Special Mention Projects

“NEW MDT Messaging and Integration Solution” for PrixCar (using ActiveMQ/Camel and AWS)

Development of the NEW Solution for MDT Messaging and Integration Mobility Solution – as an alternative for re-deployment of the “legacy” solution for the PrixCar ( https://www.prixcar.com.au - a joint venture between Toll Holdings and a 3rd party, resulting from a spinning off of the Toll AutoLogistics division away from Toll Holdings).

A redesign and re-engineering of the “legacy” status “MDT (Mobile Data Terminals) Mobility Solution” with the intent to replace the legacy and complicated “home-grown” messaging and integration subsystems with simpler and more standards-compliant FOSS (free and open-source) software components.

While device side technology was kept compatible at API level as exposed to the Business Logic Application, the device side message-queueing and communication stack has been enhanced with the option to use a different communication protocol and JMS-like communication mechanism (“NMS” – a .NET implementation of JMS) connecting on the server-side to a FOSS product providing the standards-based Message Queueing – Apache ActiveMQ, in its turn complemented by the Apache Camel EIP server for implementing further integration with Backend Systems.

The server-side components - ActiveMQ and Camel – have been deployed into AWS Cloud in Linux instances in EC2, and also using RDS (MySQL) for enabling Failover and DR and guaranteed and delivery (no loss of a single message) in a clustered (multiple nodes) setup of ActiveMQ sharing same DB endpoint (RDS with “Multi-AZ” redundancy and high availability in AWS).

Technologies: mobile device side: .NET CF, OpenNetCF, C#, C/C++, NMS/JMS, XML, server-side: Apache ActiveMQ, Apache Camel, Amazon AWS Cloud (EC2, ELB, CloudWatch, IAM, etc.), Amazon Linux instances, Cloud-managed relational database service (AWS RDS with “Multi-AZ” for MySQL), ActiveMQBrowser, HermesJMS, SoapUI, JMeter, jManage, jConsole

TollMobile iPhone native mobile app development

Successfully completed implementation (coding and testing), based on elaborate sophisticated UI/UX designs produced by a professional design agency being engaged for that project/initiative.

The app that was intended for public use by Toll customers for looking up and tracking the progress of delivery of their parcels by entering or scanning connote barcode. However, despite being code complete and “beta”-tested, it was not published in App Store due organizational and corporate complications and circumstance at the time – all outside of control of the development group. Later on, a decision was made to provide same functionality via a centrally hosted mobile-tuned web app rather than an App Store native iPhone app. So this native app then was used as a working “prototype” / reference model for re-implementing the same functionality in the web app.

Technologies: Objective-C, C/C++, Cocoa Framework, REST, JSON, iOS SDK/APIs, XCode, TestFlight

Became recognized de facto and then officially appointed as the competency leader (in internal engineering processes chart) for the following areas: • SQL, Databases, Data Modeling • Performance and Scalability • Multithreaded, Parallel, and Distributed Programming • Guidance through technical publications (books, magazines, web resources)

Have successfully carried out design and hands-on implementation, as well as subsequent ongoing maintenance and ‘ownership’, of several essential ManageSoft subsystems and modules, highlighted below:

“Network Discovery and Inventory”

Implemented Network Discovery and Inventory, using a commercially-licensed integration with the venerable industry-standard Nmap network TCP/IP scanning tool (http://insecure.org), as well as CIFS/SMB and SNMP protocols;

Also, in order to improve usability of the discovery tool, have developed a Windows GUI version of a Remote Execution Password Store Manager tool.

Technologies: C, C++, Win32 API, Nmap, TCP/IP, SNMP, CIFS/SMB, Windows Security, WinPcap, Ethereal, SolarWinds, ManageSoft’s proprietary core system-level C/C++ multi- threading and tracing libraries/APIs

“MBSA Tool”

A “factory”-operated Database Application for generating XML-based definitions of Microsoft Security Bulletins and Patch information for use by ManageSoft Security Manager product for performing Security Patch Management tasks and integration with various different versions of Microsoft Baseline Security Analyzer (MBSA) tool.

The “MBSA Tool” effectively performs merging of security and updates bulletins from Microsoft’s various different proprietary undocumented XML-schema based definitions used by MBSA 1.1, MBSA 2.0 and Microsoft Office Updates tools, and conversion of the merged and refined information into the ManageSoft proprietary XML-schema based format.

The application works by extracting, refining and loading into the database of the information from the various different Microsoft XML-schema files, applying the database-maintained refinement and cleanup rules, and then generating the uniform ManageSoft XML-schema format file from the data.

Technologies: Microsoft SQL Server (SQL, T-SQL), .NET/C#, XML, XPath

“ManageSoft Importing Framework”

A subsystem for importing (resolving) ManageSoft Inventory and Reporting data incoming as HTTP PUT requests of files of various ManageSoft specific XML-formats been frequently generated and sent to ManageSoft Administration Server by ManageSoft Distribution Servers and Agents.

The HTTP handler infrastructure had become the basis for all ManageSoft data importers. A plugin architecture was required to enable ongoing development of data importers as plugins and a subset of existing importers were identified as required rewrites as new plugins for the new releases.

The infrastructure was required to scale to support a corporate environment consisting of up to 100,000 targets (users and computers). This constituted improvements to performance and scale, as well as reliability and recoverability of critical ManageSoft data.

In order to achieve scalability requirements an internal fine-grained and flexibly controlled parallel task execution infrastructure has been developed as a foundation of this subsystem - involving multithreading, custom thread- pooling and concurrency control elements.

Technologies: Microsoft SQL Server (SQL, T-SQL), ASP.NET / IIS HTTP handlers, .NET/C#, C++, XML, .NET Multithreading, Windows Performance Counters

“Compliance Importer” module performance re-engineering

Achievements:

Successfully performed the above responsibilities. In particular, successfully carried out design, hands-on implementation and maintenance on a number of extremely challenging and high-profile projects, highlighted below.

“FootyTips.com.au” – design and hands-on implementation of a dynamically customizable, high-profile, large-scale, high-load and 24x7availability web application powering Australia’s top online football games tipping portals (e.g., footytips.com.au, tabtipping.com, yahoo.footytips.com.au, AFL.footytips.com.au, tipping.foxsports.news.com.au, nova100.footytips.com.au, heraldsunchampionsclub.com.au, footytipsbb.optusnet.com.au, tipstar.footytips.com.au, etc.) By mid-2004 the system enjoyed the popularity of having more than 480,000 registered users (330,000 active), counting across all customized affiliate portals. It was smoothly handling its regular load of about 1,200 simultaneous user sessions at a “click stream” rate of up to 2,400 page requests per minute - by evenly balancing the load across a clustered environment consisting of 5 application servers and 2 database servers. It was steadily generating about 12,000,000 “page impressions” per month during the games season.

"1i00.com" – design and hands-on implementation of a high-profile customizable web application that was powering Digital Asset Management, Image and Brand Management, Pre-Press and Design Artwork Workflow facilities for a range of Australian divisions of some of the world’s largest multinational companies (e.g., nestle.1i00.com, Image.Panasonic.com.au, Nintendo.1i00.com, Bayer.1i00.com, etc.). It was safekeeping master copies of more than 30,000 “digital asset” resources, making them available on-demand to 2,300 authorized registered users, according to their profiled access rights. The same engine is powering a publicly available Artwork Workflow and Approval service www.iApproveIT.com. Production environment: intelligent clustered environment consisting of 3 web/application servers and 2 database servers, providing load balancing and fail-over redundancy.

“Electronic Travel Resources” – design and hands-on implementation of a high-profile web application developed and operated for Australian division of Business Travel International (BTI Australia). It allowed the staff of BTI’s corporate customers to submit travel and accommodation request online via Internet and track the approval and processing status. This customizable engine was running travel request web-facilities for BTI’s three major high- profile customers in Australia: Hewlett Packard (hp.etr.bti.com.au), ERGON Energy (ergon.etr.bti.com.au ) and John Holland (jh.etr.bti.com.au), and is operating at a turnover factor of up to 1,000 travel requests being submitted and processed via the system each day, with a built-in potential to scale smoothly as the load increases.

Special Mention:

“discoverie.com.au” rescue project

It is a complex JSP/Java/J2EE online information system providing a paid subscription-based service to law firms (barristers, conveyors etc.) that allows online submission of enquiries into Victoria’s Land Registry system (LANDATA) and retrieval of results such as titles, plans, certificates, etc.

The system was not originally developed by INTERACT Pacific, but was inherited together with the client (Discoverie Pty Ltd) when the original developer company went out of business.

The system has been employing a rather proprietary yet sophisticated “N-tiered” architectural design, addressing scalability and availability issues (in a clearly “pre-EJB” fashion), comprised of various layers communicating via Java RMI and also performing remote request to LANDATA host via a proprietary protocol (invoking a Windows DLL written in C via a “wrapper” Java class using JNI).

Given the challenge of an absence of adequate (if any) documentation for this rather complex system, I have successfully carried the tasks of re-installation of the system in the new hosting environment, “reverse-engineering” the systems logic and code model (using an UML tool, TogetherSoft ControlCenter), and have been performing modification and enhancements of the system upon clients requests, along with the general maintenance of the source code and assuring production up-time.
