• Demonstrable experience creating detailed technical architecture documentation (HLD, LLD, network diagrams).
• Exceptional communication and presentation skills, with the ability to articulate complex technical concepts to senior leadership and technical teams.
• Strategic problem-solving skills with a proven ability to manage technical designs, risks, and project deliverables.
