Broadly my areas of expertise are object oriented design and development, relational database systems, web and Android app development, GIS spatial analysis, statistical analysis and mathematical modeling. I have ten years of experience with R and I really enjoy making R Shiny web apps that provide GUI interface for data wrangling, data management, machine learning, interactive data visualization, image and video processing/annotation and automatic report generation. My greatest strength is the ability to design software systems that are modular, scalable and extendable. I also enjoy the challenge of creating “creative” and “elegant” software that automates tedious repetitive tasks, saves time, reduces human error and increases productivity significantly.

    “It was a great experience working together with Karpagam in all aspects. Karpagam showed initiative in all her endeavours and is clearly a self-starter. She works very responsible and has a wonderful character and very impressive IT-knowledge and is a very good programmer, always interested in getting the best solution. I recommend her as a good person and a hard working individual. For me it is clear, that she will always be the first person to ask for working for me on another project.”

independent Software Engineer/GIS Consultant

Aug 2017

I am designing and developing a software system to perform computationally intensive Geo-spatial analyses of remote sensed data with cloud computing by linking to Hadoop via R.

Independent Software Engineer/Ecology Consultant

Mar 2017 - Aug 2017 (5 months)

• Developed an Android application for collecting data with mobile devices for a tiger conservation project. • Designed, developed, implemented and tested a MySQL RDBMS • Designed, developed, implemented and tested a web app using R Shiny for: data upload, data visualization data processing, data analysis (R-stats, R-GIS) and automatic report generation (RMarkDown).

Coordinator of Scientific Research & Monitoring

Nov 2016 - Feb 2017 (3 months)

• I designed research methodologies (sampling design, statistical analysis and inference and scientific report writing) for tiger ‘camera trapping’ projects in tiger habitats of Assam • I developed an Android applications for data collection in the field. • I wrote R scripts to automate, data sorting especially thousands of wildlife photographs from camera traps

Research Associate

Jan 2014 - Jun 2016 (2 years)

Worked on the movement ecology of African elephants in Kruger National Park (SA). All data processing, mathematical modeling, statistical analysis, data visualization and GIS processing were done using the R programming language. Analyzed high volume location data (~1.5 million geo-points) of fifteen GPS collared wild elephants in Kruger National Park, SA and remote sensed fire data (~7000 fire polygons) for a period of 2005 to 2012

Software Engineer

May 2000 - Sep 2003 (3 years)

• Implemented search heuristic (A* algorithm) for a location based server to find the optimum path between source and destination addresses on ESRI road network data (C++ on Solaris) • Incorporated live traffic density information into consideration for computing optimal path in terms of travel time (C++ on Solaris) • Implemented real time traffic information display on maps delivered to mobile phones (Java).

Software Enginner

May 1998 - Apr 2000 (1 year)

• Implemented algorithms for sorting cheques on sorter machines in banks (VC++,Windows NT) • Designed and implemented a viewer to inspect “live” server memory using shared memory pages (VC++, Windows NT)

Software Enginner

Jun 1997 - May 1998 (11 months)

Implemented string processing algorithms to detect and correct “Y2K” bugs in legacy codes. I implemented some of the string search algorithms in PROLOG and others in Perl/Tk on Solaris platform.
