AI architecture and system design for government, enterprise operations, and platforms used by people every day.

The thread across all of them: trust as a system property — earned in how the architecture is decided, how context is managed, and how the AI reaches the user, not added on top of a working model.

Eunoia Care — AI Assistant for Caregivers

Families caring for a chronic patient live overwhelmed by fragmented medical information: lab tests, imaging, hospitalizations, instructions from different specialists. Forgetting and fragmentation are the main source of anxiety and care errors.

The problem

Designing an experience where a caregiver — often emotionally involved and without clinical training — could capture information without friction, in any format, and retrieve it when needed, in the format they need. Trust was the central design constraint: without it, the caregiver would never delegate to the system.

What I designed

The complete product architecture and a multi-agent system with distinct specialties (lab interpretation, longitudinal medical history, natural conversation), each with its own context, tone, and autonomy boundaries.

The caregiver captures information in any format — photo, text, audio — and the system converts it into a structured event. The AI responds with data, charts, or honestly signals when it doesn't have the information. I built a functional prototype with the agents running on the actual model, validating design decisions before implementation — especially each agent's boundaries and uncertainty handling in a medical context.

The design prioritized three axes: lowering capture friction, building trust through verification and honesty, and respecting the emotional weight of the context.

Outcomes

Significant reduction in caregiver cognitive load

Patient medical information available in seconds

Longitudinal medical history built through use, not as a separate task

Industrial B2B Support Tickets

Conceptual piece modeling how a B2B SaaS startup building support infrastructure for industrial machinery manufacturers could add AI to its ticketing platform — beyond a chatbot.

The problem

The real bottleneck wasn't ticket volume. It was what happened inside each ticket: incomplete descriptions, back-and-forth clarifications, technicians starting from scratch every time. AI couldn't solve this with a single generic system — different roles needed different interactions, and each role's trust threshold for acting on AI suggestions was different.

What I designed

Two agent systems with distinct identities — one for the operator under pressure, another for the expert technician — connected by a structured context object. Each suggestion includes an explicit confidence level and its source, so users can decide how much to trust each output. The system knows when to escalate and transfers the complete context to the human, without loss.

What the design demonstrates

Dual-agent architecture: separate identities for operator and technician, with structured context handoff

Explicit confidence levels in every suggestion, with traceable source

Human escalation patterns with no context loss

TÜV NORD Argentina · Sistema Cóndor

TÜV NORD operated with manual processes spread across multiple tools. Generating a commercial proposal took days of manual work and there was no centralized visibility of certifications or audits.

The problem

Internal users with very different expertise levels interacting with intelligent automation. The system had to decide when to act on its own and when to request human validation — without frustrating experts or abandoning less technical users. Trust had to scale with expertise, not be uniform across roles.

What I designed

The AI generates pre-proposals but always presents them as editable drafts — a design pattern that preserves user control without losing automation efficiency. Assisted flows show what the system did and why, so users can validate with context. Validation rules are configured by role, not by generic permissions.

Outcomes

80% reduction in administrative load

Teams focused on higher-value work

100% of operations centralized in a single platform

Mi Caja · Government Platform

Document and benefit management for retired personnel depended on in-person visits and manual coordination across agencies. Each process required physical travel, paperwork, and phone follow-up. Information didn't flow between areas, and no one had real visibility of each case.

The problem

Processes dependent on physical presence, manual coordination across agencies, and zero visibility of the real status of each case.

What I designed

A digital platform that centralizes processes and coordinates approval flows between agencies, with a web portal, mobile app, and complete inter-institutional workflow. Government-level security and traceability — the foundation I now build AI-native applications and platforms on top of.

Outcomes

70% reduction in processing times

Elimination of unnecessary in-person visits

100,000+ active users in production

Complete inter-institutional document traceability
