Developer of CEDA, a DBMS which uses a log structured store to achieve state of the art I/O performance while providing atomicity, crash recovery, hot standby and incremental backup. CEDA is the only DBMS in the world using Operational Transformation for replication, synchronisation, branching and merging of databases.

Perth, Australia

C++ computational geometry template library for an AWS cloud based spatiotemporal database to represent the ore body and stock piles of a mine site, using triangulated surfaces and compressed voxel images. Support for running physics simulations of dig, dump, doze, stack and drain events.

C++, Python and SQL software development in an agile team, for optimisation of the mining operation, particularly the dispatching of haul trucks.

Embedded development on front end ticketing devices in C/C++. Development of test infrastructure in Java and acceptance tests in FitNesse. Agile development.

Mentor for using CEDA in Mining Dynamics

Worked in a team on a C++ product called FracSIS using an ObjectStore OODB to record and display spatial data and meta-data, import and export many data formats, apply coordinate system transformations.Demonstrated advantages of CEDA over ObjectStore, such as transaction throughput, replication, branching and merging. Created Cedanet Pty Ltd and negotiated.

Worked on the Manchester and Singapore AFC systems.

Rome AFC system for ERG. Developed OCMS network and device monitoring system using SNMP.

Developed image processing applications for the Meat Research Corporation (Cattle light striping, the Portion Assessment System, Whole Carcase System and Chiller Assessment System), the Skeleton weed eradication system and the Hamersley Iron ore car inspection system.
