ABOUT ME
Mobile Architect. Flutter. GCP/Firebase
Mobile Architect. Flutter. GCP/Firebase
I build mobile apps from scratch, with supporting backends based on GCP/Firebase. Currently, I focus on Dart and Flutter, but I also have over 14 years of experience in JavaScript, 2+ years of React Native, and experience with Node.JS, MongoDB, and Python.
A little background
I started to code when I was 6, worked with 30+ different programming languages, and built my own called ObjectPath available in Python and Javascript. I hold BSc in computer science. I've been building commercial software since 2004 and was CTO of two startups.

I am big fan of the new Javascript. It makes the language less hackish and more robust. Javascript reached Pythons' ease of use and capabilities without scarifying performance or tooling which is by far best in the world.

Since 2017 I switched completely to mobile apps, in 2018 to Flutter exclusively. I can still help with HTML/CSS, but I'm not up to date with current specs.

Asyncode Platform was an attempt to create a platform where anyone who knows basic HTML could build fully fledged web applications. Among other responsibilities, I developed extensions to HTML that made the language dynamic. To achieve that, I hacked nearly every aspect of a web browser. Think of it as Angular.JS without need to write in Javasctipt.
