    I 'm a web developer, mostly specialising in JavaScript. I have experience spanning both frontend, backend, CI and underlaying tooling and repo management. The emphasis of my work has been frontend, with, lately, working mostly on development infrastructure (monorepo management, bundling, CI and other tooling requirements). Experience across technologies: Frontent: - React has been my choice for a frontend library (with Next.js for SSR/SSG) until recently and am fairly knowledgable and experienced on the matter - I've recently been introduced to Svelte and Svelte-Kit which I really like and support - I've worked with a couple of CSS frameworks and have to say am very inclined to use TailwindCSS Backend: - I have mostly used Node.js for my backend needs, but am really a fan of Golang (which I haven't yet used in production environment) - I have some experience with Google cloud and Firestore for BaaS (and the underlaying ecosystem) Bundling/Testing/Tooling: - for bundling I've used Webpack (CRA templates + the pain of overriding them, as well as using my own "from-scratch" setup), lately I'm a big fan of Esbuild, but am using Vite for production projects (which utilises some ESBuild under the hood) - as for TDD, I have mostly used Jest + React Testing Library (for React) and Vitest + Svelte Testing Library (for Svelte) - I have average experience with Cypress for E2E testing of the apps - I like to organise all my production projects as monorepos for which I use Rush.js + pnpm and simply love the said technologies for organisation, scalability, maintainability and ease of use - TypeScript, ESLint and Prettier, I believe, should be the standard and not have to be mentioned at all, but still, I'll mention that I use both extensively and insist on doing so in any serious project CI/CD: - in CI I've used GitHub actions and haven't had a need to use anything else - for deployment, I've used Google Cloud and have a good understanding of Docker (with not as much experience in production) My approach is always driven by scalability, maintainability, clean and organised code with reduced redundancy and employed automation wherever possible.
