Work Experience
Lead Data Scientist
Duenders LLC
- Developed a neural search based on Jina and transformers embeddings.
- Deployed serverless containers on the cloud running on specific schedules.
- Oversaw the development of a web and mobile app in the fintech space.
Big Data Engineer
Deloitte
- Worked on a company-wide solution to have a unique view of customers with data from multiple sources.
- Built ETL pipelines that extract and ingest data from various database systems using big data technologies based on Palantir Foundry.
- Developed and tested data sources that provide feeds to data lakes and their deployment in production.
- Designed pipeline specifications by integrating the business logic with consumers' requirements.
- Communicated with project managers and business analysts to optimize the efficiency of data pipelines.
Data Modeler
Credit Suisse
- Contributed as a contractor to modeling and analyzing different financial data for identifying money laundering.
- Acted as a product owner in an agile workstream comprising of up to 10 developers and business analysts. Identified and prioritized business requirements, then converted them into technical implementation tasks.
- Analyzed machine learning models that have been developed with a focus on explainability.
- Ensured the model technical performance metrics reflected the business use case.
- Conducted ad-hoc analysis of clients' transactional behavior to detect money laundering patterns using state-of-the-art big data technologies based on a Spark cluster.
- Proposed and participated in a project-wide strategy for the implementation, productionalization, and post-deployment monitoring of ML models.
- Represented the team in discussions about collaborations with external data providers.
Data Scientist
BIS – Bank for International Settlements
- Developed an end-to-end system to identify various cyber threats and malicious behaviors.
- Built NPL-based detection models—spam classifier built on top of BERT with PyTorch implementation, prioritization model for cyber alerts in the scikit-learn security incident response platform, and anomaly detector for processes commands lines.
- Developed detection models based on network traffic, targeting DNS tunneling, admin access traffic, and malicious domains. Used PySpark for data processing and MLlib for ML models.
- Collaborated with the team to develop the BIS's big data platform based on Apache and Cloudera products. Gathered hardware requirements, selected software tools, and defined use cases.
