Oct 1, 2025October 2025: Focused on stabilizing deployment pipelines for Vizzuality/tnc-blue-carbon-cost-tool by injecting S3_BUCKET_NAME into the API image build. This enables CI-driven deployments to S3 by ensuring required bucket access during Docker builds, reducing environment drift and manual configuration. No major bugs fixed this month; primary work centered on pipeline reliability and preparatory work for upcoming features. Overall, improved deployment reliability, reduced time-to-production, and clearer alignment between CI needs and infrastructure configuration.

May 1, 2025May 2025 monthly summary for Vizzuality/tnc-blue-carbon-cost-tool: Delivered key features that improve project creation workflow and role-based access, fixed critical testing instability, and increased overall velocity and business value. Key features delivered: - Dynamic Project Form for Creation and Update: introduces a dynamic UI for creating/updating projects with API-driven calculations; new components for fields and styling. (Commit: c48ff7b57fc1b2d830830a8c2c7c31ca5c3ddc8d) - User Role Migration and Back Office UI Rename: refactors user role from PARTNER to USER across the application; updates default roles vs access controls; renames the back office Projects tab to 'Project Scenarios'. (Commit: b8bd595f02d9a937f077c49fb9f4c019f7bc7163) - Testing Infrastructure Stability: skips integration tests for the 'Project Map' to bypass a failing test and aligns test expectations in 'Create Custom Projects - Setup' to reflect code changes. (Commit: 6d95ebb54f65c6201ef97013df6b9bf84e4630cd) Major bugs fixed: - Stabilized testing/integration workflow by applying controlled test skips and expectation adjustments to maintain delivery velocity while code evolves. Overall impact and accomplishments: - Improved data integrity and UX consistency through API-driven project calculations and clearer back-office navigation. - Stronger role-based access alignment across the platform, reducing ambiguity and onboarding friction. - Maintained delivery velocity and CI stability during active refactors and feature work. Technologies/skills demonstrated: - Frontend component design and dynamic forms (React), API-driven calculations, and modular UI components. - Role-based access control refinement and global navigation changes. - Testing strategy, CI stability, and test expectation management.

Apr 1, 2025April 2025 monthly summary for Vizzuality/tnc-blue-carbon-cost-tool: Delivered end-to-end backoffice-driven project provisioning, expanded and stabilized user uploads across API and backoffice, and strengthened deployment/testing reliability. Notable outcomes include the implementation of Create Projects from the backoffice task with new endpoints, services, tests and backoffice integration, plus a cross-cutting update to the user uploads feature across API and backoffice. Addressed critical stability and flow issues with fixes to the project creation flow from the back office, backoffice cookie parsing, and enhanced S3 bucket configuration with environment variable parsing and naming adjustments. UX and reliability improvements were introduced in the backoffice (loader indicators during file operations, improved error handling, and UI form fixes). Strengthened CI/CD and testing through adding an S3 bucket container to e2e tests workflow and docker-compose enhancements for API tests. Demonstrated capabilities: API/backend work (NestJS-like architecture), backoffice integration, test-driven development, Docker/Docker-Compose, and S3 storage configuration and governance, delivering measurable business value through faster backoffice provisioning, improved data integrity, and operational stability.
