Where the tech actually helps

Product is translation — turning grid physics into a screen a property manager understands is the same craft as SideGuy's whole mission — making powerful systems human-usable. Different stack, same job.
Climate runs on software now — the energy transition is won in billing engines and dashboards as much as on rooftops. Respect from someone who builds the unglamorous-but-load-bearing layer too.
