What I'm looking for

I’m seeking junior Java or Python backend, full-stack Java, integration, or automation roles. I prioritize remote work from Argentina and also consider opportunities in Paraná and Santa Fe city.

At SIGAP, a municipal system in production, I build full-stack features with Java 8, JSP/Servlets, JavaScript, Hibernate/JPA, and PostgreSQL/PostGIS. I developed an OpenLayers map with GeoJSON layers, spatial selection, viewport queries, and editing, integrated with work-order forms.

I also developed statistics covering lighting assets, electricity consumption, and invoice spending. I gather requirements directly from users, analyze the domain, and define solutions alongside another developer.

I developed invoice data extraction using Python, Ollama, and a local multimodal model, integrating it with Java through an API. I also deployed SIGAP-RCC automation to production using Python and Playwright, with validation, duplicate checks, and record verification.

My individual academic projects include Java 21, Spring Boot, MongoDB, Redis, FastAPI, and React. I’m studying programming at UTN Paraná and completed UTN Buenos Aires’ Diploma program in Artificial Intelligence.
