& Automation

I connect paid ads, the sales pipeline and AI into one stable system. Without that link between channels, data gets lost, leads slip through and budget is spent with no visible result. All of it runs as one automated flow that I manage on my own.

Why a system

Dimension
Manual processes
Automated system
Lead tracking
✕Typed into a spreadsheet by hand, easy to lose
✓The CRM receives the lead, classifies it and opens a deal automatically
Follow-up
✕With manual follow-up, a deal only moves when someone sits down and remembers it
✓Instead of the one follow-up everyone sends, the system sends three: in the first week, in the second and at the end of the period, each with a different reason to reply
Answering inquiries
✕Writing every quote by hand, one to two hours each
✓The system writes and sends the quote. A review is requested only if you set a rule for it, otherwise there is nothing to do
Tracking & data
✕No way to know which ad brings in real customers
✓Conversion tracking that does not depend on the customer’s browser. Events are recorded on the server and sent straight to the platform.
Scalability
✕More customers = proportionally more hours of work
✓The system does the same work for 5 or 50 leads a week
Reacting to change
✕Problems surface only after a deal is lost or the budget is spent
✓The system recognizes when a deal stalls or when an inquiry needs an urgent response, and raises an alert right away.
Tools
✕Pays for n8n, HubSpot and OpenAI separately
✓A lead comes in and the system reacts. Each tool notifies the next one automatically. No copying data between tools by hand.

What I do

Paid Media

Paid campaigns with the right technical foundation: conversion tracking, server-side events, attribution modeling. Campaigns that can be measured, not just launched.

Marketing Automation

CRM integrations, email sequences, inbox automation and AI agents. I build systems that run autonomously from the first contact through the entire pipeline, whatever the outcome.

AI production

AI-generated photos and videos for posts and ads, with automated processing and format adaptation for every platform. Creative that goes live faster than a designer replies to a message.

Stages without coverage
Every step of the sales cycle is covered: automatic handling of new inquiries, CRM integration, quote generation, follow-up sequences after every stage, detection of stalled deals with an automatic nudge to restart them, and long-term nurturing for won and lost contacts. Every pipeline stage has its own automated flow, so no contact is lost, wherever it is in the process. The system runs on its own, without supervision, for the long term.

AI Creative · Paid Media

AI Video Creative Pipeline

AI-generated image and video creative for paid social and organic posts.

The entire creative pipeline in one person

From one photo: 3 AI videos × 3 formats = 9 finished creatives. The pipeline is automated from generation to upload.

Why signal quality is not a detail: Without server-side deduplication, Meta receives the browser event and the server event as two separate signals. Conversions can be counted up to ~2×, the algorithm learns from wrong data and CPL rises. The Regge system runs event_id matching, which makes sure every event is counted once regardless of the delivery channel.

Growth Intelligence System

A personal initiative, built instead of sending CVs to job boards. A structured pipeline that does what a mass blast cannot.

250+ verified contacts — the Zagreb tech and marketing scene, 8 data sources

A research pipeline that uses Claude Code to scrape and research public sources (LinkedIn, Clutch, job portals, the business registry) without a dedicated paid tool. Every contact is scored on email format, active hiring signal and priority. The pipeline is designed to plug into Apollo.io / RocketReach for further enrichment.

About me

Dominik Petrac

Campaigns are the starting point. Behind every one of them is a system of 20+ automations that take over the inquiry from the first click, send the quote, classify the reply and track where every lead is in the process — without a single manual step.

It is not about a single tool. I build the whole stack — from paid ads and conversion tracking to cold outreach and AI creative.

I care less about clicks and impressions than about whether the whole system delivered a result. I am looking for a team that works on serious and varied projects — I bring proven systems that can be applied to your business right away.
