André Kallehauge is a product-minded software engineer with 11 years of experience building web and e-commerce systems, now focused on next-generation accounting and ERP at LedgerBee. He blends front-end polish and back-end pragmatism, having contributed to high-profile open-source projects like Automattic’s Calypso, Jetpack and ElasticPress where he worked on billing flows, product recommendations, and WooCommerce search integrations. Comfortable leading cross-functional efforts, he has held staff and lead roles at Automattic and run a boutique contracting practice delivering deep, client-focused work for organizations including UNICEF. He’s practiced at turning complex partner requirements into scalable APIs and partner integrations for large hosting providers. Based in Esbjerg, Denmark, André pairs a low-ego, shipping-first mindset with a knack for reducing friction in commerce and accounting workflows. An interesting quirk: he prefers taking one or two clients at a time to deeply own outcomes rather than juggling many engagements.
