Tset

Tset is a SaaS platform that helps manufacturing companies understand, simulate and optimize product costs and CO₂ emissions across the entire product lifecycle. The product handles extremely dense data sets used by cost engineers, procurement teams and decision-makers — making clarity, speed and structure critical to its success.

My role focused on improving usability, reducing complexity and creating a scalable design foundation for a rapidly evolving product.

Design Audit

The first step was a comprehensive design audit of the existing product. I reviewed core user flows, components, layouts and interaction patterns to identify quick wins as well as deeper structural issues.

The audit revealed inconsistencies in navigation, spacing, typography and component behavior, along with areas where cognitive load was unnecessarily high. This phase helped define clear priorities and established a shared baseline for future design decisions.

Prototyping

We explored multiple prototypes to rethink how users navigate through large volumes of data. The goal was to improve orientation, reduce the number of clicks needed to reach relevant information and create clearer hierarchies within complex screens.

These prototypes were tested with actual cost engineers to understand real user behavior. The insights from these sessions helped validate assumptions, uncover friction points and refine navigation concepts, screen layouts and interaction patterns before committing to a final direction.

UI Design

The final design resulted in a clean, structured layout that makes very high data density manageable on both large and small screens. A new navigation pattern and clearly defined visual hierarchy guide users through complex flows and extensive data sets.

By structuring information deliberately and reducing visual noise, the interface enables users to scan, compare and act on data more efficiently — without sacrificing depth or precision.

Components

To support scalability, I designed and delivered a set of new core components, including inputs, navigable tables, unified modals and standardized number and formatting rules.

All components were added to a growing design system with clear usage guidelines. Developer handoff was supported through documentation, Storybook and continuous design QA, ensuring consistency between design and implementation.

Project Finder

A faster, more intuitive way for cost engineers to navigate existing projects, create new ones and access templates. It improves discoverability and supports project creation in a dedicated, less overwhelming environment.

Design First

During my time at Tset, we shifted from a primarily development-driven approach to a design-driven workflow. I worked closely with the existing design team to introduce regular user interviews and ensure dedicated time for design discovery before solutions were defined.

By establishing clearer design processes and structured handoffs, we created space to explore problems properly, align early with stakeholders and make more informed design decisions. This shift improved collaboration, increased consistency across the product and raised the overall quality of the user experience.
