At Orugbo Studio, I built one engine for seven white-label sizing and quote tools, including heat pump sizing for the UK and Ireland. The heat pump tool calculates heat loss using the BS EN 12831 method, then works out unit size, running costs, and the price after the grant.
For pdomhub.com, I built a sales site and solar sizing tool for a Lagos solar and inverter supplier. Customers can enter their appliances, usage hours, and region to get a system estimate; the result opens in WhatsApp, while the lead is submitted in the background. I came to building from selling, so I focus on tools that answer the questions buyers would otherwise need to phone about.
