Building the whole infrastructure: My task was to import about 9m datasets from public german sources, and put them into a PostgreSQL database, to be queried efficiently and without a huge latency.

Building the backend: Another task I had on my plate involved, that I am going to implement the backend. My tools of choice for this were tRPC for the internal API, Hono for the external API, and Next.js for the server-side rendering, and handling stuff that happens on the backend side of things.

Building the user interface: I have build the user interface, that you can see in the screenshots below. From selecting the perfect icon set, over finalizing the selection of a fitting font-face, to connecting the user interface with the backend.
