What I'm looking for

I'm looking to build end-to-end data and machine learning solutions that solve business challenges, from data pipelines and experimentation to production deployment, monitoring, and measurable impact.

At OLX Group, I build analytical solutions and machine learning models that support strategic decisions and generate business impact. I developed Julius, using clustering and Multi-Armed Bandits to optimize discount strategies and deliver a 34% revenue uplift.

I also led end-to-end development of a Seller Reputation model that tripled transactional sales among sellers with an established reputation. My work spans data acquisition, ETL, feature engineering, model development, API deployment, monitoring, and retraining.

I build data pipelines with Python, SQL, Spark, Trino, and Amazon Athena, and deploy production models through GitHub Actions, Apache Airflow, MLflow, COPS, and Amazon SageMaker.

Before becoming a Data Scientist, I delivered strategic analyses, dashboards, KPIs, complex SQL queries, and process automation as a Data Analyst at OLX Group and an Operations Analyst at Softplan. I communicate data-driven results with both technical stakeholders and business teams.
