Frontend (React) strong: * React + TypeScript: component design, hooks, state management, form handling, routing. * UI quality: accessibility basics, performance, error boundaries, loading states. * API integration: robust data fetching/caching, pagination/infinite scroll, optimistic updates, consistent client-side error handling. * Testing: React Testing Library; e2e basics with Cypress/Playwright. AWS and runtime strong hands-on: * Identity and access: IAM roles/policies, least privilege, cross-account basics, secrets management patterns. * Infrastructure as Code: Terraform or CloudFormation/CDK (one strongly); environment promotion strategy (dev/test/prod), parameterization, drift awareness. * Containerization: Docker images, health checks, resource limits, multi-stage builds. * Core AWS fluency (expected to have shipped production workloads): * Compute: ECS and EC2 autoscaling concepts * Networking: VPC, subnets, security groups, NACL basics, private vs public connectivity * Storage/data: S3; RDS/Aurora Postgress fundamentals; DynamoDB awareness even if not primary * Integration: SQS/SNS * Observability: Splunk and CloudWatch logs/metrics/alarms, log retention, dashboards Data and persistence advanced: * SQL: indexes, query plans, joins, transaction semantics; can tune slow query issues end-to-end (app + DB). * Migrations: Flyway/Liquibase discipline; zero-downtime schema evolution patterns. * Caching: Redis (ElastiCache) usage patterns, TTL design, cache stampede prevention, invalidation strategy. Observability and production excellence expert: * Structured logging with correlation IDs; PII redaction discipline. * Metrics + SLO thinking: latency/error rate saturation signals; actionable alarms (not noise). * Tracing: Open Telemetry * Operability: runbooks, on-call readiness, meaningful postmortems with preventative actions. Testing and quality expert: * Backend: JUnit5, Mockito, Spring test slices, Test containers; contract tests (Pact) preferred for service-to-service APIs. * Performance: basic load testing and interpreting results; capacity and tuning recommendations. * Security: SAST/dependency scans; remediates CVEs quickly and safely. Security (practical, senior-level) non-negotiable: * AuthZ: RBAC/ABAC concepts; least privilege both in app and AWS IAM. * Secrets: no secrets in code/logs; uses managed secrets and rotation patterns. Additional Skills: * Full Stack Java Developer with Spring Batch, AWS(ECS, S3, Lambda), Infrastructure, Aurora Postgres DB, Kafka excellent communication.
