Leading a global team which is responsible of building ML models and data solutions for fraud detection.

Leading a global group in the fraud detection domain with four data science teams and a cyber security research team.The group is responsible for the following domains:Customer authentication: building ML models and features that evaluate the risk for unauthorized users on all user logins and other user actives. The team had built a continuous delivery environment for deep learning models.Sign-up and new users: building models and features that evaluate the risk on sign-up and new account lifecycle. building solution to identify fraudulent account creations and tools such as BOT, proxys, etc. Optimizing risk data solution to specific products such as Crypto coins, recurring payments and others. Risk data acquisition: responsible for user data retrieval (such as keystrokes, device and network intelligence) and processing for all fraud prevention groups.

Leading a group which is responsible for developing data solutions and data science frameworks. These solutions are used by multiple data science teams across multiple business domains. The infra group develops the long term solutions using cutting-edge big-data technologies.

Leading a group of data scientists.The team develops analytic graph platforms that generate behavioral insight for fraud-prevention, credit, anti money laundering and other risk solutions.

Research, design and build text-mining and graph processing applications.Product Owner (agile) of the Hadoop development team (in China).

Managing two algorithm teams (ten engineers) at the CTO office.Responsible for solution architecture, algorithms, system design and software development of new products.The group has developed a high scale & real-time video delivery and caching over HTTP.

Managing four algorithm engineers in the area of video processing algorithms such as video compression, ad insertion, IPTV, adaptive bitrate streaming and TCP manipulations.I had a major contribution in providing the ad insertion solution over encrypted stream for AT&T and directly faced the customer.

Responsible for designing, simulating and developing algorithms for ad insertion and network bandwidth management.

Responsible for architecture, specification and development of large security systems.Leading a software development team of ten people.
