Jan 1, 2025January 2025 (2025-01) ADRIA.jl monthly summary: Delivered tangible business value by improving traceability, scenario-analysis readiness, and code quality across the repository. Implemented new outputs to show timesteps, enabling better traceability of simulations; extracted features from scenario specs to streamline analyses; consolidated and enhanced seed_corals! workflow with deployment tracking and recruit logging; expanded data visualization to cover all DHW scenarios and taxa visuals; and applied extensive code-formatting, linting, and cleanup to improve maintainability and developer velocity. Fixed critical bugs including variable naming that obscured usage, seeding overflow when space is insufficient, and an indexing bug in data structure access. These changes reduced risk of misinterpretation, improved stability, and lowered memory footprint through cache cleanup and micro-optimizations. Technologies/skills demonstrated include Julia language proficiency, code quality automation (linting, formatting, docstrings), feature extraction patterns, visualization integration, and documentation improvements.
