
  5. Delivery and nurture emails go out from beehiiv.
  6. The Stripe webhook sends Purchase server-side, with value.

One technical lead, start to finish.

I'm Eli, a lead developer for founders and their brands, working US hours from Pangasinan, Philippines. I write the code, wire the tracking and run the small team that ships it.

  • Plan first

    Every build starts as a written brief: decisions, risks and what done means.

  • Ship weekly

    Small, reviewed releases, with a Friday wrap-up of what moved.

  • Measure from day one

    Tracking ships with the first page, not after launch.
