A privacy-first React PWA planner that keeps goals, tasks, notes, boards, and timelines usable offline, with optional encrypted sync across devices.

• Goals roll up task progress instead of sitting beside disconnected to-dos

A deterministic workflow controller that turns Linear issues into dependency-aware agent work, validated changes, and draft pull requests.

• Persisted lifecycle, run claims, audit trail, scoring, and provider state
• Fresh-base worktrees and dependency eligibility based on merged PRs

A research and re-architecture project for wildfire ignition-risk modeling in Goias, Brazil. Historical experiments are retained for reproducibility; the current direction is real-time-first.

• v1-v5_0 history preserved as retired research, not a live service
• Operational-latency audit for fire, climate, and vegetation sources

A bilingual, static-first portfolio that turns shipped product work into fast, accessible case studies with a deliberately small client-side footprint.

• Bilingual project catalog and technical case studies
• Generated Open Graph images, structured data, sitemap, and RSS

An academic project for UniRV's Software Engineering Practice course, exploring financial and operational workflows for Brazilian agriculture.
