    I am a scientific researcher and freelance editor/proofreader with knowledge of physics, chemistry, astrophysics, biology and computing. I have a PhD in physical chemistry and a first class master's degree in physics and astrophysics.I have extensive experience in scientific and technical writing, with papers published in high impact, peer-reviewed journals such as Nature. I offer a comprehensive editing and proofreading service, which goes beyond just checking spelling and grammar. I specialise in preparing papers for journal submission and often work with authors whose first language is not English. As a published scientist, I understand journal requirements and what reviewers look for when assessing papers.  less

    I have 10 years of experience in different areas of software development. My most recent experience lies in field of backend development of horizontally scalable solutions for data processing. During last 2 years I have been developing from scratch proprietary framework similar to Apache Hadoop and Spotify Luigi for batch data processing (billions of log records of ad data daily). I used Python as core language to promptly prototype data analytics business logic with a goal to rewrite it in native language without API changes later. This project also involved managing NoSQL databases (TokuMX or MongoDB 3+ with an appropriate storage engine) to process, aggregate and store massive (hundreds of millions daily) number of documents, indexed for further statistical analysis and reports generation. I also have experience in the following areas: - development of web backends in Python using uWSGI and Tornado frameworks - automation of code building and deployment, Vagrant, Docker - C# language and some experience in Java and C/C++ I am an open-minded technology enthusiast with strong algorithmic and mathematical background and keen attention to details. New language, technology or framework required for next project is not a problem to learn at all. I am ready to show positive, constructive and helpful attitude to your tasks.  less

    I started as a physics teacher after my graduation from university but I always had in mind to become a scientist and if possible to combine that with teaching. Also, as I like biology it was always my goal as a scientist to apply physics to the study of biology. During my MSc and PhD research projects, both on plant physiology, I extented further my knowledge on plant sciences, namely plant physiology & biochemistry, plant anatomy and the experimental methods used in these disciplines. Over the last 6 years I have especialized on mathematical modelling of plant transport systems (membrane transport, phloem and xylem transport) for which I used Mathcad as my main tool for solving differential equations. Also, on the experimental level I have experience on isotope labelling, electrophysiology and the standard methods and equipment used in those fields.  less
