Alexey M.

I am a data leader and strategist with over 15 years of commercial experience in data science and technology, digital and data-related domains. leading high-performance teams, with a strong track record in the most progressive multinational global companies in Asia and the Middle East. I would like to offer comprehensive turnkey consulting services and development in the field of ML-backed product recommendation services and ranking in E-commerce, which *sell* and work in Big Data setting under high loads. I will do everything end2end: - Business analysis and problem setting, - Data acquisition and scalable exploration ( Spark, Flink, Supersets), - Present actionable data insights - Implement models using Tensorflow, Spark MLib etc and all well-known non-deep models - Do offline validation using EconML or the like, - Design A/B tests and interpret the results - Design the rollout strategy - Solve related engineering challenges ( latency, graceful degradation, fallbacks, etc ) Recommender systems are a big math puzzle and textbooks mention just disconnected mathematical abstractions. not end to end solutions. But how will you combine these pieces to make a real working system -- this is the answer, which I accrued over the 15 years of my experience, this is not published everywhere and I'm very keen to help you be successful and maximize the GMV Recommender systems go hand by hand with the learnable ranking of your products, which also has a lot of nuances. Just training your favorite LambdaMart ranking using CatBoost or Tensorflow is not enough. You have to balance relevance and diversity, solve discoverability problems, and many more. Once again, I'm more than happy to help! Besides ranking and recommendations I solve a broad range of smaller problems in e-commerce where traditional ML libraries like XGBoost/LightGBM/Spark MLIb are applicable, including but not limited to e-commerce inventory optimization, expiring items prediction, supply-demand management and supply crunch prevention, model-based upselling/cross-selling, cross utilization of services, customer funnel modeling, etc I have extensive experience in computer vision for engineering applications ( steel defects detection, radiology applications etc ) and many other domains of expertise. Let's have an introductory call for me to reveal all your aspirations and address your needs today, not tomorrow!
