Software Developer

With a physics degree from Imperial College and a post-graduate degree in Remote Sensing from University College London, I was privileged to work for the UK Meteorological Office in June 2000.

My main responsibility during my time in the Met Office was to develop and maintain the Unified Model. The UM is a climate model, which the Met Office uses for weather prediction and climate research. It contains physics and dynamics of atmosphere and ocean and their interactions, written in ~2500 decks of Fortran code. The UM is supported by a sophisticated compiling system, control codes, user interface and archiving system. In addition, varies file utilities have been developed to display and compare output diagnostic datasets, to perform arithmetic operations on them and to convert their format to use on different platforms or image packages. Each output diagnostic dataset with normal resolution contains 96(longitude) x 72(latitude) x 38(level from ground to top of atmosphere) digital values representing a particular physical data of the globe. As the UM programs are executed on Massively Parallel Processor machines, I was privileged to gain insight into parallel computing.

I am experience working with the large climate datasets the UM generates, which have complex data structures and formats. As the owner of a bundle of file utilities and software. I was responsible for their development, maintenance and testing. I have undertaken a project to automate file utilities testing processes. The test harness was written in Perl and Unix scripts, and in-house revision control system was used to manage different versions and releases.

Another project I have undertaken was to design and implement a ?Climate Diagnostic Search Engine?, allowing climate scientist to query and search for different climate data. It was a web-based application, written in HTML, CGI and Perl. I was grateful to be given those opportunities to employ my innovation and creativity.

My another important role in the computing technique team in the Met Office was to plan and carry out acceptance tests for UM version upgrade, to ensure that all outcome from the new version of the climate model were comparable down to the bit value with those in the previous version. Memory performance tests and configuration tests were also performed and carefully documented.

Last year, a more powerful supercomputer SX6 is being installed to replace the current T3E machines. My additional responsibility was to involve in building file utilities on the new supercomputers and performed acceptance tests to make sure output were identical to those on the T3Es.

As a member of the UM helpdesk, I was also responsible to investigate software problems encountered by climate scientists. Many of the problems were highly challenging. Hence, I have developed strong analytical skills for problem solving to meet the high demand of our users.

With minimal amount of supervision, I needed to use my own initiative to manage the substantial amount of workload. Good time management and workload prioritization were important elements to ensure deadlines were met.

With my aptitude and enthusiasm in programming, I believe I would make vast contribution to your company.
