• Designing integration with Hardware Security Modules (HSMs) to enable secure key management and code signing.
• Recommending suitable technologies, infrastructure components, and deployment models.
• Producing a detailed solution proposal, including architecture diagrams, implementation roadmap, and technical recommendations.
• Preparing a realistic cost estimate covering implementation, licensing (where applicable), infrastructure, and knowledge transfer activities.
• Providing recommendations for governance, operational processes, and long-term maintenance.
