    I am an experienced data scientist with background in medicine, nanotechnology and computational physics. I have delivered data science consultancy for different companies depending on their needs and domain. I have succeeded in delivering results where other people fail. I am talented to deliver custom algorithms specially tailored to your business case and automate them so they are reusable for you in the future. I have worked with medical companies providing diagnostic machine learning algorithms for their needs. I have worked with consumer companies providing exploratory data analysis and basket analysis (affinity analysis, which products are sold most often together) along with recommendation engines for their customers. Have solid data extraction, cleaning and exploratory data analysis skills along with model building in machine learning algorithms for structured (databases) or unstructured (text) data. Can also perform graph analysis for all your needs depending on your project. The starting point of every project is to discuss the needs of the clients and set up an efficient data extraction - cleaning and transforming pipeline which will then be passed to any machine learning model. Can deliver all the above in an API for example in Azure ML or BigML platform so that the whole process can be streamlined and reused according to your business needs. Can also provide your private server in the cloud with the algorithm pre installed and interfaced securely and privately through the web for your needs.
