Software Developer/Architect

Saravanan Subramanian

 

My hobbies include tennis, weight lifting, photography and reading. I also try to pen my thoughts here on a number of topics that interest me which include software development/architecture as well as history, science, mathematics, linguistics and travel. I am also working slowly on completing an e-Book (on HL7, DICOM and PDF programming) for release next year.

Hello, Visitor. My name is Saravanan Subramanian (சரவணன் சுப்பிரமணியன்), an old Tamil name that is pronounced “seruh-va-nun sue-bruh-money-yen”). I live in Regina, Saskatchewan, Canada, and make a living designing, developing and documenting web, mobile and desktop-based software applications using a number of object-oriented tools and technologies.


Over the last fifteen years, I have helped solve information technology problems at large financial and healthcare-related organizations. The applications I have helped build over the years include  graphical desktop as well as rich Internet applications for data entry and display, tele-radiology, alerting and notifications, as well as secure document transmission, messaging and generation using PGP, XML, HL7, DICOM, Office and PDF standards. 


I have many years experience in developing messaging applications using both commercial and open source middleware. Currently, I am working on on a number of challenging projects involving web application development, enterprise messaging, business intelligence and reporting, as well as electronic content management.


Technologies and standards that I am most comfortable with include Java, .NET, XML, PDF, DICOM, HL7, Adobe LiveCycle, Mirth Connect, Oracle and SQL Server(see my profile). If you need reach me, please send me an email, or leave me a voice message at (306) 501-7542.

"Responsible (software) development is the style of development I aspire to now. It can be summarized by answering the question, How would I develop if it were my money? I’m amazed how many theoretical arguments evaporate when faced with this question."  ~ Kent Beck

INTRODUCTION TO THE DICOM STANDARD (USING OSIRIX)

I decided to write an introductory tutorial on the DICOM standard as there were not many articles on the Internet that singularly cover all aspects of this very large standard through an example based approach which helps the learner relate to the underlying concepts quickly by means of association. Many people I know who work with DICOM on a daily basis often deal only with a few aspects of this vast standard. Read more...


UNIT TESTING 101 FOR NON-PROGRAMMERS

Seeing the many challenges in the field in terms of adopting unit tests, I am totally convinced that a basic awareness needs to exist of the inner workings of unit testing even for the non-programmer who works closely with software delivery teams to ensure that teams use unit testing to help produce high quality software that is easy to enhance or modify. This article explains the fundamentals of unit testing as well as how to adopt unit testing within your organization. Read more...


HL7 PROGRAMMING USING JAVA - A SHORT TUTORIAL

Before we get started on this tutorial, have a quick look at my earlier article titled “A Very Short Introduction to the HL7 2.x Standard” for information on the HL7 standard. Please note that this tutorial assumes you know Java or any equivalent object-oriented language. A basic understanding of network as well as thread programming is also useful, but not necessary. Building custom Read more...


AUTOMATING PDF-RELATED STRUCTURAL TESTING

One of the frequent challenges specially in document centric organizations where production of documents is often highly automated is to ensure that these documents are correct both structurally and semantically before they are transmitted both for internal and external consumption by other Read more...
