ABOUT ME

It’s David, Professional Data Scientist. I have various skills and experience in Data Science field. I will be glad to contribute to your projects in mutually beneficial way. If you have business idea and check to validate it with MVP or you have established services I can embark and make the journey more successful.

My skills include machine learning, deep learning, computer vision, full stack development, web scraping, data engineering, web development and data visualizations. My main programming languages are Python, R, Javascript and SQL. I can create interactive web applications and dashboards using Python’s Dash framework and R’s shiny package so you will be able to observe, analyze and present various aspects of your business and other activities in effective ways. In addition I can build websites and mobile apps using React, Next.js and React Native.

I also have developed skills in DevOps / MLOps. In particular how to deploy Machine Leaning or Deep Learning model into production on a cloud based or any other web server. So this step is very important in data science paradigm as the value for model is generated during production environment.

TESTIMONIALS

Reuben Vandeventer

Reuben Vandeventer

CEO | Founder, SecondSight

Our team has been using Upwork since it began, and amongst us have engaged hundreds of freelancers. David is by far the most talented freelancer we’ve ever worked with. He has the perfect balance of technical competence, ability to quickly learn new things, and creativity to design elegant solutions to complex requirements. This particular project spanned across not only python and D3 challenges but the implementation of complex mathematic methods taken from algebraic topology, graph theory, and some of the more esoteric nuances of machine learning. Our team will definitely use David again on future projects.

CEO, Equeum

David took up a difficult and experimental initiative focusing on a highly domain specific application with verve. We were very impressed with his ability to work independently, to present findings, and to manage the research, development, and deployment pipeline end to end for a large and complex dataset. He is excellent about communicating the rationale behind his decisions in the context of data analysis, especially given the asynchronous nature of remote work. David: Kudos! Thanks for your contribution, and we look forward to working with you again in the future!

David Imrem

CPO, SecondSight

David has been an incredibly valuable resource to my R&D team to explore a use case that we’ve been working on for many years. The area of focus for our use case involved algebraic topology and graph theory to be used for high-dimensional feature discovery and analysis. The process our team used with David was to guide particular math challenges that we understood from an abstract standpoint but needed a prototype that resulted in either data frames or working visuals to which we could provide additional guidance. This process resulted in a very loosely defined framework that David had to adapt. As a data science company, we have observed in the many other data scientists that we attempted to use before David for this same project that the loose definition of requirements is counter to the typical workflow of data science and, even more broadly speaking, engineering. David proved he had the skills and abilities to help us define what requirements should be as we progressed through the project together.

Managing Partner, FCL Analytics GmbH

David is an ambitious, conscientious and reliable partner. He incorporated his own ideas into the project, which helped us a lot as non-technicians. If we find clients who would like to work with us, we will be happy to continue working with David. Thank you very much for the trusting cooperation.

Director of Operations, ScanLabMR

David was fantastic to work with! He was excellent at communicating with our team and making sure that every task was done to meet our deadlines. He was innovative and always had alternative ideas to offer if needed. We will definitely work with David again should another project come up.

Cary Sparrow

CEO, Greenwich.HR

David does outstanding work, is excellent at communicating and keeping us informed, and is a proactive thinker. He understands the objectives and not just the tasks, and is collaborative to optimize the approach he takes to best meet the objective. For this project, we tapped into his strong expertise in web scraping methods and database operations. We absolutely plan to be working with David in the future and can highly recommend.
