Lead data science consulting practice serving 80+ global clients across retail, enterprise, and technology sectors. Drive business transformation through AI strategy, predictive modeling, and advanced analytics solutions.

Freelance Data Scientist

  1. Responsible for the end-to-end delivery of data science and AI projects, from initial scoping and technical assessment to deployment and handover.
  2. Analyzed business and operational requirements and translated them into scalable data and ML system designs. Defined data architectures, ingestion strategies, and processing pipelines for structured and unstructured data from heterogeneous sources.
  3. Designed, developed, and maintained data pipelines (ETL/ELT), ensuring data quality, reliability, and efficient update mechanisms. Implemented normalization, validation, and monitoring processes for long-running production systems.
  4. Developed, trained, and validated machine learning models, including predictive models, NLP pipelines, and computer vision systems. Deployed models into production environments and integrated them with existing platforms via APIs.
  5. Built MVPs and prototypes with a clear path to scale, avoiding early architectural decisions that would limit future growth. Defined technical roadmaps and advised stakeholders on trade-offs between speed, cost, and long-term maintainability.
  6. Collaborated with product, engineering, and business stakeholders, providing clear communication of technical concepts and results. Delivered documentation and knowledge transfer to internal teams.
  7. Operated in cloud environments (AWS/GCP), using containerization and version control (Docker, Git) to ensure reproducibility, security, and maintainability.
