R&D Engineer - Machine Learning | Deep Learning

Remote work, Ukraine · $5000 · 9 years of experience · Advanced/Fluent

Languages: С++, Python, CUDA-C, C#, R (sorted according to the amount of experience in decreasing order). Know, can do (and love to do) everything around Computer Vision, Machine Learning, Deep Learning. I have PhD in Functional Analysis, Master degree in Applied Mathematics.

computer vision, Deep Learning, Machine Learning, С++, CUDA, OpenCV, Python, Git, C#, Jira

In 2010 I've developed a core of content-based image-retrieval engine called WeSEE:Search. When the number of images reached 200 millions I've developed image duplication detection algorithm based on local features. From 2011 till now I develop content-based advertisement targeting solution WeSEE:Ads. It uses images and video from webpage and a lot of Computer Vision algorithms to predict the best possible advertisement. The main technology used is Deep Neural Networks with 15-30 layers for different taks: general categorization, face recognition, age and gender detection, brand-safety. This technology is used by dozen of companies in UK. Currently working for few startups in Israel and USA. I develop Deep Learning systems for them.

I love complex problems :) Interested in Computer Vision, Machine Learning, Deep Learning - everything else won't work out for me.

Senior Software Engineer 🔥

eu, scandinavia · $3500 · More than 10 years of experience · Advanced/Fluent

Working in different roles from software developer to team lead, the most part of my career used to spin around C++ exclusively with a good deal of reverse engineering involved, yet for the past 4 years I've been broadening the area of my interests which now includes new tools as well as the entire fields like natural language processing and DSP. Among the various projects I have been involved with there are: - a machine learning model suggesting new words from an article basing on the articles that have been read and thus extending a language learner's vocabulary. The model utilizes word2vec embedded vectors in combination with a traditional binary classifier such as SVM; - a tool with a mixture of technologies within to create encrypted bilingual books for eBook reader. Entailed creation of a javascript component for parallel editing of bilingual texts, along with employment of Haskell Yesod and Electron framework; - a product for media exploitation and forensic analysis of digital devices starting from personal computers to smartphones. Among the distinctive features were pre-configured search profiles, by virtue of which it gained popularity in federal agencies of various countries including U.S. Homeland Security and U.S. Special Operations Command; - a processor module for the popular disassembler/debugger IDA Pro to analyze mCore assembler code of iDEN mobile firmwares from Motorola. The processor module was developed as a part of a bigger reverse engineering project and ultimately its source code was contributed to iDEN hacking community;

In the role of a C++ software developer the biggest achievement has been design and implementation of a versatile device-detecting library - easily configurable, expandable and cross-platform, which beside my own team was adopted by other teams as well. As a team lead, despite taking an active part in kicking off of a completely new team at the new location along with creating continuous integration infrastructure from scratch, I reckon my biggest achievement nonetheless was the high quality of code produced by the team due to utilization of unit testing alongside with automation testing wherever possible. In the role of a reverse engineer the biggest achievement was a 6months+ project on Motorola iDEN mobile phone where I had to learn to extract its data whereas there had not even existed a tool to analyze its firmware. The result improved the marketing value of the product as it became the only one supporting iDENs at the time. Yet it has been long since I did that and have no intentions to get back to reverse engineering. It's here only for the sake of completeness of my previous background. In spite of all stated above, the most recent and the most valuable achievement for me so far has been a machine learning model which will let me finish a piece of software aiming to extend a foreign language learner's vocabulary naturally according to one's reading likings. The model was implemented in Python as a proof-of-concept, evaluated on cross validation/test sets, ultimately the most fit machine learning algorithm was chosen and its parameters adjusted according to the goal.

Having discovered an interest in math, I've decided to do away with reverse engineering, so today I'm more interested in gaining experience in projects with a scientific background.
