Every interface begins with a bigger product decision
Product designer in Amsterdam, the Netherlands
That is where Temi's work starts: shaping product direction, critical journeys and the systems behind them.
Across more than a decade, his experience spans growth, design systems, accessibility and AI-enabled experiences across a wide range of industries.
Areas of expertise
- Product direction: I tend to look beyond the interface to understand the people, behaviours, technology and business decisions shaping the experience.
- Critical journeys: The design challenge is not to hide that reality. It is to make the next right action visible.
- Design systems: A design system does not stay useful because it has more components. It stays useful because teams can apply it to real product decisions without losing speed, clarity, or judgment.
- Growth: The stronger version of growth work asks why people hesitate in the first place.
- Accessibility: The goal is not to make every conversation about compliance. The goal is to make the accessible path the default path.
- AI-enabled experiences: Built Design DNA, a privacy-first tool that extracts a website's design system into tokens, reports and AI-ready prompts.
Selected work
Selected projects where product direction, system decisions and interaction quality moved together.
- Ultra Design System: I led the design-system work that modernised a ten-year-old LMS without rebuilding it, reaching 87% of the pages across both LMS products within eight months.
- Flight search optimisation: The flight-card redesign I prioritised within a wider search-results programme, lifting desktop E-CVR, mobile E-CVR and baggage margin.
- One system, five brands: A themed design system for five travel brands, connecting semantic tokens, Figma modes, migration governance and accessibility. I helped build it, then led its colour modernisation.
- Travix Price Alerts: Account-free Price Alerts I designed for undecided flight shoppers, with early funnel evidence showing discovery as the real growth constraint.
About
I am interested in work that is useful, durable and grounded in how products are actually built. That means thinking beyond individual screens and paying attention to how decisions scale across teams, how systems stay coherent over time and how products remain usable as they grow.
I am most useful in environments where clarity matters, complexity is rising and design needs to hold together across multiple teams, workflows or product surfaces.
Playground
Small products, plugins and experiments I have built to make work a little clearer, faster or more useful.
- Airspace (Web app · Mac app): A live view of the aircraft overhead at any location you choose, drawn four different ways.
- Verity (Web app): A behavioural-preference assessment that turns four colour energies into practical tools for growth.
- Thanos (Chrome extension): A playful tab cleaner that restores balance by closing half of your open tabs with one snap.
- Design DNA (Web app · Chrome extension): A privacy-first tool that extracts a website's design system into tokens, reports and AI-ready prompts.
- GateCheck (Figma plugin): Align your concepts to your design system before they move further into delivery.
Writing
Recent notes on design systems, growth, accessibility and product work.
- When the Interface Starts Acting on Your Behalf
Agentic systems move the design problem from what a model can produce to what it is authorised to change. That makes delegated authority, not conversation, the thing being designed.
- The Design System Is Actually a Negotiation System
Components are the visible output. The harder work is deciding which decisions are shared, which stay local, and what evidence is required to move between the two.
- When a Product Constraint Becomes Part of the Interface
A technical constraint becomes an interface concern the moment it changes what someone can understand, trust or decide next. Infrastructure does not stay inside the architecture diagram.
- Designing for Reassurance Is Different From Designing for Usability
Usability answers whether a person can complete an action. Reassurance answers whether they feel certain enough to commit to it, and the two pull apart as decisions get more expensive.
