I'm an IT Field Network Technician based in Brooklyn.
I build computers and servers, install Arch Linux or whatever OS is needed, setup the databases and services, setup the public facing UI, and pick the environment that the project is deployed to. I used to go with Heroku but nowadays it's Vercel and Cloudflare.
I'm currently using Figma to produce SVG based designs, directly translatable to mobile apps or web apps.
As a Field Technician, I'm usually travelling to a client's location. I'll bring my own tools and equipment but if the load is too large, then I'll bring it in a box truck.
