"Explain This Code" Tutor (Socratic)

Explains unfamiliar code at chosen depth using the Socratic method — great for learning code you must maintain.

Walk the execution path step by step with line refs; for each non-obvious

End with: likely bug risks in this exact code, an interview-style hard question

System Design Interview / Real Design Partner

Produces a full design doc (requirements, capacity, API, data model, bottlenecks, trade-offs) and plays devil's advocate. Works for interviews and real projects.

ADR (Architecture Decision Record) Drafter

Turns an architectural choice into a concise ADR with context, options, trade-offs, and consequences — the artifact teams actually need later.

Distributed Systems Trade-off Analyst

For hard consistency/availability choices (CAP/PACELC, transactions, ordering) — produces requirement-driven decisions instead of buzzwords.

API-First / Schema-First Design Facilitator

Forces contract design before implementation, with evolution/versioning rules and consumer review — prevents costly API mistakes.

Multi-Tenancy Architecture Selector

Selects and details an isolation model (shared DB / schema per tenant / DB per tenant) against real requirements, including noisy-neighbor and backup isolation.

Event-Driven / CQRS / Saga Designer

Designs reliable event flows (Kafka/RabbitMQ/EventBridge): contracts, ordering, duplicates, sagas, and read models — including when NOT to use events.

Caching Architecture Advisor

Designs layered caching with explicit invalidation and consistency contracts — the hardest part of real systems.

Rate Limiting, Quota & Throttling Designer

Designs limiters (per-user/IP/tenant/API key), algorithm choice, and 429 contracts — including distributed counters and fairness.

File Upload / Media Pipeline Architect

Designs reliable uploads for large files with virus scanning, image/video processing, and storage lifecycle.

Search & Recommendation System Designer

Designs search (ES/OpenSearch/vector/hybrid) with relevance tuning pipelines — includes ranking eval and zero-result handling.

RAG / LLM-Application Architect

Designs a production retrieval-augmented generation system: chunking, embedding, hybrid retrieval, reranking, evaluation, and guardrails. (LLM-native dev category.)

LLM Evaluation / Hallucination Mitigation Planner

Builds an eval harness for LLM features: golden sets, metrics, red-team cases, and CI regression gates for prompts/chains.

Observability/SLO Architect

Defines SLOs, error budgets, alerting, and dashboards for a service from user journeys — symptom-based alerting, not noise.

Cost Optimization / FinOps Engineer

Finds and prioritizes cloud/infra spend reductions with risk and engineering cost.

Migration to the Cloud / Between Clouds Planner

Sequences a migration with risk control: inventory, patterns, data movement, cutover rehearsals, and rollback.

Security Architecture / Threat Modeler (STRIDE)

Runs STRIDE on a feature/architecture before building: trust zones, abuse cases, and mitigations mapped to controls.
