About

I am a software engineer specializing in JavaScript with a strong passion for building user interfaces (UI) and user experiences (UX) for web applications. I am adaptable and framework-agnostic, proficient in React, Vue, and Svelte. With a deep understanding of frontend development, I have worked on numerous projects as a Senior Frontend Consultant since October 2019. My notable projects include developing new features and maintaining platforms for Spirable, creating a modular design system for PlusPlusMinus, and rebuilding software for ProData Consult. I have also led projects at LingoHub, where I used NuxtJS, StoryBlok, and TailwindCSS to redesign their site and migrate over 300 blog posts. My role at SamKnows involved maintaining and developing new features for their data visualization platform, as well as building and maintaining public projects. Prior to my consulting roles, I worked as a Frontend Developer at Bitbar from October 2016 to October 2017. At Bitbar, I was part of a large team focused on rewriting the UI and eliminating technical debt in their mobile application testing software. My contributions included significantly speeding up the frontend build process and transitioning the application to a Vue.js Single Page Application (SPA). I hold a Bachelor's degree in Computer Science from Opole University of Technology. My technical skills encompass a wide range of tools and frameworks, including JavaScript, HTML, CSS, REST APIs, GraphQL, and various CSS frameworks and bundlers. I am also proficient in asynchronous communication, Agile development processes, and have a strong interest in modern UI frameworks, JAM Stack, web3, UI/UX, and accessibility.

Employment history

Remote Senior Frontend Consultant, Spirable / PlusPlusMinus / ProData Consult / LingoHub October 2019 - CURRENT

Since I moved back from London I have been working as a senior frontend consultant on numerous projects.

Spirable – I was responsible for developing new features and maintaining their platform. As well as refactoring existing code to new standards. I’ve implemented Linting, Prettier and e2e testing with Cypress. Connected all to GitLab CI/CD tools.

PlusPlusMinus – I created a design system for a luxury hotel company in South Africa. The system was built with React and Storybook. It was modular so the client could create websites for every location they had. I was the only frontend developer on the team. Worked closely with a designer and backend developer to deliver the product.

ProData Consult – I was responsible for maintaining and rebuilding existing software that generates landing pages for several markets based on JSON files from inhouse CMS. We were using React, Redux, Storybook to build and maintain a design system for these landing pages. I introduced Lerna to manage our monorepo more efficiently.

LingoHub -I used NuxtJS to statically generate the site, StoryBlok as CMS, and TailwindCSS for layouts. I was the only developer in the project working along with a designer. The main issue I had was to move over 300 blog posts from the old site to StoryBlok, I wrote a Node script to help me with that.

Frontend Developer, SamKnows, London March 2018 - August 2019

I joined the frontend team where I was responsible for maintaining the codebase and developing new features of
ttps://samknows.one/, a data visualization platform about internet measurement all over the world. I was also responsible for building and maintaining public projects like https://www.measuringbroadbandcanada.com/ or the SamKnows website
https://samknows.com/ which I did with cooperation with a designer and content manager. I used Vue with SSR and Prismic for CMS.

Technologies used: HTML5, CSS3, JavaScript ES6, Vue, Node – Express, Vuex, Prismic, SASS, Rest API, i18n, a11y, Webpack, GIT, Bootstrap, JIRA, Slack, Sketch

Frontend Developer, Bitbar, Wrocław October 2016 - October 2017

I joined Bitbar to rewrite the UI and remove the technical debt of their software for testing mobile applications on real devices. It was written in CoffeeScript with jQuery. I have joined a large team (about 20 people) that was split into the frontend, backend, QA, and DevOps. We were using agile methodologies. My first achievement was speeding up the frontend build process. We were using Maven before and the build time was over 2min. I proposed using Gulp.js with caching. I managed to get build times under
100ms (depending on how big the change was). I introduced linting, which caught over 40k linting errors over the old codebase. Then we decided to move our app to Vue.js SPA, because it was light, fast and we could go it gradually, view by view.

Technologies used: HTML5, CSS3, JavaScript ES6, Vue, LESS/SASS, CoffeeScript, Bootstrap, jQuery, Gulp, JSON APIs, GIT, JIRA, Slack

Best back-end engineers I've ever worked with...​

“I interviewed about a dozen different firms. DevsData LLC is truly exceptional – their backend developers are some of the best I’ve ever worked with. I’ve worked with a lot of very well-qualified developers, locally in San Francisco, and remotely, so that is not a compliment I offer lightly. I appreciate their depth of knowledge and their ability to get things done quickly. “
