Existing in-house projects include an email client that classifies and routes messages, a payment-arrangement tool and a secure filing system. Further opportunities include AI-assisted email responses and predictive analysis of payment behaviour, collection costs and next best actions. These insights could also support a web portal for clients.

Tech stack you will work with

The environment includes PHP, Python, C# and Next.js, alongside legacy systems. You should be comfortable working across technologies and learning what a project needs. The role also builds on experience with SQL databases, APIs and Git.
