Gustavo De Pieri

AI Automation Engineer

I build AI workflows that run themselves.

About

I'm Gustavo, 28, from southern Brazil. I'm an Automation Engineer at Ontop, a global payroll fintech operating in 150+ countries, where I own the entire automation and AI layer for Customer Success — from prompt design and n8n orchestration to full-stack dashboards and the AWS infrastructure they run on. I design it, build it, deploy it, and keep it running.

On the side, I shipped SafeTaggy, a security SaaS with an autonomous AI pentest agent, from zero to production as a solo founder using vibe coding.

I learned by building things, breaking them, and shipping them. Four years working in the US taught me how to communicate clearly across cultures. Everything else I picked up by doing the work.

Projects

  1. Autonomous AI pentest agent

    SafeTaggy

    My side project. I shipped a full SaaS from zero as a solo founder. It's an AI agent powered by Claude that runs 9 real security tools inside isolated Kali Linux containers with real-time streaming. Stripe billing, scheduled scans, Slack alerts, CI/CD API.

  2. Customer success dashboard

    Morpheus V2

    I built this from scratch for our CS team at Ontop. It pulls data from Salesforce, Redshift, Zendesk, and Google Sheets into one dashboard. 1,200+ clients, automated daily syncs, health scoring, feature adoption tracking. It replaced everything they were using before.

    • Supabase
    • Drizzle ORM
    • Redshift
    • Vercel
    • Recharts

    • Tailwind v4

  3. Multi-layer churn detection

    AI Risk Scoring System

    I built a four-layer system that catches churn risk before it's too late. Hourly triggers via n8n, monthly ML predictions on SageMaker, sentiment analysis with RoBERTa, and a weekly Slack digest. It updates Salesforce and alerts the team automatically.

    • Salesforce API
    • Slack API
    • AWS Lambda
    • Google Sheets API

  4. Product analytics for CS commissions

    Feature Adoption Tracking

    I built a system that tracks whether clients are actually using our platform features. CSMs teach clients, log it in the dashboard, and we measure if teaching led to real adoption. It's tied to 20% of their commission.

    • Next.js
    • Supabase
    • Redshift
    • Amplitude
    • Google Sheets API

  5. Natural language to SQL agent

    Query Generator

    An AI agent I built so the CS team can ask questions in plain English or Portuguese and get SQL queries for our Redshift data warehouse. 7 schemas, 300+ fields, 50+ verified queries ready to go. No SQL knowledge needed.

  6. Enterprise automation suite

    30+ n8n Workflows

    I own the entire automation layer at Ontop. 30+ production workflows on n8n connecting Salesforce, Zendesk, Slack, Google Sheets, Redshift, and AWS. Churn alerts, reactivation detection, client communication, risk scoring, everything runs on its own.

    • n8n
    • Salesforce API
    • Zendesk API
    • Slack API
    • Google Sheets API
    • AWS Lambda
    • Python
    • JavaScript

  7. AI account manager for 500+ clients

    WhatsApp AI Chatbot

    I built an AI chatbot on WhatsApp that acts as an account manager for our long-tail portfolio: ~500 smaller accounts. It sends proactive campaign messages, handles support routing, looks up client data in Salesforce in real-time, and flags hot leads to the sales team automatically.
