I'm Ian Welerson, a Frontend Engineer with over seven years of experience building modern, user-focused web applications and SaaS platforms.
I work mainly with JavaScript, TypeScript, Vue.js, Svelte, Next.js, HTML, CSS, and SASS, and I enjoy creating interfaces that are both reliable and easy to use. I also have solid experience with testing tools like Jest, Vitest, Cypress, and Playwright, and UI libraries such as Tailwind, Shadcn, and Chart.js. My focus is always on maintainable code, performance, and accessibility.
Beyond the frontend, I’ve worked with backend technologies including Node.js, NestJS, GraphQL, WebSockets, REST APIs, and Supabase. I’m also familiar with monorepo setups using Turborepo and scalable architecture patterns like Feature-Sliced Design (FSD).
In past roles, I’ve taken on Tech Lead and Head of Frontend responsibilities - helping guide technical direction, improve development workflows, and mentor teammates.
Over the years, I’ve had the opportunity to collaborate with teams from Brazil, the United States, and Australia, gaining valuable experience working across different cultures and time zones.
