  • Develop secure, production-grade code and enforce engineering standards through thorough code reviews.
  • Build highly available and scalable services with strong operational excellence, including reliability, performance, and cost awareness.
  • Implement and govern authentication/authorization using OIDC/OAuth2, token validation, and service-to-service security patterns.

  • React expertise: modern patterns, TypeScript, state management, component design systems, and performance optimization.
  • Java Spring Boot expertise: building APIs, dependency injection, validation, error handling, and performance tuning.
  • GraphQL proficiency: schema design, resolvers, federation patterns, query performance (N+1 mitigation, caching), and API governance.
  • REST proficiency: OpenAPI-style contract design, pagination, idempotency, and backward compatibility.
  • AWS experience: designing, deploying, and operating cloud-native applications; IAM, networking, and operational tooling.
  • Data layer expertise: AWS Aurora PostgreSQL (advanced SQL, indexing, migrations) and AWS Neptune (Gremlin, graph modeling).
  • Event-driven systems: AWS Kafka (MSK) topics/partitions, consumer groups, schema evolution, and operational monitoring.
  • AI-assisted engineering: demonstrated proficiency using Claude Code and/or GitHub Copilot for development, debugging, and refactoring.

Preferred Skills

  • Infrastructure as Code (Terraform/CloudFormation/CDK) and containerization (Docker, ECS/EKS).
  • Advanced security practices: threat modeling, OWASP Top 10 mitigation, and secrets management.
