Project history

Senior Data & AI Solutions Consultant

Internazionale (media & publishing)

Media & Publishing

  1. Built first unified analytics and reporting pipeline by integrating 5 heterogeneous data sources (GA4, app analytics, Watuppa, Spreaker, Mailchimp) via APIs, with ingestion of tens of thousands of daily events through Google Cloud Functions into BigQuery to create a scalable data model.
  2. Designed a Looker Studio dashboard to monitor key KPIs: subscriber activity, subscription trends and churn, podcast and newsletter engagement, high-performing content, benchmarked daily and over long-term trends, replacing manual, fragmented reporting workflows.
  3. Enabled data-driven decisions for content strategy, promotional campaigns, and audience growth through centralized reporting and actionable insights.

Senior Data & AI Solutions Consultant

Europass Teacher Academy (educational services)

Other

  1. Built and automated a scalable Python ETL pipeline with Google Cloud Functions, consolidating 15+ data sources (including GA4) into BigQuery to fuel Looker Studio dashboards, saving 50+ hours/month and enabling strategic insights on revenue, seasonality, and course demand
  2. Automated survey response extraction via SurveySparrow API, replacing unstable Zapier workflows with a robust Google Cloud Function, achieving 100% data reliability, recovering 10% of previously lost inputs, and unlocking real-time analytics via BigQuery and Microsoft Graph API

Data Analyst

Springer Nature (academic publishing)

Media & Publishing

  1. Designed a Python-based time series forecasting framework to predict weekly publication volumes, improving prediction accuracy by 25% over previous projection models, streamlining resource allocation for typesetting vendors and improving operational efficiency
  2. Built scalable data pipelines using BigQuery and Looker to monitor workflows across 400+ journals, reducing average publication time by 1.5% (3 days) despite a 40% YoY surge in submissions
  3. Presented data-driven insights to VPs and senior leadership, aligning technical findings with strategic priorities and influencing decision-making
  4. Mentored a data analyst intern, streamlining reporting workflows, while boosting team productivity and leadership skills

Data Scientist and Engineer

Chancen eG (financial services)

Banking & Financial Services

  1. Built a Python-based ML algorithm to extract and process Salesforce data, predicting high-risk repayers with 80% precision. The model streamlined loan eligibility decisions, contributing to a 15% reduction in student selection time through predictive risk profiling
  2. Designed a scenario analysis tool in plotly to simulate repayment behaviors of student cohorts based on economic and behavioral conditions, supporting strategic decision-making
  3. Improved Monte Carlo simulation models for income share agreement conditions, deployed on Amazon Web Services

Post-doctoral researcher in Mathematics

Freie Universität Berlin
Postdoctoral Researcher funded by a 200k euro two-year DFG Individual Research Grant
  1. Developed a state-of-the-art Python algorithm using linear programming in Gurobi to test the realizability of combinatorial polytopes, a high-complexity optimization problem in geometry
Supervisor for a Master’s thesis on Image Compression using clustering
  1. Implemented a Python algorithm for Image Compression using clustering models to redraw images as partitions into cells whose color approximate the original image
Postdoctoral Research funded by Einstein Foundation
  1. Developed the SlackIdeals package for the computer algebra system Macaulay2 (based on C++), implementing methods for manipulating slack matrices of convex polytopes and matroids

Data Scientist

Shoppar LTD

Marketing, PR and design

  1. Built a gradient-boosted regression model in Python to predict in-store customer attention span when watching video ads, outperforming baseline by 35% and revealing optimal ad durations by customer segment
  2. Delivered a PoC for marketing content optimization using image tagging and OCR with pre-trained neural networks, enabling targeted video ad segmentation by customer group

Data Analyst
