An independent design & technology gathering
Sample event14 May 2027 / Rotterdam, NL
One day for people who make digital things. Talks, small rooms, and conversations you’ll still be having on the way home.
Eight sessions. Two rooms. A day to make your own.
A room for a different kind of day.
Harbor Hall / Rotterdam
The programme
A little design. A little code. Plenty to talk about. Find your sessions and leave some space between them.
All times are local to Rotterdam.
—
30 min / Main room
Everyone
Meet the themes of the day and find your route through the two rooms.
The Assembly hosts
Get to know the programme, the people around you, and the spaces for conversation and quiet breaks. There’s more than one way to spend this day.
—
60 min / Main room
Design
Make hierarchy, language and interaction express the same product idea.
Mara Velez
Mara walks through contrasting approaches to the same interface. See how small choices create a recognisable voice without making everyday tasks harder.
Meet the speaker—
60 min / Studio
Engineering
Decide what belongs inside a component and what belongs between components.
Dev Mehta
Follow a shared interaction across component boundaries: state ownership, keyboard behaviour, and the decisions that need to travel with the code.
Meet the speaker—
60 min / Main room
Design
Separate decisions that need evidence from the ones you can safely reverse.
Noa Laurent
Work through a product scenario using a practical decision record. Explore assumptions, missing evidence, and the moment to stop debating and test.
Meet the speaker—
60 min / Studio
Engineering
Document the decisions another team needs to extend your system.
Ada Okafor
Connect component examples, usage guidance and ownership notes into a small handoff package. Make space for exceptions and the changes you can’t predict yet.
Meet the speaker—
60 min / Main room
Design
Choose a prototype that answers one useful question before building more.
Jun Park
Compare sketches, interactive flows and browser prototypes. Find out what each can test, and where apparent fidelity can give a team false confidence.
Meet the speaker—
60 min / Studio
Engineering
Use real layout, input and accessibility constraints to improve the design.
Ines Rocha
Take an interface from a fixed composition into the browser. Work with growing content, narrow screens and focus order, and see what emerges during implementation.
Meet the speaker—
45 min / Main room
Everyone
Turn the day’s questions into a next step for your own work.
The Assembly hosts
Bring the themes from both rooms together. Share an unresolved question or a small experiment you want to take back to your team.
The people
People who care about the work, and the way we do it. Six perspectives on making things that matter to someone.
Mara explores how language, hierarchy and everyday interactions give digital products a distinct character. Her session makes those choices legible to a whole team.
Interface voice
Find their sessionDev works on the state and interaction patterns connecting reusable components. His focus is making behaviour understandable across design and engineering.
Component boundaries
Find their sessionNoa helps small teams turn uncertain questions into decisions they can explain and revisit. Their session asks when discussion needs a test or a clearer record.
Product decisions
Find their sessionAda connects component implementation with the guidance teams need to use it. She focuses on ownership and the decisions that often disappear during handoff.
Handoff
Find their sessionJun uses prototypes to investigate specific questions about flows and behaviour. Their work matches the prototype’s level of detail to the evidence a team needs.
Prototyping
Find their sessionInes explores visual ideas through working browser interfaces. She treats responsive layout, keyboard use and content variation as part of the design process.

The space between sessions is part of the point.
Harbor Hall / Rotterdam, Netherlands
The place
An old waterfront hall. Big windows, long tables, and enough room to find your people. A little away from the everyday.
Harbor Hall is a fictional venue for this sample event.
Good to know
People who design and build digital products. Independent makers, frontend engineers, designers and small teams are all in the right room.
Absolutely. Pick sessions from either track. The programme lists each room and gives you time to move between them.
We’ll flag the clash before changing your plan. Keep the session you already chose, or swap it for the new one.

This is a fictional sample event. A real event owner should provide verified information about step free access, seating, quiet space and travel before announcing the venue.
Your downloaded agenda is a personal plan, not an admission ticket. Assembly is a sample event. Real organisers can add their own ticket provider.
