What I'm looking for

I'm looking to build and operate production AI and backend systems, working across machine learning, APIs, deployment, monitoring, and data infrastructure.

At the State Attorney General’s Office (PGE-SE), I build and support production AI for legal process classification. I improved a classification model from 34% to 92% accuracy through data quality improvements and feature engineering.

I work across the full ML lifecycle, from data preparation and model evaluation to FastAPI integration, deployment, monitoring, and production support. I also implemented CI/CD that cut release time by about 50% and structured logging that reduced diagnosis time from hours to minutes.

I’m developing a RAG system for legal documents using Qdrant, producing source-grounded summaries with document-level citations. My backend work includes REST APIs, C#/.NET services, RabbitMQ, MongoDB, SQL Server, MinIO, Docker, Harbor, and Portainer.

Outside production legal systems, I built an esports ETL pipeline processing 50,000+ records with Airflow and Spark, and a FastAPI video-platform API with OAuth2, JWT, PostgreSQL, and Cloudflare R2.
