About

With over a decade of experience in data science and tech leadership roles, I specialize in developing advanced predictive analytics models and managing end-to-end product development cycles.

Throughout my career, I've led teams, managed projects, and optimized algorithms, leveraging my expertise in machine learning, deep learning, and statistical analysis to solve complex problems and deliver high-impact solutions. In my recent role as a Data Scientist and Tech Lead at Modus for DTEK, I successfully led multiple projects to achieve high ROI and positive outcomes, while also overseeing team management, product design, and validation procedures.

Best back-end engineers I've ever worked with...​

“I interviewed about a dozen different firms. DevsData LLC is truly exceptional – their backend developers are some of the best I’ve ever worked with. I’ve worked with a lot of very well-qualified developers, locally in San Francisco, and remotely, so that is not a compliment I offer lightly. I appreciate their depth of knowledge and their ability to get things done quickly. “
