Experience and education
Scientific Initiation Fellow in Artificial Intelligence
Applied conversational-AI research for searching, retrieving and analyzing intellectual-property assets, combining distributed applications and response evaluation.
- Integration across Java/Spring Boot, Python/FastAPI and Angular.
- RAG pipelines, BM25, embeddings, prompts and LLM provider adapters.
- Experiments with evaluation datasets and relevance, faithfulness and match metrics.
Software Quality and Testing at LEDS
Volunteer participation in a real software project, covering functional testing, requirements validation, defect investigation, test-data preparation and evidence documentation.
- Audit covering 88 considered tests and 87 recorded evidence items.
- 78 tests passed, 8 failed and 1 was inconclusive.
- Direct coverage of 14 of 28 functional requirements; 5 were blocked.
Income Predictor (Undergraduate Capstone)
Data product using PNAD Continua microdata, feature engineering, comparisons across econometric and machine-learning models, a FastAPI API and a React interface.
- Hybrid model with approximately 0.49 R² on the original income scale.
- Documented preparation, training, evaluation and inference pipeline.
