Essence Solusoft is a Ruby on Rails development company that has been shipping production software since 2016. From custom ecommerce portals and multi-vendor marketplaces to enterprise applications, MQTT simulators for tactical systems, AI-powered classification engines, and six live Shopify apps under the Essenify brand, the work spans industries and problem types.
