Experience

User Recognition

The user-recognition project had the aim to recognize users by their activity on the network. It was a large software project composed of more than 30,000 lines of Python code containing highly optimized data pipelines and advanced machine-learning algorithms. The project lasted more than one year, and I have been responsible for the development from the initial statistical research to the full implementation of the product.

Anomaly Detection for Large Scale Network Data

I developed an anomaly detection system from scratch that can detect faults and anomalies in a network system. The software was able to analyze more than 100,000 series in real time and is currently used by many trading companies to monitor the efficiency of their networks. I handled both the model research phase and the actual implementation of the system.

A/B Testing for eCommerce SaaS

Worldz is a SaaS plugin that eCommerce businesses can add to their site to improve conversion rate and revenue. I developed the AI portion of the software, designing and implementing A/B tests and optimizing the tool.
