PROFILE
Sina Zel Taat
Sina contributed to the Blueprints-org/blueprints repository by developing and refining structural engineering features aligned with Eurocode standards. Over five months, Sina implemented new calculation formulas, enhanced cross-section geometry processing, and improved code maintainability through targeted refactoring. Using Python and NumPy, Sina introduced abstract base classes for formula evaluation, standardized precision in geometric computations, and expanded test coverage for steel profiles. The work included optimizing CI/CD workflows with Makefile automation and GitHub Actions, resulting in more reliable releases. Sina’s approach emphasized numerical stability, code clarity, and developer ergonomics, delivering robust backend functionality and higher-quality engineering calculations for the project.

Sep 1, 2025September 2025 monthly summary for Blueprints-org/blueprints: Delivered a precision and readability enhancement to cross-section calculations, improving numerical stability and downstream reliability. Implemented an ACCURACY constant in CrossSection to define polygon coordinate rounding, and refactored point-generation in HexagonalCrossSection and RectangularCrossSection to apply rounding once to the entire coordinates array, simplifying NumPy handling and reducing floating-point issues. These changes underpin higher-quality geometry processing with cleaner code and better maintainability.

Jul 1, 2025Summary for 2025-07: Delivered critical updates to structural analysis capabilities and developer ergonomics in the Blueprints project. Key features include updating the Z-profile compression check to EN 1993-5:2007 with aligned tests, imports, class names, and method parameters; exposing standard steel profile types for easy import to streamline usage for developers; plotting improvements for steel cross-sections with pre-calculated section properties and corrected moments of inertia display; and a revamped testing pipeline with parallel execution, slow-test labeling, a lightweight test target, and mocks for plotting tests. These changes improve compliance with engineering standards, accelerate feature delivery, and enhance CI reliability and developer productivity.
