Design Advisory

Where strategy
meets craft.

Many companies reach a point where their product grows faster than their design maturity. Features pile up, inconsistency creeps in, and teams lose sight of the user. That's where design advisory makes the difference.

I work with founders, product leads, and engineering teams to bridge the gap between business goals and design execution — helping companies build the right product the right way.

Whether you need a trusted thought partner, a design process overhaul, or a senior perspective on product decisions, I bring clarity, structure, and momentum to complex design challenges.

01

Creative and Product Direction

Strategic guidance on product vision, feature prioritisation, and design decisions that align with your business goals and user needs.
02

Design Process Audit

A structured review of your current workflows, team dynamics, and tooling — with actionable recommendations to increase design effectiveness.
03

Team Mentorship & Culture

Supporting designers and cross-functional teams in building a mature design culture — through 1:1 mentoring, critiques, and shared design principles.
AI Design

Designing for
the AI era.

AI-powered eCommerce UX

Design for AI product recommendations, smart search, personalised browsing, and conversational checkout — experiences where AI feels like a helpful assistant, not an algorithm.

UI and AI interface design

I use AI to generate live design previews, vibe-code interactive prototypes, and iterate on UI directions in real time — compressing weeks of back-and-forth into focused sessions where you see and feel the product before a single line of production code is written.

AI-accelerated research and UX/UI audits

AI-assisted transcription, thematic coding, and pattern extraction cuts qualitative analysis time by up to 80% — 6-week programmes delivered in 2 weeks. UX/UI audits deliver prioritised findings on usability, visual consistency, and interaction patterns with clear recommendations for improvement.

AI-powered design system docs

AI-generated component documentation reduces design system documentation effort by 70% — ship a complete system faster and keep it updated automatically.
Design Systems

Building the
language of product.

Foundations

Typography scales, colour tokens, spacing systems, and motion principles that scale across platforms.

Components

Documented, accessible UI components with clear usage guidelines and variant logic.

Patterns

Repeatable interaction and layout patterns that reduce decision-making overhead for product teams.

Governance

Workflows, contribution models, and change management processes to keep systems alive and evolving.

A design system is only as valuable as its adoption. I've led and contributed to design systems that teams actually want to use — because they were built with the people who use them, not just for them.

My approach connects design tokens to production code, aligns designers and engineers around a shared language, and builds governance models that make contribution easy and meaningful.

The most impactful work I've done — including Storefront UI, an open-source system with thousands of users — started not with a component library, but with a clear design philosophy and strong team alignment.

About me

Behind the work.

Marcin Baran

I'm in love with the design process.

Design, for me, has never been about pixels. It's about understanding what a business is trying to achieve, what a user actually needs, and finding the clarity in between.

Over 15 years I've worked across industries — from global fashion brands to open-source infrastructure — and the pattern I keep seeing is that the most impactful design work happens when there's real alignment between business goals, user insight, and engineering reality. That's the space I try to operate in.

Outside of work, I'm a father, husband and dog owner. I love Warhammer games, painting miniatures, riding my gravel bike, catching good live music and eating good food.

If you've made it this far down the page, I'd love to talk.
