Beautiful authentication: Tear down the barbed wire

ux & design

People don’t ever specifically want to sign in or create an account – they just want the features that being signed in allows. Somewhere between upselling and onboarding, they will run into the wall around your beautiful garden, and be forced to sign in if they want to get inside. I’ll review the ways you can make sure your gated garden isn’t covered in barbed wire. Although this talk will be focused on authentication experiences, the ideas apply to many other kinds of features. I will be using authentication, and in particular my experience with it at SoundCloud, as a case study

What is "Good"?: Exploring Design, Impact and Quality

Premature Product Portfolio: How could launching too many & too early not be insane for a startup?


“Focus, focus, focus!” is sound startup advice you’ve probably read from more than one Medium post. In reality, starting up with a huge vision and crawling through the idea maze to find a market fit for your early product experiments, how do you actually keep that focus? Should you mash every new experiment as a feature in your ever bloating MVP, or isolate experiments for cleaner testing results? Could a portfolio of small “products” help you or hurt you in marketing? I’ll walk you through our learnings from building a dozen location optimization products at Teleport, still in seed stage.

RxJS - destroy the state machine!

front end

Learn our story how we discovered RxJS, how it helped to bring SaleMove from a massive state machine into an elegant event-based reactive platform. We started out with a big state machine that was difficult to maintain, test and develop. As the application grew we quickly saw that another approach was needed. After discovering RxJS, we quickly adopted the event-based reactive approach.
In this talk I am going to give you an overview of RxJS and why should you use it. I am going to talk about how once we adopted the event-based approach, it completely changed the way we think about state and state programming. All this with code examples.

Design without designers

ux & design

Design is way more important to be only left to people who call themselves designers. Today design still misses to create the bigger impact it is capable of, mainly because designers have made everyone believe that design is a very specialised field that only they can do. But what happens when we believe everyone can be a designer and let anyone be involved in the design process? Let’s look into cases where we as designers left design to the others and let’s share some stories about teaching design to non-designers. The goal with this talk is to inspire anyone from developers to marketing and management teams to approach things like designers!

What drives a geospatial product evolution and what does it mean

At the same time, we provided users with an accessible editor for creating maps on the web.
