AI-Powered Outreach Automation (n8n)

Built a workflow that turns outreach into a structured pipeline.

The system: • Pulls verified leads from Supabase • Uses AI to generate personalized emails • Sends outreach via Gmail • Monitors replies and analyzes sentiment • Routes responses automatically (book meeting, review, or archive) • Sends follow-ups if there’s no reply after 48 hours

Result: a fully automated pipeline that moves leads → conversations → booked meetings.

Designed for creators, agencies, and teams running outbound outreach at scale.

AI Padel Referee Platform This project presents a web platform for an AI-based refereeing system that automatically analyzes and adjudicates padel matches. The landing interface highlights key features such as ball tracking, real-time decisions, and multi-camera analysis. The analysis screen visualizes match processing using computer vision. The detection images show real-time tracking of players, ball movement, and court boundaries. Unlike traditional sports analytics that mainly record statistics, this project integrates automated refereeing and match analysis in a single interface. During development, challenges occurred with fast ball detection and multi-player tracking, solved using a multi-stage computer vision pipeline combining high-speed frame processing and object tracking.
