Rafael Aguiar, AI Automation Engineer

Hi, I'm Rafael. I work as a Senior AI Creator in Direct Response, making AI video for international VSLs and ads, and I write tools to automate the repetitive parts of that job.

I came from video editing. Most of what's here started as a way to stop doing the same task by hand.

Projects

Project What it does
Avatarize Windows app that turns a photo plus audio (or text) into a talking avatar video, using your own HeyGen account through their official MCP server.
LoopVideo Windows app that turns one image into a 2:30 talking loop for VSLs, with Kling and FFmpeg. It asks before spending credits.
Portfolio My site, rafaguiar-dev.github.io. Plain HTML, CSS and a canvas, no framework.

Personal project

A production pipeline for my own YouTube channel. From a topic, it writes the script, generates narration and visuals, and then either renders an MP4 or builds an editable CapCut project, which is where I finish the edit by hand. Python and self-hosted n8n, with a small FastAPI panel to run it. The target cost is about US$1 per video; narration is 88% of that, and rendering takes 58% of the time. The code is private.

Tools I use

  • Code: Python, FastAPI, JavaScript (Chrome extensions), FFmpeg, Whisper
  • Automation: n8n, Playwright, REST APIs, webhooks, MCP
  • AI: HeyGen, Kling, MiniMax, ElevenLabs, Magnific, Higgsfield, Claude

Em português

Oi, sou Rafael Aguiar. Trabalho como IA Creator Sênior em Direct Response, fazendo vídeo com IA para VSLs e anúncios do mercado internacional, e escrevo ferramentas para automatizar a parte repetitiva desse trabalho.

Vim da edição de vídeo. Quase tudo aqui começou como um jeito de parar de fazer a mesma tarefa à mão.

  • Avatarize: app para Windows que transforma foto + áudio (ou texto) em vídeo de avatar falando, usando a sua conta HeyGen.
  • LoopVideo: app para Windows que transforma uma imagem em um loop de fala de 2:30 para VSL.
  • Projeto pessoal: um pipeline para o meu canal no YouTube. A partir de um tema, ele escreve o roteiro, gera narração e imagens e monta o vídeo (MP4 ou projeto do CapCut, onde eu termino a edição à mão).
