clean, filter, merge or extract data
display results directly in the browser

I focus on practical, lightweight and userfriendly solutions no unnecessary complexity, no heavy frameworks, just a clean tool that does exactly what you need.
This gig is ideal for small businesses, internal tools, automation tasks, research workflows or anyone who needs a custom dataprocessing solution on the web.
