Kyran Janssen
Web and app development, and the automation behind it.
Based in Finland,
working worldwide.
What I do
Building for the web
Product sites, web apps, ecommerce, platforms built on a CMS. Next.js, TypeScript, React, Tailwind, Sanity. Design through deploy.
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
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.
Open to work, and to problems that are more interesting than they look.
