AVR Chiptuning

One of my favourite projects! Sadly, the client disappeared right in the middle of the service’s frontend implementation, so the screenshots represent the work in progress.

But anyway here is the story.

David needed the car engines database to let the user select he want to tune. After research he found and bought the required DB. But because that DB was just a scraped raw data, there were a lot of corrupted data and of course it wasn’t logically structured. So the primary goal was to model the data and create a complex CSV data normalizer

After that done, the next goal was to create an API. Here I decided to use my favourites: Rack wrapped in tiny hanami-api, warden for token authentication and dry-rb gems collection. That way we’ve got a beautiful and testable code.

Next step was to create frontend part. And that was the first time I choose Elm as a frontend language, having some awesome experience with it in my learning sandboxes. Everything went smooth until in the middle of frontend work my client stopped responding :(

Anyway, I’d love to use Elm again someday, that was a joy to work with it!

Actually this project had my dream stack: parsers/normalizers, data modelling, APIs, lightweight stack and Elm for frontend. I’d only add TailwindCSS in that list for completeness.
