Reckon Digital is a technology consultancy specialising in the creation of software for complex systems using a lean and agile approach. We assist organisations within the manufacturing industry, healthcare, culture, government, NGO, and academia with their digital challenges. Our expertise spans from experience design to back-end development, from operational research to data analysis and intelligent systems. We rely on a range of technologies and best-practices and we are particularly fond of the Python programming language, the Django web framework and the PostgreSQL database. Whenever given the choice, we privilege Free and Open Source Software ecosystems because of their advantages in terms of transparency, security, cost, and vendor-independence.
