I'm Nino, a UX Designer who builds bridges between users and products, design and development, humans and AI.
I specialize in creating accessible, user-centered experiences while exploring how large language models can enhance workflows. I also share what I learn as a speaker at tech conferences.

Concept, UX & Design
more Mercedes
From initial pitch to final launch, I supported Mercedes through a major redesign of their sales platform. My role spanned the entire process: wireframing, iterating through countless feedback rounds, fine-tuning concepts and collaborating closely with development throughout implementation.

Lufthansa - Voice AI Travel Assistant
​
Lufthansa wanted to push the boundaries of what modern LLMs
can do and gave us the freedom to explore.
​
The Challenge
Create a conversational AI travel assistant, "Elisa," integrated
directly into the Lufthansa app. Users should be able to interact
with Elisa through voice as naturally as talking to a travel agent.
Elisa's capabilities:
- Suggest destinations and provide travel inspiration
- Answer questions about cities and locations
- Navigate and give local tips
- Find and book flights
- Handle casual conversation
​
The interesting part? This wasn't about wireframes or visual design.
​
The Real Challenge
Since Elisa operates purely through voice, the UX work was all about prompt engineering and designing the conversation architecture to minimize hallucinations and ensure reliable, helpful responses.
​
We built:
- A robust code architecture integrating Lufthansa's existing APIs
- A layered prompt system to guide GPT-4's responses
- Conversation flows that feel natural while staying on task
​
The Result
Elisa was a hit. User testing in Lufthansa's UseLab confirmed what we hoped: the assistant felt intuitive, helpful, and reliable
.
Keep your eyes open Elisa might be coming to a Lufthansa app
near you soon!
More LLM-based (Voice) Assistants:
As each use case for LLMs is unique - depending on the workflow - so is each (voice) chat bot. Here are some other clients I supported with UX, UI & Prompt Engineering for LLM-based (voice) chat bots:
Tamschick: Hadi
Tamschick is a Berlin-based company and they work together with museums, cultural institutions and brands to create narrative experiences for international audiences.
For their "National Olympic Sports Museum" project in Dubai they wanted a voice chat bot - Hadi - that would guide visitors through the museum, create a custom exhibition tour and educate them on sports and nutrition.
Tamschick: Ghost
For their "Dreamverse" project the artists at Tamschick needed a voice based chat bot powered by a LLM. Ghost is meant to speak to users about their dreams, guide them through a tour of the dreamverse (a plane that only exists in the dream world) and help them process and understand their dreams and the deeper meaning behind them.
Wycomco: Jini
Wycomco are specialists in everything Mac maintenance. Their motto is "One man, one mouse, 5 minutes and the problem is gone".
Together we build Jini, a text-based, LLM-powered chat bot that Mac users can install on their machine. If users had a question regarding anything surrounding their Mac or general tech stuff they can chat with Jini, who would use Wycomcos data to create on-screen tutorials, guides and answer all their questions.
