AI Product & Behavioral Experience Designer

I design how humans and AI make decisions together in complex products

I work with teams building AI products that need more than features: clarity on what AI decides, when humans intervene, and how to build real trust. I design behaviors, autonomy boundaries, and escalations before a single line of code is written.

Your AI works technically. But your users don't know how to use it.

You built AI features that work. But users don't understand what the system decides, when to intervene, or why it acts that way. Your team spends hours explaining behaviors. The result: low adoption, frustration, and ROI that never arrives. This isn't a technical problem. Nobody designed the system's behavior or how humans and AI work together. And that gets designed before you build.

Users don't know when to trust the system

Without clear autonomy boundaries, users don't know if they can delegate or must supervise. Result: systematic mistrust, micromanaging the AI, or outright abandonment of features that took months to build.

AI makes decisions it should escalate

Without clear escalation rules, the system decides in critical situations that require human judgment. Or the opposite: escalates everything and kills velocity. Balance doesn't exist because it was never designed.

Humans and agents don't communicate effectively

AI doesn't explain its decisions. Users don't know how to guide it. No feedback loops. The system doesn't learn from errors or improve with real use. It's static from day one.

Your architecture doesn't scale because design didn't plan for it

What worked for 100 users collapses at 10,000. The human-AI collaboration you informally designed can't handle complexity. Redesigning the entire experience costs more than designing it right from the start.

Experience and behavioral design for human-AI systems

A single design vision that defines how humans and AI make decisions, collaborate, and scale together—before code is written.

Human → AI experience design

how people understand, guide, and control the system

I define what people need to see, understand, and control when working with AI: clear autonomy boundaries, intervention points, feedback on system decisions. I design how users delegate, supervise, and trust across automation, assistance, and autonomy—with clarity from day one.

UX & Context Design

AI → human behavioral design

how AI decides, acts, communicates, and escalates

I define how AI agents behave: what decisions they make autonomously, when they escalate to humans, how they explain their actions, how they handle uncertainty and errors. I translate this into executable rules your technical team can implement without ambiguity—not PowerPoints, but real behavioral architecture.

One integrated vision. I design the complete experience in both directions: human→AI and AI→human, with clear boundaries, explicit control, and the ability to scale without redesigning.

Systems and platforms where I designed human-AI behavior

Cases where I designed how humans and AI make decisions together, defining autonomy boundaries, escalation rules, and behavioral architectures that enabled automation with control, scaling without chaos, and sustained trust. The result: organizations with less friction, greater clarity, and real capacity to evolve.

TÜV Nord - Sistema Cóndor

TÜV Nord - Cóndor System

Centralized system that reorganized audits, auditors, and certifications previously scattered across manual processes. I designed the system behavior and the experience between users and intelligent automation, defining autonomy boundaries, validation rules, and AI-assisted workflows. Result: 80% less administrative load and teams focused on higher-value work.

Arketify

Ministry of Security - Integrated Platform

Platform connecting citizens, internal operations, and document transfer across government agencies. Before: fragmented flows with no visibility or control. I designed the complete human-AI experience: what the system decides autonomously, when it requires human intervention, how decisions coordinate. Result: operations up to 10x more efficient and significantly improved system control.

Mi Caja - Ministerio de Seguridad

Arketify - SaaS Platform

SaaS platform for profile analysis and team formation. Starting from fragmented processes across multiple clients, I designed how users and AI agents collaborate: what analysis AI generates autonomously, when it requires human input, how trust is built in recommendations. Result: a platform that scales reliably with a clear and trustworthy experience.

"Our operations were spread across multiple systems with no clear flow. Lucas designed a system that unified everything and clearly defined how people and automation should interact. We're now 10x more efficient without growing the team, and with far better control."

Ready to design how humans and AI work together?

If you're building something with AI or your system needs to scale without redesigning, let's talk. I design human-AI behavior and experience before code is written—with clarity, control, and room to evolve.

Based in Buenos Aires, Argentina

I design human–AI experiences and intelligent system behavior for complex products. I work with teams that need clarity, control, and trust to scale with AI.
