  • Led zero-downtime authentication migration (AWS IAM to OAuth/JWT) across 1,000+ enterprise accounts, unblocking a 4-year compliance initiative with a 5-phase execution plan delivered in 2 quarters.
  • Restructured IAM permissions by analyzing 301 policies across 146 accounts, consolidating 16 billion+ combinations into a 3-role model (READ, EDIT, ADMIN) enabling 59.5 percent automated migration.
  • Built an AI-powered developer tool using Bedrock (Claude 3.5), RAG, and MCP with 56 integrated tools, cutting config troubleshooting from 2-4 hours to under 10 minutes and deflecting 30 percent of support tickets. Won internal hackathon.
  • Engineered Service-to-Service authentication using OAuth, navigating a platform constraint to compress delivery from 12 weeks to 4 weeks with Principal Engineer sign-off.
  • Resolved production concurrency bug in a high-throughput token service by implementing DynamoDB transactional uniqueness constraints, shipping 2 weeks before Fire TV launch with zero regressions.
  • Overhauled auth infrastructure: redesigned request path (ALB, CloudFront, WAF) cutting hops from 5 to 3 and latency by 18 percent; automated API lifecycle via Step Functions replacing 3-day manual workflows.
  • Shipped 10+ production RESTful APIs and a React-based admin console; managed operational reliability across 5+ services including a 24,785-item DynamoDB migration (100 percent success) and 50+ incident resolutions on-call.
