Update: May 2022
I have been working as a software engineer since December 2016 with brakes, 4 years in total. During this time I was working professionally mainly on FrontEnd - I was dealing with projects written in clear JavaScript, Angular2+ and AngularJS.
Major projects I have been involved recently include:
- Shop Floor Management web application (organization and sequencing of production in order to improve efficiency and eliminate recurring mistakes);
- Telemetry web application for analysis and visualization of measurement and diagnostic data;
- Technical analysis (chart analysis) web application based on ChartIQ charting library;
- Orders processing web application for salespeople;
Other projects: WordPress integrations, layouts codings, WordPress, Joomla, Prestashop modifications.
Additionally, I had the opportunity to develop applications for my own use based on React, NodeJS, and .NET.
At the moment I am looking for a FrontEnd / FullStack Developer position - I am mainly interested in Angular. I would also welcome opportunities for professional development in Backend - NodeJS and/or .NET.
