I started working long-term with RapidAnd, a company that builds tools for logistics, accounting, and other operational areas. Most of what I do involves building full-stack systems.
The core of the stack is React Native for the frontend, since many of the tools are mobile-first. The backend communication is done through tRPC, which keeps things type-safe and fast to iterate on. For database access, I use Prisma, which makes modeling and querying data straightforward and reliable.
