About

Hands-on engineer, architectural thinker.

Portrait of Pardeep Singh Basi

Pardeep Singh Basi

Loughborough, Leicestershire

Honest, determined and highly motivated full-stack TypeScript/JavaScript engineer with a strong focus on modern web technologies and real-world product delivery.

I’m driven by challenging problems and will keep iterating until there’s a robust, well-tested solution.

My core expertise spans real-time and API-driven applications (Node.js, Express/Fastify, WebSockets), modern front-end ecosystems (React, Next.js, Svelte/SvelteKit, Angular, GOV.UK Design System) and contemporary styling approaches (SCSS, CSS architecture, utility-first frameworks).

I’m comfortable working in cloud-native, containerised environments (Azure, AWS, GCP, Docker, Kubernetes) with modern build and tooling stacks (Vite/Webpack/Rspack, TypeScript, Jest, Vitest, Cypress, Playwright, CI/CD pipelines, Terraform).

I’m looking for cutting-edge projects that solve real problems, where I can contribute both hands-on and at an architectural level.
