  • A journey to functional JavaScript: Part 1 – fundamentals

    JavaScript has a quite fascinating history. Brendan Eich created on his own the first language prototype in just ten days. Its implementation was highly influenced by the concepts of first-class functions from Scheme and prototypes from Self. Initially, it was developed under the name Mocha, but released as LiveScript. The latter name didn’t last long either. Java was so hot back in 1995, that Netscape decided to…

  • Current state of Progressive Web Apps

    I have recently spent some time investigating the current state of Progressive Web Apps (PWA). Some of you may be wondering what hides behind yet another buzzword originally proposed by Google in 2015? This is an umbrella term for certain technologies that go together to produce an app-like experience on the web. This is how it is…

    In September of this year, I experienced my first exposure to the art of public speaking. I gave a talk at ReactJS Wrocław #7 meetup. I already published my presentation on my blog and you can find it here. I’m glad that I decided to share my lessons learned while working on the Calypso project. I’m satisfied with the topic I picked,…

  • Exploring functional JavaScript

    I started exploring functional programming (FP) concepts over a year ago. I have already shared my initial learning materials in one of the previous posts. It was only the beginning of my journey and today I would like to give you a much more detailed update on that topic. I picked the most interesting resources I discovered in the recent months.…

  • Dubrovnik, Croatia

    At Automattic we are encouraged to consider a team switch from time to time. Team switches help to bring fresh perspective to different projects the company is working on and provide opportunities to learn new skills. I decided to take advantage of this chance and joined team Amber in the middle of October. The timing could not be…

Sal is home to some of the best beaches in Cape Verde, and Santa Maria is where you’ll find clean white sands stretching off to the horizon in either direction. The island is…
