Unsupervised Vegetation Segmentation
Final undergraduate thesis at University of Brasilia applying DINOv3 Vision Transformers for species-level semantic segmentation of aerial vegetation imagery. Achieved 8.7% mIoU (52% of supervised ceiling) using GMM clustering with PCA dimensionality reduction. Built custom MetaStore experiment tracking system with content-addressable config hashing, hardware-aware ETAs, and nearest-config matching. Target application: biodiversity monitoring and species richness estimation. Enabled 100+ systematic parameter sweeps with reproducible workflows on FORTRESS dataset.
yazelix
Declarative terminal IDE integrating Yazi, Zellij, and Helix. Solves keybind conflicts, delivers identical environments via Determinate Nix + devenv, with blazingly fast ~0.5s launches.
auto-layout.yazi
Yazi plugin for automatic layout switching based on terminal dimensions. Actively maintained to support recent Yazi versions with thoughtful error checking and logging improvements.
About
Data engineer specializing in ETL pipelines for large-scale medical databases and building reproducible, declarative development environments. Currently working with Python, PostgreSQL, pgplsql, and modern shell scripting (Bash, Nushell) to transform healthcare data at scale. Passionate about developer productivity - created yazelix, a terminal IDE with 700+ GitHub stars that solves real workflow problems through Nix-based reproducible infrastructure. Background in computer vision and ML experiment tracking from undergraduate research applying DINOv3 Vision Transformers to biodiversity estimation.
