  • Professional experience with TypeScript and AWS, including services such as S3, Lambda, RDS, SQS, or ECS.
  • Strong fundamentals in algorithms, data structures, and system design, applied in professional engineering work.
  • Experience serving as a technical lead, setting direction and standards while remaining hands-on.
