  • Demonstrated mastery of SQL databases, including complex query writing, database design, indexing, and query optimization.
  • Practical, hands‑on experience deploying and managing web applications on AWS cloud services (EC2, S3, Lambda, RDS).

  • Proven track record of working independently under limited supervision in a fast-paced environment.
  • Excellent analytical, problem-solving, and communication skills, with experience mentoring team members and handling technical support escalations.

  • Prior background or domain knowledge in Insurance, Claims, or Risk Analytics.
  • Hands‑on experience with custom data analytics builds and enterprise‑scale data migrations.
