Cut AI/LLM spend without degrading quality — model tiering and cascade routing, Batch API offloading, context and output-token discipline, reasoning-effort tuning, and per-feature cost attribution. Outputs a per-feature cost baseline, a model routing plan…

Implement data observability across the five pillars — freshness, volume, schema, distribution, lineage — with anomaly detection on pipelines and lineage-driven incident triage. Outputs a tiered coverage plan, monitor configurations, alert routing rules, an…

Build production vision and document-understanding pipelines on the Claude API — image inputs, PDF processing, structured extraction, and multimodal RAG. Outputs ingestion-path decisions, resolution and token budgets, extraction schemas, evaluation plans, and…

Design and implement graph analytics — property graph vs RDF modeling, engine selection (Neo4j, Memgraph, Neptune, Spark GraphFrames), and algorithm-to-business-question mapping. Outputs graph schema, Cypher queries, batch algorithm pipelines, and GraphRAG…

Secure webhook receiving endpoints against spoofing, replay, duplicate processing, and overload. Outputs HMAC verification code with timing-safe compares, timestamp and idempotency defenses, secret rotation plans, queue-backed 2xx-fast handler architecture,…

Design and run chaos engineering experiments against infrastructure — steady-state hypotheses, blast-radius control, and staged promotion from dev to production. Outputs experiment specs (Chaos Mesh, LitmusChaos, AWS FIS), abort conditions, game-day runbooks,…

Design a semantic layer that defines every business metric once and serves it consistently to BI tools, spreadsheets, and AI agents. Outputs metric specs (dbt MetricFlow or Cube), a platform decision record, a governance and ownership model, and integration…

Build and keep alive a service catalog / internal developer portal — Backstage or a commercial IDP — with enforced ownership, on-call mapping, and maturity scorecards. Outputs catalog schema (catalog-info.yaml), ownership model, scorecard definitions, CI…

Write Ansible playbooks for server provisioning, configuration management, and application deployment. Outputs idempotent plays with roles, handlers, vault-encrypted secrets, and inventory management.

Implement blue-green deployment strategy for zero-downtime releases with instant rollback capability. Outputs infrastructure configuration, traffic switching scripts, health check validation, and rollback procedures.

Implement canary release strategy for gradual traffic shifting with automated promotion and rollback. Outputs traffic weight configuration, metric-based promotion gates, and rollback triggers.

Implement distributed tracing across microservices using OpenTelemetry. Outputs trace instrumentation, context propagation, sampling configuration, Jaeger/Tempo integration, and trace-based debugging workflows.

Design authentication and authorization architecture covering JWT, OAuth2, RBAC, session management, and MFA. Outputs auth flow diagrams, token strategy, permission models, and implementation patterns.

Implement event sourcing pattern where state is derived from an immutable sequence of events. Outputs event store design, aggregate patterns, projection builders, and command/event handlers.

Design systems that continue operating with reduced functionality when components fail. Outputs fallback strategies, partial failure handling, feature toggles, and user-facing degraded-mode experiences.

Design reliable webhook systems with retries, idempotency, and signature verification. Outputs webhook endpoints, delivery guarantees, and security patterns.
