Jan 1, 2025January 2025: Delivered two major feature sets in ToposInstitute/CatColab, advancing both visualization and simulation control, with a focus on business value and maintainability. Graph enhancements introduced delayed-link visuals for arrows with +/− indicators, improving clarity of relationship flows and reducing interpretation errors. Decapodes simulations gained a new duration parameter across data structures, frontend configuration, and execution logic, enabling precise temporal control for experiments. A CSS delay styling fix and a code-quality pass (lint/formatter) were completed to solidify the UI polish and maintainability. Overall impact: richer, more expressive graph analytics and more configurable simulations, enabling faster, more reliable experimentation and decision-making. Technologies/skills demonstrated: CSS/SVG rendering, TypeScript typings, data-structure integration, UI/frontend iteration, and CI-quality practices.
