Biel Stela contributed to the Vizzuality/amazonia-360 repository by engineering robust backend features and data workflows that improved API reliability, data integrity, and deployment automation. He developed polygon-filtered metadata endpoints and H3 grid dataset update scripts using Python, FastAPI, and Polars, enabling region-specific queries and streamlined data ingestion. Biel refactored API structures for clearer data modeling, integrated OpenAI-powered content generation, and enhanced CI/CD pipelines with secure secret handling and dependency management. His work also included documentation improvements and infrastructure cleanup, supporting maintainability and onboarding. Across these efforts, Biel demonstrated depth in backend development, cloud deployment, and data engineering.

September 2025 performance-focused month for Vizzuality/amazonia-360. Focused on stabilizing tiling workflows, expanding grid capabilities, and tightening deployment/testing processes. Delivered concrete improvements to H3 grid generation, tiling APIs, and data synchronization, while addressing regression and cleanup tasks to reduce operational risk. Result: more accurate country coverage, faster tile rendering, a cleaner API surface, and streamlined deployment and testing workflows.

August 2025 milestone for Vizzuality/amazonia-360: Delivered two core features with measurable impact on performance, security, and data integrity. 1) API Dependency Upgrades and Zonal Stats Reader Params Fix: Upgraded core Python dependencies (polars, pydantic, ruff) and applied minor updates to others. Fixed zonal_stats.py to pass reader_params as a dictionary, improving performance, security, and compatibility. 2) H3 Grid Dataset Update Script: Added a Python script to merge new data from CSVs into H3 grid datasets, enhanced grid metadata with new columns, and added pre-processing validation to ensure directory structure integrity before processing.

December 2024: Implemented polygon-filtered metadata retrieval for the /meta endpoint in Vizzuality/amazonia-360, enabling dynamic min/max calculations based on polygon filters and area-specific metadata via GeoJSON features. Aligned API root path to /api/ and updated routing, data loading, and metadata processing to support region-based queries. Added a minor documentation polish (README trailing space removal) with no user-facing impact. Overall, this work improves data discovery accuracy, API consistency, and maintainability for region-focused analysis.
