About

Paolo Cetti

// córdoba, ar

Systems Engineer (UCC) leading the technical team at Leanmote as Head of Engineering. I define the product's technical direction and scale the platform on AWS, balancing hands-on execution with team leadership. I joined Leanmote as a Full Stack Developer in November 2025 and took the Head of Engineering role in June 2026, during an internal transition of the technical team.

Before Leanmote, I built AI solutions at Pi Data (a WhatsApp bot for events with 300+ attendees, an LLM-powered email triage system used by government agencies), shipped scrapers across 10+ countries at Qanlex, and got my first formal dev job at Omixom while still in technical high school — migrating an agro-climate IoT platform to microservices.

I particularly enjoy when an architectural change becomes measurable — like migrating a critical PHP query that took 40 seconds to a Python Lambda that resolves it in 5–10s. I also integrate AI tools (Claude Code with subagents, git worktrees, custom skills) into my workflow as part of the craft, not as an extra.

Currently preparing for the AWS Solutions Architect Associate certification.

ZKP + AI Authentication

Zero Knowledge Proofs applied to biometric authentication via keystroke dynamics.

Research paper published at XI IDETEC 2024 (UTN Villa María, ISBN 978-987-8992-45-7). We trained a 9-layer Deep Neural Network on keystroke dynamics — pressed key, hold time, flight time — to authenticate users by their unique typing patterns, without storing the actual password.
