Yassir · SEFAR / Design systems · Cross-squad leadership

Build a shared language while products keep moving.

I led Product Design for Mobility and B2B, contributing to SEFAR with other design teams, engineering and brand. I directly owned iconography guidelines and contributed to colour and typography foundations.

The case in 30 secondsGo to decisions ↓

The problem

Products had different UI kits while the brand and markets were evolving.

The decision

Bring product needs into shared foundations, with explicit rules for what should remain local.

My contribution

Direct ownership of iconography guidelines; contributions to colour, typography and cross-squad alignment.

Yassir · SEFAR — Build a shared language while products keep moving.
01 / Context

One ecosystem, different product realities.

Rider, Driver, Delivery and B2B had grown independently, with different UI kits and local workarounds. A changing brand added another constraint. Decisions needed to hold across mobile and web, light and dark modes, languages and writing directions.

Evidence & scope

Scale describes the shared system’s scope, not products or markets delivered by me alone.

02 / Direct ownership

A 24 × 24 frame is not a visual rule.

Icons could share a frame but still feel unrelated in weight, padding and rhythm. I created guidelines for 16, 24 and 32px sizes: stroke width, live area, corner radius, optical alignment, filled and outline behaviour, states, naming and usage.

Original iconography material: equal frames do not guarantee equal visual weight.
03 / Shared foundations

Design tokens had to survive a rebrand and a change of script.

I contributed to colour and typography with Mobility and B2B needs in mind. Status colours had to remain meaningful in dense operational screens and dark mode. Arabic required attention to hierarchy, baseline and rhythm, beyond simply choosing a font with the right glyphs.

04 / Working across teams

Start with a product problem. Decide what should be shared.

Weekly component reviews, cross-squad workshops and design critiques brought real problems into the system. Engineering and brand reviews tested whether a pattern could hold beyond one screen. If it solved a local need only, it stayed local.

SEFAR: a shared system developed with design, engineering and brand.
05 / Learning

Consistency is a decision between teams before it becomes a component.

My contribution connected product delivery with shared rules: directly through iconography, and collaboratively through foundations and cross-squad reviews. The system gave teams a place to align while continuing to ship.

Evidence & scope

Collaborative project. No individual claim to the entire system, and no unverified speed or efficiency metric.
