Technical challenges in data preservation and security were addressed through the formulation of robust automation, backup, and recovery protocols. Optimization of existing software systems was conducted to enhance both performance and scalability, with contributions to project scope estimation during the planning phases. Database design and implementation utilizing SQL Server and MongoDB were key activities, alongside the integration of object-oriented design methods in software projects. Experience extends to designing software for real-time operating systems including QNX and ThreadX, aligning technical expertise with operational requirements.
