Visual

Visuals as structure, not ornament. work to articulate brand, guide interfaces, and create consistent visual languages.

VIBE CODE-BASED SMARTWATCH

I continuously explore new ways of designing and integrating AI into my workflow. Recently, I’ve been experimenting with Google AI Studio to create a smartwatch interface, and its potential is remarkable. Starting from an initial design, on-screen annotations allow for fluid iteration, making the refinement process feel far more natural.

I believe tools like this should be a must for designers, especially as a space for experimentation. To complement the process, I generated additional visuals using Flux and later animated them in Kling, bringing everything together in the final reel.

NEXLABS

This conceptual project foR NEXLABS explores the elevation of industrial cutting machines through a refined visual and narrative language. Using generative AI as a creative tool, the project reimagines how industrial technology can be perceived, moving beyond pure functionality to express precision, sophistication, and intention.

The visual system extends from imagery to identity, including a logo inspired by the laser’s fusion point; the exact moment where energy, material, and transformation converge. Through this approach, industrial machinery is reframed as a symbol of controlled power and technical elegance, bridging engineering and visual culture.

MU Pocket

MU Pocket is a conceptual exploration of a digital wallet designed around movement, access, and everyday mobility. The project rethinks transport and card management as a single, unified experience, where clarity and immediacy replace fragmentation.

The interface prioritizes hierarchy, legibility, and calm interactions, reducing friction in moments that demand speed and certainty. More than a functional tool, MU Pocket explores how a restrained visual language and a system-led approach can turn routine actions into a coherent, trustworthy experience.

DESIGN SYSTEMS & UI

DESIGN SYSTEMS & UI

Systems and interfaces designed to scale. Work focused on structure, consistency, and visual clarity, shaping UI languages that support complex products over time.

SULION

This project explored how a clear visual system can express a brand rooted in engineering, materiality, and control. The work focused on defining UI, graphic language, and design system foundations that translate Sulion’s product precision into a calm, structured digital experience.

the interface is built around hierarchy, rhythm, and restraint, allowing the product to speak through clarity and proportion. The resulting system establishes a durable visual base, designed to scale over time while preserving the brand’s character and visual coherence.

SIMON ELECTRIC

From June to September 2023, I worked on the redesign of simone electric and in the creation of its design system. The project focused on improving the digital experience for both B2C and B2B users, while establishing a unified foundation shared witH SIMON PRO, the brand’s B2B platform for distributors. An initial working session in Barcelona with key stakeholders helped align objectives, define priorities, and set a clear roadmap for the project.

My role centered on translating Simon’s brand values into a scalable digital system, balancing clarity, consistency, and visual expression. The design system was conceived as a long-term tool, supporting multiple products while ensuring coherence across interfaces. Built through close collaboration between design and development, the final result delivers a more intuitive, robust, and future-ready digital experience aligned with both user needs and business goals.

CRO & DATA DRIVEN DESIGN

CRO & DATA DRIVEN DESIGN

Design informed by behavior and data. Projects centered on optimization and experimentation, translating insights into clearer flows, better decisions, and measurable impact in business kpis.

SANTANDER OPEN ACADEMY

Over 2024 and 2025, I worked with Santander Open Academy on a continuous CRO initiative aimed at improving acquisition, activation, and overall user satisfaction across a platform used by millions of learners worldwide. Through data-informed iteration and close collaboration with product and development teams, we refined key funnel moments and evolved the design system to respond to real user behavior. The result was a more coherent, efficient experience that reduced friction in critical journeys, increased user activity, and contributed to a measurable improvement in NPS, reinforcing the platform’s role as a scalable global education product.

SANTANDER X

DURING 2024, I collaborated on the redesign of Santander X, focusing on strengthening the platform’s foundations through the evolution of its design system. The project combined qualitative user interviews with product insights to better understand motivations, friction points, and expectations across key journeys. This research-informed approach allowed us to refine interfaces, improve consistency, and create a more scalable system capable of supporting growth, acquisition, and long-term engagement. The result was a clearer, more cohesive product experience designed to serve both users and business objectives at scale.

BARCELÓ HR

I collaborated witH BARCELÓ CRO initiatives aimed at improving conversion and revenue by addressing key user pain points in the booking flow. One of the most impactful projects focused on redesigning the room selection step, simplifying decision-making and aligning the interface more closely with user expectations. By reducing complexity, clarifying actions, and restructuring how rooms and prices were presented, the experience became faster, clearer, and more intuitive.

The redesign had a direct impact on business outcomes, driving a significant uplift in revenue and improving user satisfaction, reflected in a strong NPS increase. The project balanced usability improvements with technical constraints, requiring close collaboration between design and development to ensure real-time pricing accuracy while maintaining performance and scalability.

GENAI

GENAI

A collection of AI-driven visuals developed as a space for exploration, where new aesthetics, narratives, and modes of image-making emerge at the intersection of design, technology, and visual culture.

WOVEN IDENTITIES

exploring Romanian carpets as symbols of cultural identity and collective memory. During my time living in Romania, I realized that many of these pieces, though deeply recognizable, carry no name: they exist, yet their authorship dissolves into tradition. This anonymity; almost always female, led me to imagine new characters dressed in these carpets as if in their own skin, their own history. By turning the carpets into garments, I aim to give them body, presence, and voice. They don’t represent any one person, but all the invisible hands that, for generations, have woven identity in silence.

NIKE ACG

This visual imagines the Nike ACG Lunar Lake puffer as a product born from impact in the moon. A meteorite strikes the moon, freezing the surface in an instant. From the crater, the garment emerges; not designed, but revealed and shaped by pressure, cold, and force. An ACG astronaut is dispatched to retrieve it, treating the jacket as both artifact and equipment. The piece frames outer space as an extreme testing ground, where performance, protection, and material intelligence are forged under non human conditions. For the best experience, watch in full-screen with sound on.

EMBODIED INTERFACES

These visuals belong to a series exploring how future interfaces may merge seamlessly with the human body. Each image focuses on a different sense, imagining how technology could evolve beyond external devices and become integrated into the user.

The first visual explores sonic interfaces, merging the familiarity of an ear piercing with advanced audio engineering. The ear becomes an active sonic interface, capable of transmitting, receiving, and processing commands, not just for listening, but for interaction, decision-making, and action.

The second visual imagines the next evolution of visual interfaces. A contact lens inscribed with circuitry suggests a progression beyond VR headsets and external glasses, where immersive displays contract into a transparent surface resting directly on the eye. Vision itself becomes both screen and interface, intimate, invisible, and immediate.
