About Me


Machine Learning Engineer at Aprix with an international background in AI, Data Science, and Operations Research. I hold a double degree in Engineering from CentraleSupelec (Paris) and the State University of Campinas (Unicamp), where I focused my studies on AI and Optimization.

My experience spans diverse industrial contexts, from optimizing labor flexibility at Amazon in Luxembourg to automating hardware fault detection for Motorola at the Eldorado Institute. I also have a background in high-volume data integration and simulation, having worked with FlexSim to automate data imports and evaluate predictive frameworks to accelerate team adoption.

I work primarily with Python, SQL, and AWS, focusing on delivering transparent and actionable insights to stakeholders. I am fluent in English and French and am driven by the challenge of connecting technical infrastructure with efficient business operations.

Aprix

Associate Machine Learning Engineer - -

Full-time · Brazil (Remote)

  • Corrected a major revenue overestimation blind spot and enabled accurate quarter-over-quarter financial projections by deploying an end-to-end ML pipeline (Logistic Regression, Pipedrive). This solution replaced non-audited sales assumptions with data-driven win probabilities for active deals, supported by automated CI/CD workflows.

Working on the Governance and AI squad, building end-to-end AI and predictive solutions for internal teams.

Apprenticeship · Brazil (Remote)

  • Cut incident triage latency by 5 to 10 minutes per ticket for the Customer Support team, preventing SLA-driven financial losses with enterprise clients, by automating (n8n) the incident routing pipeline to ingest OTRS tickets, extract relevant client context, trigger real-time Discord alerts to stakeholders, and auto-generate fully detailed Kanban cards for immediate developer action.
  • Saved 3 hours per week in manual audits and prevented escalation delays by engineering a proactive governance bot (n8n) that automatically flags customer requests unanswered for 7 or more days.
  • Improved planning under uncertainty across business units by replacing subjective deadline-risk discussions with probabilistic completion scenarios, through a Monte Carlo forecasting engine with automated data ingestion and standardized management reporting.

Aprix is a SaaS company providing AI-driven pricing solutions for major industries in Latin America. Our technology helps large-scale businesses optimize pricing strategies and operational efficiency through scalable data products.

Business Intelligence Engineer Intern - -

Internship · Luxembourg (On-site)

  • Led end-to-end research and proof-of-concept in Amazon EU Supply Chain (middle-mile) to improve short-term labor planning guardrails for Sort Centers over 24-hour and 48-hour horizons.
  • Designed and validated predictive approaches under temporal dependencies, censored outcomes, class imbalance, and site-specific behavior using SQL-based data extraction and Python feature engineering.
  • Built and evaluated ML pipelines in AWS SageMaker Studio against operational heuristics and observed a 27.4% uplift over baseline for same-day forecasting across 10 UK Sort Centers.
  • Partnered with BI, Science, and Operations stakeholders through recurring technical and business reviews to translate model behavior into production-readiness trade-offs.

Instituto de Pesquisas Eldorado

Data Scientist Intern - -

Internship · Campinas, São Paulo, Brazil (Remote)

  • Optimized analysts' time and resources by 27% and improved battery fault-detection precision to 73% by replacing legacy rule-based heuristics with an end-to-end ML approach in a Motorola-funded R&D project.
  • Leveraged interpretable ML techniques (SHAP) to uncover hidden diagnostic patterns and expand expert manual criteria with data-driven insights.

Instituto de Pesquisas Eldorado is one of Latin America's premier R&D institutes (1,600+ engineers), partnering with global tech leaders such as Motorola to develop software, AI, and Industry 4.0 solutions.
