Aug 1, 2025

August 2025 (Vizzuality/amazonia-360): Delivered key features that strengthen CI/CD, dev ergonomics, and observability, while making authentication and locale handling more robust. Implemented Webshot Test Automation CI/CD workflow with Node.js setup, dependency installation, Chromium for end-to-end tests, and an optional disable toggle to ensure safe rollout. Added Dev Environment and Env Management utilities to split environment vars into per-component .env files, with updated dev dependencies to support env tooling. Enhanced observability through Webshot and Report services by adding detailed network log headers and verbose error logging. Improved Webshot locale handling by forcing Accept-Language headers and removing a default language header to respect user settings. Simplified deployment setup by adding a default server port. Updated OpenAPI branding to reflect Amazonia360 without changing functionality. These changes collectively improve release reliability, developer experience, and debugging efficiency, enabling faster delivery of features and more predictable deployments.

Jun 1, 2025

June 2025 summary for Vizzuality/tnc-blue-carbon-cost-tool: Delivered a key feature enhancement to cost modeling by updating the total base cost calculation to divide by baseSize, improving cost accuracy across size-based scenarios. This change aligns pricing with real-world scaling and reduces the risk of misestimation in larger projects. Added a new integration test scaffold for Restoration Mangroves Bahamas to validate end-to-end costs (test file created; currently skipped), establishing groundwork for future CI validation. No major bugs recorded this month. Overall impact: more reliable cost projections, better support for Mangroves restoration scenarios, and strengthened foundation for data-driven decision making. Technologies/skills demonstrated: pricing logic refactor (baseSize-based scaling), test scaffolding, and Git-based change management for core pricing tools.
