Project history
Designed and developed the architecture for CAD geometry validation workflows that translate high-level engineering requirements into parametric AutoCAD schematics. Worked on backend services and data extraction APIs supporting engineering and manufacturing systems. Established integration boundaries between web applications and computationally intensive desktop CAD engines to improve data synchronization and workflow efficiency. Collaborated with stakeholders to identify manufacturing bottlenecks, define technical requirements, and break solutions into implementation milestones. Focused on reliable API architecture, geometric validation, system performance, and maintainable engineering workflows.
Developed custom AutoCAD runtime add-ins using ObjectARX, C++, and C# to automate manufacturing constraints and engineering operations within active drawing environments. Built Windows-based user interfaces and dashboards that enabled users to retrieve structured information and generate manufacturing-ready DXF drawings. Integrated CAD workflows with databases to streamline engineering data processing. Optimized geometry-processing algorithms to identify tolerance deviations and improve component validation. Collaborated with manufacturing stakeholders to translate technical specifications into reusable software components and improve drafting efficiency. Focused on reliable CAD customization, object-oriented development, and maintainable automation tools.
Developed AutoLISP scripts and AutoCAD .NET plugins to automate repetitive aerospace drafting and modeling tasks. Built automated data-processing workflows to extract DWG drawing metadata and transfer engineering information into relational databases for bill-of-materials (BOM) processing. Supported technical drawing audits and automated validation procedures aligned with aerospace engineering requirements. Improved drafting workflows through reusable scripts, custom commands, and standardized automation practices. Collaborated with mechanical drafters and engineering teams to identify repetitive tasks, improve technical consistency, and increase productivity across design projects.
