How I work

Part of the team. I join an existing team and help: I find where users struggle and the path that leads them there, agree which business goals and KPIs a task must move, and track them.

Research, both kinds. Interviews, user testing, outreach to people who dropped out and questionnaires, plus analytics I set up myself (Amplitude, GA4, GTM, Microsoft Clarity) to see drop-off by step. I agree the business KPI with the team before designing and check it after launch.

AI in my workflow. Claude Code and Figma Make for prototypes and real flows; I have designed AI features too (AIceberg).

Progressive web apps. I have also designed progressive web apps (installable, usable offline) for a document-signing product and a fintech product; both are under NDA.

Design systems

Design systems developers can build from

My role

Atoms, molecules, components
Every state covered
Tokens linked to Figma variables
Token-based handoff

I build design systems structured as atoms, molecules and larger reusable components used across the whole product. Every state is covered, tokens are linked to Figma variables, and the handoff structure is built on tokens, so developers know exactly what to use.

The Lysts design system: component variants, states and light/dark tokens

Close to engineers

I started in front-end, so I design with implementation in mind: I keep an eye on what makes developers' work easier, reuse components instead of inventing new ones, and keep the system cohesive.

At Cinnamon I built a design-to-dev handoff process with the tech leads that the agency adopted across projects.
