Engineering · Products · Notes

I take systems apart and write about building products.

Now

package main

import "fmt"

func main() {
	building := "systems and onplate"
	writing := "Go, Kafka, and products"
	learning := "new tools"

	fmt.Println("building:", building)
	fmt.Println("writing:", writing)
	fmt.Println("learning:", learning)
}
