  • Collaborate with product owners, analysts, and engineering teams to ensure alignment and consistency.
  • Evaluate new technologies, tools, and frameworks and advise leadership on adoption.
  • Produce architecture documentation, diagrams, and roadmaps using appropriate frameworks and tooling.
  • Contribute to solution reviews and ensure compliance with architectural guidelines and non-functional requirements.
