My experience as a presenter

I have never presented at a conference before. However, I have quite a lot of experience in presenting at local meetups in Helsinki as well as at Tech Weeklies (https://techweeklies.futurice.com). This is why I think I’m ready to step up and present at a conference.

My presentations at Meetups:

Koodiklinikka meetup (2018-10-30) – Why you should be creating shitty useless side projects
HelsinkiJS (2019-02-21) – Lessons learned while creating onkometrorikki.fi

My presentations at Tech Weeklies:

Cycle.js basics – My experiences trying to learn it (2017-10-13)
Building LEGOs with React + MobX (a real client project :)) (2018-01-12)

Advanced SCSS

Or, 16 cool things you may not have known your stylesheets could do. I'd rather have kept it to a nice round number like 10, but they just kept coming. Sorry.

I've been using SCSS/SASS for most of my styling work since 2009, and I'm a huge fan of Compass (by the great @chriseppstein). It really helped many of us through the darkest cross-browser crap. Even though browsers are increasingly playing nice with CSS, another problem has become very topical: managing the complexity in stylesheets as our in-browser apps get larger and larger. SCSS is an indispensable tool for dealing with this.

This isn't an introduction to the language by a long shot; many things probably won't make sense unless you have some SCSS under your belt already. That said, if you're not yet comfy with the basics, check out the aweso
