Position: Senior Front-End Developer
Category: JavaScript
English level: fluent
Years of experience: 6

1. I worked as a Frontend Engineer on a cloud platform for a German multinational automotive corporation. There I have optimized the overall build process for UI artifacts. Cleaned up build configuration, upgraded tools, and added a few utilities to improve the development experience. According to enterprise requirements adapted project so it could run in legacy browsers such as IE11 and MS Edge.

2. I worked on UI and server-side projects for a Swiss investment bank. While working there I had created major reporting application from scratch, prepared the main structure and library set to be used in the project. Introduced several tools to automate repetitive tasks, such as code style enforcement. Implemented a big part of the notification service REST API. This service significantly simplified the development of other applications and eliminated a lot of communication and planning across the teams.

3. I worked on an eCommerce platform with real-time auctions for a small retail startup. There I optimized UI of the project, reducing the bundle size significantly, which allowed the project to load much faster on mobile devices. Created a mobile application from scratch using React Native and helped with the other one. Both were successfully released to the Google Play and App Store in a short amount of time.

4. I worked as a web developer in an outsourcing company. While working on the network infrastructure load testing platform I implemented complex visualization of the testing setup (network nodes and networking hardware, interconnections, and test parameters) using SVG and Ember.js framework. For the other client I implemented a configuration script validator with a custom scripting language and integrated it to a web service written in Perl.
Technical skills: Modern JavaScript (ES6+), TypeScript, React.js, Redux, SASS/PostCSS/CSS Modules/Styled Components, WebGL, Web Socket, React Native, Expo, Webpack, Jest, Cypress.io. Have basic knowledge of DevOps (docker), intermediate knowledge of Node.js (REST APIs). Worked with MongoDB and several SQL databases.

Domain: I have the most experience in finances and e-commerce.

Soft skills: self-starter, great communication with clients and colleagues, have experience in mentoring, and public speaking.
I'm looking for a senior front-end developer position with React.js. Currently, I live in Kraków, Poland. Looking for relocation to Kyiv, Ukraine. 
I would like to work on complex user interfaces, preferably browser applications. Small team, startup, or product company oriented on the global market. The informal atmosphere and modern technology stack (with neat DevOps and tests) is a huge plus.

Also NO(!!!) Angular, ExtJS, PHP, and ASP.NET please. Thank you in advance.
