Co-founder

Fractile

Designed and co-implemented a platform to create, customize, and apply AI agents. The agents disposed of an additional layer of security, thanks to the anonymization service that protects 100% of the data from the client's server. Applied AI agents with the ability to learn on previous tasks and be spawned via Chat, API, or Jira. Deployed the solution to two medium-sized companies.

Warsaw Stock Exchange

Led the development process of a scalable exchange platform for personalized ads on Polish TV. Designed logo placement detection AI in live-streamed TV broadcasts. Led the development team of nine, implementing a supply-side platform, end-to-end, from conceptualization and MVP to a scalable production stage. Created an end-to-end pipeline to train the behavioral models based on the data from TV.

Jan 2021 — Jan 2023

Lead Data Scientist

Sweetgreen Inc - Main

Designed and led the implementation of the salad recommendation engine at the production level. Created a BI tool with live-updated sales data and ML forecasting for the CxOs. Built a PoC sales forecasting model based on historical sales and weather forecast data. Improved the legacy ML production models for supply chain forecasting. Managed to improve the processing time by one order of magnitude.

Jan 2020 — Jan 2021

Senior Data Scientist

Meloncast

Created a complete training and deploying pipeline for NLP models (BERT) to classify target audience marketing texts.
