Kyran Janssen

Web and app development, and the automation behind it.
Netherlands, working worldwide.

What I do

01

Building for the web

Product sites, web apps, ecommerce, platforms built on a CMS. Next.js, TypeScript, React, Tailwind, Sanity. Design through deploy.

02

Automation and scraping

Large scale collection systems, structured enrichment, proxy infrastructure. Pipelines that run tens of thousands to millions of records cleanly. Python.

Selected work

Several of these live under Rainvalley, my solo software studio.

About

Based in the Netherlands. Four years owning the frontend across high traffic platforms, while building and shipping my own products on the side, from comparison engines to coordination software. I prefer software that lasts: built calmly, documented properly, no ceremony. Contact If you have something worth building, or worth automating, write.

Open to work, and to problems that are more interesting than they look. Email is best.
