Joan Carreras

AI Native Performance Marketer

Your marketing team is drowning in manual work while competitors move 10x faster with AI. I fix that. I build the systems, run the campaigns, and automate the grind so your team can focus on strategy that actually moves revenue.

What I Actually Do

Joan Carreras

Identify

I audit your marketing stack and find the bottlenecks: manual reporting, repetitive tasks, broken attribution, wasted spend. No generic playbooks. A forensic look at what's actually slowing your team down.

Build

Custom AI agents, automated workflows, and data pipelines built for your specific problems. Python scripts, API integrations, HubSpot automations, whatever replaces the manual grind and makes your team 3x more productive.

Deploy

Ship campaigns and automations into production. Full-funnel paid media across Google, Meta, LinkedIn, TikTok with proper tracking, attribution, and real-time monitoring from day one.

Results

Real business results. Every system I build is measured against hard revenue metrics. Continuous feedback loops keep the agents improving.

Projects

SwingSurfer

A quantitative trading system I built from scratch. Backtesting engine, portfolio management, and AI agents that read trading books and autonomously replicate strategies. The kind of project that starts as a weekend idea and becomes an obsession.
