Deliveryplannerapp / https://deliveryplannerapp.com
Based in Gijón, Asturias - Spain
It's a SaaS app to optimize your last mile delivery parcels routes. Also customers can track their parcel.
Implemented in Java + Spring Boot + JSF and the actual planner algorithm in Common Lisp. The JSF part communicates with Common Lisp using Protocol Buffers over TCP sockets. The Common Lisp implementation is SBCL.
At the moment I just finished the planning algorithm and I have yet to get the tracking UI done before releasing to the public.
Next project will be a roster planning app, another SaaS, done entirely in Common Lisp using this excellent Weblocks fork: https://github.com/40ants/weblocks
