I am a uk-based independent builder and the founder of buildbyjai. i create practical web tools, calculators and interactive lead magnets for agencies and service businesses. my projects are built as functional, transferable digital assets with live demonstrations and clear commercial use cases. where applicable, a sale includes the source code, associated branding and documentation, along with reasonable handover support. i focus on simple products that a buyer can launch, customise, monetise or integrate into an existing business.
