Delphi Portfolio

May 2009

[ CV/Resume ] [ C# Portfolio ] [ Delphi Portfolio ] [ Microsoft SQL Server Portfolio ]

This section of my portfolio contains information about various Delphi projects I have worked on.  Certain technical information, code extracts and screen shots may be included.

BlueSteel

Manufacturing Production Software

• Database:
  • Microsoft SQL Server 2000 - 2005.
• Development Tool/s:
  • Delphi 7 - 2007.
  • Developer Express VCL Components.
  • Digital Metaphors Report Builder.
• User/s:
  • 60+.

This has been the main software development project that I have been involved in.  I have been involved in the directorship of Laser Junction over the past 8 years, but involved in developing the production software for 9 years.  The project started as a small quoting system based on a Paradox database and has grown into a full blown quoting, production and invoicing system, with numerous other functions to aid in the efficient running on the business running on Microsoft SQL Server.

My involvement in the project has been from Analyst to Developer to Tester and is now a project that is maintained by a small development team run by myself.  The team is continuing with the next version (V4) of the project which is being re-written in C#.

Production	DXF Checker	NestLink

Applications Developed That Run Alongside BlueSteel

• DXFChecker - Checks AutoCAD DXF files for open contours.
• BlueDox - Quality Control monitoring system.
• NestLink - Integration of Laser Cutting Production to BlueSteel Production.
• Numerous other miscellaneous applications.

What I Got Out Of It

• This project has been extremely satisfying for me as I have been involved since it's inception and I get to see users utilising the software every day.  It has added tremendous value to the company which started with a written order system. 
• My business analyst and management skills have grown tremendously over the years being involved in this project.

cazProcs

Delphi Reusable Routines and VCL Components

• Database:
  • N/A.
• Development Tool:
  • Delphi 1 - 2007.
• User/s:
  • Delphi Developers.

This is a reusable set of routines that I have developed over the years.  Some of the routines in this library have been included in the JCL (JEDI Code Library) project.

What I Got Out of It

• Reusable code that I have used in every Delphi application I have worked on.
• Acknowledgement within an international project.
• Reusable VCL components.

Security Alert Logging System

Integration of Logging into an Existing Security Alert System

• Database:
  • Microsoft SQL Server 6 - 7.
• Development Tool:
  • Delphi 5.
• User/s:
  • Corporate Water Utilities.

This system was an add-on to an existing alert system.  Using Windows NT Event Logs information was assessed and processed into a Microsoft SQL Server Database.

What I Got Out of It

• Exposure to corporate development meetings.
• Exposure to development using NT Event Logs.

Statistical Sales Reporting System

Reporting System

• Database:
  • Interbase.
• Development Tool:
  • Delphi 3.
• User/s:
  • 1.

System imported large amounts of data from other systems, compiled the data and reported on statistical information.

What I Got Out of It

• Exposure to Interbase Database.
• Gained tremendous appreciation for a clearly defined and specified project.  This project was not such a project, it was poorly specified which resulted in numerous misunderstandings and delays.

DebtCollector

Debt Collection System

• Database:
  • Paradox.
• Development Tool:
  • Delphi 1.
  • Nevrona ReportPrinter Pro.
  • Wise Installation.
• User/s:
  • Single user system sold commercially.

This is a very old system written in Delphi 1 (16 bit).  The reason I have included it in this portfolio is because it was a product that was release commercially, which opens up an entire different dimensions to software development.

DebtCollector is a software product to assist companies in collecting outstanding money from their debtors/customers.

Screen Shots

What I Got Out of It

• The satisfaction of developing a commercial project.
• Exposure to writing help files.
• Exposure to creating installation programs.
• I enjoyed the project immensely. Having to think outside the box and thinking of every possibility that could happen with software running on many different PCs and the impact that a single change would have on a user base.  The impact of support incidents if the application wasn't flexible to user's differing requirements.  Very different to writing software that is used in-house by a single company.
• I was very surprised when I learned that there are still users happily running this system today.

Other Projects

Various Other Systems

I have been involved in numerous other systems, including:

• Bill Of Material system running alongside Accpac.
• Dance Event Scheduling System.
• Debt collection system add-ons.
• Medical insurance system.
• Stock market portfolio management.
