  • Make platform-level design decisions on deployment models (cloud, hybrid, on-premise), consensus mechanisms, and security protocols

  • Evaluate and select appropriate blockchain platforms, protocols, and tools based on client requirements and technical feasibility

  • Ensure solutions adhere to cryptographic security standards, regulatory compliance requirements, and industry best practices

  • Collaborate with delivery teams, developers, and DevOps engineers to ensure architectures are buildable, testable, and operable

  • Create and maintain technical documentation including architecture diagrams, system specifications, and integration guides

  • Identify and escalate architectural risks, technical dependencies, and performance bottlenecks

  • Mentor junior architects and developers on architectural patterns, blockchain best practices, and secure coding principles
