Primarily I'm an academic researcher. I have my PhD in theoretical physics. My field is quantum information science, applied mathematics and operations research. I have five years of experience as a software engineer, database programmer and algorithm developer at an IT company. As a freelancer I may undertake the following tasks for hire. I'm ready to assist researchers in my broader field (general physics, quantum mechanics, quantum information, classical and quantum optics, operations research, transportation science, and certain areas of computer science) to formulate their results in a publishable form. Assistance includes proper formulation from a draft, professional criticism, verification of bibliography, and typesetting in LaTeX. I have published over 30 research papers in prestigious journals, I'm a referee for 7 journals, and editor of one of them. (Note: I do not perform other tasks in your research, I reserve my time for my own research. I do not assist for hire in research directly in my narrower scope or with potential conflict of interest.) I can assist in the preparation of research grant proposals (in case I have no conflict of interest and it is not submitted to any agency I work for as an evaluator.) I can apply results of public results of operations research and mathematical optimization, design and implement various business scenarios, especially related to transportation and scheduling. As a UNIX power user I can solve simple as well as complex problems requiring advanced shell scripting. I can do scientific programming in python or Matlab.
