- Java Spring Boot expertise: building APIs, dependency injection, validation, error handling, and performance tuning.
- GraphQL proficiency: schema design, resolvers, federation/composition patterns (where applicable), query performance (N+1 mitigation, caching), and API governance/versioning strategy.
- REST proficiency: OpenAPI-style contract design, pagination/filtering, idempotency, backward compatibility, and consumer-driven API evolution.
- OIDC/OAuth2: hands-on implementation with JWTs, refresh/access token flows, scopes/claims, secure session patterns, and least-privilege access control.
- AWS experience (hands-on): designing, deploying, and operating cloud-native applications; strong understanding of IAM, networking basics, and operational tooling (logs/metrics/alarms).

- Strong Git practices, automated testing (unit/integration/contract/e2e), code quality gates, and release confidence practices (feature flags, progressive rollout where applicable).
- AI-assisted engineering (MUST):
- Demonstrated proficiency using Claude Code and/or GitHub Copilot to accelerate development, debugging, refactoring, test generation, and documentation—while ensuring correctness, security, and maintainability (e.g., validating outputs, avoiding sensitive data leakage, and adhering to team standards).
Preferred qualifications, capabilities, and skills
- Infrastructure as Code (Terraform/CloudFormation/CDK) and deployment automation patterns.
- Containerization and orchestration experience (Docker, ECS/EKS) depending on platform direction.
- Advanced security practices: threat modeling, OWASP Top 10 mitigation, secrets management, dependency hygiene.
