What I work with

A stack I know well

Tools I use every week, chosen for speed, stability and a good developer experience.

Front end

React, Next.js, TypeScript, Tailwind and accessible, well-tested components.

Back end

Node.js, Express, PostgreSQL and Redis, with clean APIs and sensible schemas.

Cloud and DevOps

AWS, Docker and CI/CD pipelines that deploy small changes safely and often.

Performance

Core Web Vitals, profiling and caching. I measure first, then make it faster.

Quality

Unit and end-to-end tests with Vitest and Cypress, plus code reviews that teach.

Design systems

Storybook libraries and tokens that keep a product consistent as it grows.

Selected work

Projects I am proud of

A mix of client work and side projects. Each one has a live demo, and most have the code on GitHub.

About me

Developer, teacher and tinkerer

I am Arjun, a full-stack developer based in Berlin. I like small teams, clear writing and software that is still pleasant to maintain in five years.

Outside work I mentor junior developers, maintain a few open-source libraries and cycle too far on weekends. If you have a product that needs building, I would love to hear about it.

  • 60+projects shipped
  • 12kGitHub stars
  • 40developers mentored

Kind words

What people say

Arjun rebuilt our checkout in six weeks and conversion went up 18%. He explained every decision and left the codebase better than he found it.

Sophie L.

Head of Product, Northwind Labs

The calmest developer I have worked with. He turns vague requests into clear plans and ships when he says he will.

Tom B.

CTO, Brightside

He mentored me through my first year as a developer. I would not be where I am without his code reviews.

Junior developer
