I’m Alexander, the person behind NullPointerCo.
I started the shop because developer wall art often falls into one of two camps: useful but visually uninspiring, or entertaining but not particularly useful. I wanted to create reference posters that developers could genuinely keep beside their desks while still looking good enough to hang on the wall.
Each design starts with a technical topic and a lot of editing. I collect the commands, syntax or shortcuts people regularly need, remove unnecessary detail, check the examples, and organise everything into a terminal-inspired layout. The aim is to make each poster easy to scan without losing the character of the tools and languages it represents.
AI is used as an assistant during parts of the research and development process. Every product is then curated, checked, rewritten, designed and prepared for sale by me. The finished digital posters are supplied as crisp vector PDFs in five common print ratios, while selected physical posters are produced to order by my production partner.
NullPointerCo is gradually growing beyond reference posters into terminal-inspired products for developers, including apparel, mugs and desk accessories. The same principle will run through everything: technically literate, thoughtfully designed and made for people who speak fluent terminal.
Thanks for visiting and supporting an independent shop while it grows.
