About me

Hi, I'm Javier — a Software Development Technician (Universidad Gastón Dachary, 2025) working out of Córdoba, Argentina. My path into tech started 20+ years ago in IT support and hardware maintenance; later I spent several years running a farm, where a bad call costs you a season, not a rollback.

Over the past year I've focused on building complete, end-to-end projects: backends in Java/Spring, Go and Rust; React frontends; ML pipelines with inference at the edge; and developer tooling — multi-agent AI code review, starter templates for new projects, and automated setup for fresh dev machines. Every project pushes me into a new stack.

• Understand the problem before writing code. I take the time to read, discuss and map out what I'm solving before the first line.
• Technical decisions with the tradeoff spelled out. Every choice has a cost; I pick deliberately and can explain why.

• Backend: Java/Spring Boot, Go (Gin), Rust (Axum/Tokio), Python (FastAPI)
• Frontend: React, Next.js, Vite, Mantine, Zustand, Zod, React Flow
• Industrial edge: Modbus TCP/RTU, MQTT, local ML inference with ONNX
• ML pipelines: training in Python, inference in Rust with parity tests, SHAP for explainability
• AI tooling: MCP servers, multi-agent systems, SAST/SCA integration (Semgrep, Trivy, Gitleaks)
• DevOps: Docker, GitLab CI, GitHub Actions
• Spec-Driven Development with OpenSpec, conventional commits
