Logistics company needed to rebuild a huge monorepo-microfrontends legacy app. The challenge here was to integrate sections from legacy app into new app while it catches-up features-wise. The least “expensive” option was to use an iframe and develop a small communication protocol using postMessage.

Layoffs happened. Overnight we went from 4 frontend engineers to 2.

A team of 1 lead + 1 developer wasn't making much sense so each of us was integrated into backend teams to form mixed ones instead.

Backend <-> Frontend communication improved. Story slicing became vertical. Story points estimation is slightly more challenging, but we learned to live with it.

My most important achievements during this period are developer experience related:

• introducing more eslint rules and IDE automations to make our code more consistent
• migrating the whole project from CRA to Vite.js, which allowed us to finally move to latest React + Typescript versions and get rid of a ton of npm vulnerabilities. As a result we also cut in half the time it takes to run our CI/CD pipelines

The number of frontend developers eventually grew from 1 to 4 so the company decided to form a frontend team and make me it's "temporary" leader. It was going well enough so the search for an experienced frontend lead lost priority over time.

During this period my team implemented a major redesign of the whole app, built a number of custom components on top of MUI, integrated Storybook with Zeplin into the project, all while delivering new features in a SCRUM environment.

Rebuilding a 3 year old Angular app from scratch using React + Typescript. This was my first experience starting a greenfield project. At the time Create React App was still "cool" and actively maintained so that's what I used. Material-UI 5 for components and styling.

Fintech startup building a cashless payments mobile app. I was responsible for maintaining and adding features to a huge Angular 2 backoffice app. This was my first contact with TypeScript which I absolutely loved and will never go back to vanilla JavaScript. Besides that, I also:

• added features to company's landing page
• built hundreds of transactional email templates (MJML + gulp tasks)

Mainly frontend development with React, including state management (redux) and libraries for async tasks (redux-observable[RxJS]), among others.

The projects I worked on here included design and development of a REST api, advanced Slack integrations, also frontend programming and Chat Bot development using Google's api.ai. The technology stack included Meteor, React and Redux, among other JavaScript libraries and web apis.
