Background

I graduated from Huddersfield University in 1993 with an Honours Degree in Electrical and Electronic Engineering.  I then worked in the electronic industry and in 1995 set up my own design company.  With the growing demand for micro-controller and PC based products, software development became an essential skill, from the arts of embedded assembler and C for micro-controller platforms through to full Windows applications.

Since 1997, my primary focus has been on Information Technology, mainly Internet technologies. Conducting my own business through the web has lead to being commissioned by companies to develop both client and server side Internet applications.

In July1999, I worked a 4 month contract with the Trader Media Group and was subsequently offered and took the permanent position of Senior Developer, being involved with the full product lifecycle and remained an employee until August 2001.

I then had the opportunity to move to a Small but growing Internet Consultancy Company to aid with their internet products and client development, again in a senior position with responsibility for product development.

Recently

During the past fifteen months I have been contracting my services and have undertaken four contracts whilst looking for my ideal permanent position. I am glad to say, that I have recently migrated my skills from VB6 to VB dot NET, gaining over four months experience, which has been a great leap forward and an exciting time for my personal direction and development.

I am currently executing a short assignment to help a local company with their internal IT systems, commissioning a Windows 2003 small business server environment, configuring their networks and internet connectivity. I am also developing a website to improve their online presence.

Innovation Productions Limited (Contract Consultant, September 2003 to January 2004)

Background

This was an unusual yet exciting role, developing a flexible multimedia rich game show system to form part of the extensive entertainment line up for the new Cunard Queen Mary 2 (QM2) cruise liner.

The system consists of five lecterns, each with a dual head PC, two LCD monitors, a touch screen and four “buzz in” buttons. There is also a PC behind the scenes that is the master controller and is also responsible for playback of multimedia content to the ships audio visual systems and lighting desk. All communication between computers was implemented using XML over UDP.

In order to make the system as flexible as possible, I developed of a “game show description language” whereby a game show or other entertainment show can be described in XML, together with an object orientated interpreter written in VB.net which implements the game show based on the XML description.

Carcraft of Rochdale (Contract Consultant, March 2003 to July 2003)

Background

This was a varied role, working with a small team of developers on a distributed N-Tier COM+ Win2K SQL Server 2000 based system written in VB6. The system integrates functionality required for all departments of the business across multiple sites. My role involved gathering requirements, analysis, and development of new functionality as well as extending existing functionality and fault tracing / debugging. Some junior developer mentoring was also undertaken.

Technical Skills

Visual Basic 6, ActiveX Controls, ActiveX DLL’s, COM+, User Interfaces

SQL Server 2000, TSQL, ADO 2.7, XML, XSD, VSS Automation

Personal Skills

Gathering requirements, Analysis, Design and Implementation.

Team Working and also the requirement to work alone.

This role also involved some mentoring of junior developers.

Below, I have outlined in more detail, the main developments I was involved with.

Purchasing Department

Added a new module to give the purchasing department various functionality to track pricing and valuations.

This involved gathering business requirements, analysis, design and implementation across all tiers.

The client tier was developed using VB6, Custom ActiveX User Control, and integrated into the existing MDI Business application.

Business tier components were developed in VB6 creating ActiveX DLL Transactional Components that were deployed in COM+ on Windows 2000

An extension on the database schema was required to implement the new functionality. This involved extending the existing SQL Server 2000 schema by adding new tables, and store procedures. Tuning of stored procedures and table indexing was undertaken to increase the performance of complex searches.

Generic Client side form Validation Component

I identified the need for a consistent approach for client side form validation across the whole system, in order to improve the user experience and decrease round trips to the server. After determining the requirements I developed a generic VB client side activeX component (DLL) that worked with forms and user controls to validate the data entered into its controls by the user. Data type, range and length checking and regular expression matching are some of the attributes that can be enforced. The system also handled dynamic tool tip and user message generation.

The rules for validation for each form were described in a XSD validated XML document which resided in the database. The client application would request the validation documents from the database via the business layer and cache them for the lifetime of the application, thus minimising round trips through the tiers of the system, but still marinating the benefit of holding the documents centrally.

Support Tools Developed

In conjunction with the validation component, I also wrote a suite of tools to aid members of the development team integrating the new validation component.

The validation analyser tool allows the developer to analyse VB6 forms and user controls in existing projects. The tool writes VB Source code to be included in the form / user control to utilise the new validation component. It also writes a skeleton XML validation rule document. This saves the development team days of manual coding, increasing productivity and ensuring consistency and accuracy.

The XML Editor Source Control tool allows the team to manually edit the XML validation rule documents in a Source controlled environment. It connects to Visual SourceSafe 6.0 using Automation and to the SQL Server 2000 database where the documents are deployed.

Project: Forms Integration

This role was a short term contract to migrate an existing IBM FORMS system to an Intranet based system using VB6 COM, SQL Server 2000 and ASP running on IIS5 (Windows 2000 server). This role involved creating new ASP based forms for the user interface, COM classes written in VB6 registered with COM+, together with TSQL stored procedures encapsulating business logic and data abstraction layers. Client side form validation was implemented using JavaScript to minimise round trips to the server. The system uses NT accounts and is integrated with LDAP and Exchange server to authenticate users and provide email functionality.
