1. Architecture and patterns (Core Architecture)

• Architectural approaches: In-depth understanding of microservice architecture (MSA), monoliths and their dissection, modular monoliths, CQRS and Event Sourcing patterns.
• Clean architecture: Confident application of SOLID principles, DDD (Domain-Driven Design), Hexagonal/Clean Architecture in practice, not just in theory.
• System integration: Designing interaction between services (synchronous via REST/gRPC and asynchronous).

2. Working with data and highload (Databases & Messaging)

• Advanced SQL/NoSQL: Ability to optimize complex queries, profile them (EXPLAIN ANALYZE), configure indexes (B-Tree, GiST, GIN), understand transaction isolation levels (ACID).
• Database scaling: Experience with replication (Master-Slave), sharding, and table partitioning.
• Asynchronous messaging: Confident work with message brokers (Kafka, RabbitMQ, Pulsar). Understanding delivery guarantees (At-least-once, Exactly-once), idempotency of handlers.
• Caching: Caching strategies (Cache-Aside, Write-Through) using Redis or Memcached, cache invalidation.

3. Infrastructure and DevOps (Infrastructure)

• Orchestration: Not just writing a Dockerfile, but understanding how applications work in Kubernetes (K8s) (concepts of Pods, Services, Deployments, ConfigMaps).
• CI/CD: Setting up and maintaining pipelines for automated testing and deployment (GitLab CI, GitHub Actions, Jenkins).
• Observability: Integration and work with logging (ELK/PLG), metrics (Prometheus + Grafana), and tracing (Jaeger/OpenTelemetry) for quick bug detection in production.

4. API design and security

• Protocols: Confident use of gRPC (ProtoBuf) for inter-service communication and GraphQL / REST for external clients.
• Security: Designing authorization at the microservices level (OAuth2, OIDC, JWT), understanding the concept of API Gateway (Kong, Envoy).

5. Soft Skills and Processes (Soft Skills)

• Soft Leadership: Conducting high-quality Code Review, mentoring juniors, ability to argue architectural decisions to the business and the team.
• Managing Uncertainty: Ability to work with incomplete or changing requirements, independently gather analytics on the task.
