Qualifications

• 10+ years in application development or cloud architecture with a strong focus on microservices.
• Proven hands-on experience designing and implementing end-to-end solutions on AWS -

• Strong Node.js expertise building production REST APIs with NestJS.
• Experience with PostgreSQL and caching patterns in a cloud environment.
• Experience implementing authentication and authorization using Cognito, Okta, JWTs, or IAM.
