About Antonio

Hey! I'm Antonio, an AI Engineer focused on business impact and specialized in automations, AI agents, and vertical AIs. My approach starts with problems and metrics: I map critical workflows, data sources, and constraints (security, compliance, SLAs) to design solutions that increase revenue, reduce cost per resolution, and shorten time-to-value. I build agents and automations that operate across multiple channels — app, email, Slack — with governance controls (RBAC, PII masking, human-in-the-loop) and telemetry to explain decisions and iterate safely — always prioritizing measurable business outcomes.

From a technical perspective, I deliver end-to-end solutions using Python, Google Cloud/Vertex AI, FastAPI, data pipelines, and RAG where it adds value. I implement containerization with Docker, CI/CD, and observability for latency, drift, and feature-level adoption, backed by comprehensive testing. I work from discovery to go-live, ensuring clear documentation, training the team, and providing actionable playbooks for ongoing operations and continuous improvement. The result: higher conversion rates (trial to paid), more predictable processes, simplified auditing, and a solid foundation to scale AI products with quality.

  • TrialPaid AI
    AI Engineer
    April 2025 - July 2025 (3 months)
    As the creator and developer of TrialPaid AI, I designed an agent that accelerates trial user activation in SaaS products. It reads users’ digital “body language” in real time, detects friction points, and triggers ultra-contextual nudges through the right channel (in-app, email, Slack/SMS/LinkedIn). The agent dynamically adapts tone and messaging based on the user’s current stage while logging every interaction for continuous learning — shortening time-to-value and guiding users toward their “aha moment.”

    On the back end, I built a production-grade automation in Python using CrewAI for multi-agent orchestration and FastAPI for stable integrations, exposing endpoints for user evaluation, cohort simulations, and notifications. The stack is fully containerized with Docker, including tests and quality checks. The system measures impact using key metrics like trial→paid conversion, reduced time-to-value, feature adoption, and retention rates, while integrating with analytics tools (for example, PostHog / Mixpanel) to close the insights loop.
