At Blue Flag I have been responsible for development of multiple products for various clients from the automotive industry. Including a learning management system for Toyota, Mitsubishi and Hyundai and an auditing system for Toyota and Hyundai. While here I have worked on migrating legacy platforms to serverless architecture, as well as maintaining existing code bases and building new applications. The platforms make extensive use of Amazon Web Services (AWS), with the client code hosted on CloudFront, backend services dockerized and hosted on ECS or Lambda and utilizing S3, DynamoDB, Cognito, EFS, SNS, SQS, Firehose, Athena and other AWS services. Data for these applications is stored in either MongoDB, PostgreSQL, S3 or DynamoDB.Our most modern project is a Learning Management System written with service oriented architecture principles in mind, it contains multiple sub services that communicate using GraphQL data stored in DynamoDB, and authentication for eLearning Modules achieved using Cloudfront and Lamda@Edge. Lambda triggers are used to handle events when data is added to S3 buckets, DynamoDB tables, SNS topics and SQS queues.

weComm was acquired by OpenText to adapt their Wave mobility platform for use in their enterprise suite.The Wave platform was developed to assist with writing cross platform applications for a variety of mobile platforms such as Android, iOS, Blackberry and Windows Phone, it has been used in many high profile projects such as CNN’s Turner Classic Movie app, CNN’s Election App and the AFL Club apps. The platform translates XML documents sent from an integration server to a custom protocol that is then sent to the client application, the lightweight protocol is designed to be resilient to adverse issues are typically associated with mobile data connections.While working at weComm/OpenText I primary developed the server side platform that’s written in a combination of C++, C# and Java (J2EE). The C++ and C# components communicate using OLE while the C++ and Java components utilize JMS. I worked extensively implementing features required to advance to server, including message compression using zlib as well as, HTTPS support and performance and security enhancements.Using profiling tools I identified performance bottlenecks within the server, caused by locks on C++ STL priority queues, I resolved this issue increasing throughput dramatically by removing locks and utilizing a concurrent priority queue.

While at Colour Vision Systems, I was responsible for developing products in C, C++ and also C#.I was responsible for bug fixing and feature addition for the Windows front-end for Colour Vision Systems’ flagship product, developed on Visual Studio 2003 in C++ and MFC. The system used XML for storing local data and an in-house protocol for communicating with the embedded machine. The front-end system was multi-threaded and utilized OLE for interprocess communication. I was also responsible for the implementation, design and documentation of a human machine interface touch screen for controlling fruit packing lines. This touch screen system was written in C# using Visual Studio 2008 and communicated with Omron PLCs using FinsGateway over TCP/IP.The touch screen system used XML serialization for storing the systems data.I also adapted an electronic real-time, multi-threaded vision system that was originally designed for grading fruit using a cup conveyor for use with lobsters on a belt conveyor. This project was achieved using C#, Matrox Image Libraries and Microsoft SQL Server 2008 for storing statistics.Paul developed a test application in C for testing the use of embedded processors for RF communications to fire solenoids. Also a GStreamer plugin written in C on Linux for video segmentation. Additionally, I wrote test implementations of a protocol for sending encoder pulses over Ethernet using C# UDP Sockets.I also assisted with the development of a C based application for video accusation from a gigabit Ethernet video camera on a Linux based platform. Responsibilities:• Customer Liaison.• Training Junior Staff.• Problem Analysis and Problem Solving.• Programming (C++, C#, C and PLC).• Bug Fixing.

Working at the IBM Customer Support Centre gave Paul the opportunity to work in a large team environment with the responsibility of training junior staff was able to resolve 96% of Victorian Police issues on first contact and was given the responsibility of training junior staff in the operation of the tools.This gave Paul experience liaising with clients and working in a large team environment.For Corporate Clients such as Toyota, McDonalds, Victorian Police, Australian Department of Heath and Sony
