I am a PhD in Computational Seismology. I am willing to do the job you said. I am expert in Python, Perl and GMT (Generic Mapping Tools). I can do plotting in GMT for you, can write data pre-processing and post-processing scripts in Python and perl too. I am skilled to write bash codes in Linux. Further, I have published ~10 SCI paper in high ranked journals e.g. BSSA, Tectonophysics, JGR Solid Earth etc, and editing and proofreading of manuscripts for more than a dozen papers.
