Tiago Baptista developed and enhanced core features across the Checkmarx/ast-cli and Checkmarx/ast-visual-studio-extension repositories, focusing on risk management, state handling, and automation. He implemented dynamic state filtering and risk management commands, integrating Go-based CLI tools with backend APIs to improve project risk visibility and configuration reliability. Tiago introduced robust error handling, feature flag management, and environment-variable-driven configuration loading, supporting safer releases and faster diagnostics. His work included expanding test coverage, refining UI theming in XAML, and automating release pipelines with GitHub Actions. Using Go, C#, and CI/CD practices, Tiago delivered maintainable solutions that improved reliability and developer experience.

March 2025 Monthly Summary: Delivered key features across two projects, improved UI/UX, and expanded risk management capabilities, driving clearer risk visibility and configuration reliability. Features delivered include dynamic state filtering UI in the Checkmarx Visual Studio Extension, settings validation and UI enhancements, and Risk Management integration in the Checkmarx ast-cli (CLI command, API integration, and updated data models) with accompanying tests. Major bugs fixed include label and test-related fixes, mock wrapper naming adjustments, and test stability improvements (e.g., trivy-related fixes and test flow fixes). Overall impact: improved end-to-end risk analysis for projects, streamlined configuration validation, and strengthened test coverage; this supports faster, more reliable risk assessments and easier maintainability. Technologies/skills demonstrated: UI development patterns, API integration, data modeling/schema updates, test-driven development, and refactoring for readability.

February 2025 performance summary for Checkmarx product teams. Focused on stabilizing the CLI experience, improving state management across components, and accelerating delivery through automated release workflows. Delivered refined state handling in the ast-cli, enhanced vulnerability state support in the Visual Studio extension, and established end-to-end release automation for the production plugin. Key accomplishments span three repositories: - Checkmarx/ast-cli: Introduced State ID management with a state ID flag, supporting system or custom IDs; added tests; implemented state ID type changes to int and corresponding help updates; unified state constants via constantsStates; and added command help improvements. - jenkinsci/checkmarx-ast-scanner-plugin: Implemented Automated Release Pipeline using GitHub Actions to release the production plugin, including CI validation and Maven release steps. - Checkmarx/ast-visual-studio-extension: Added functionality to fetch security vulnerability states from the CLI, refactored State to SystemState for clarity, wired dynamic UI loading via StateManager, updated CLI commands, and replaced the cx.exe binary with a newer version. Major bugs fixed: reliability tests were stabilized with tightened expectations; extensive comment cleanup to reduce noise; policy evaluation skip behavior bug fixed and tests updated; general fixes across the batch; and help text adjustments to reflect state ID changes. Overall impact: improved reliability and user guidance across CLI and VS extension, faster and safer release processes, and clearer state semantics that reduce risk in security triage work. Business value includes faster time-to-prod releases, fewer flaky tests, and more predictable security state handling. Technologies/skills demonstrated: CLI design and testing, code refactoring for clarity (State/SystemState), test strategy and reliability engineering, centralized constants management, GitHub Actions and Maven-based release pipelines, Visual Studio extension integration, and binary asset management.

January 2025: Delivered a series of reliability and quality improvements across two repos (Checkmarx/ast-visual-studio-extension and Checkmarx/ast-cli). Strengthened test coverage and UI test infrastructure, improved UI theming consistency, refined API accessibility, and added precise code-coverage instrumentation. Implemented an exponential backoff retry mechanism for the CLI to improve resilience against transient API errors. These changes reduce risk in production, improve maintainability, and accelerate future development.
