## 🛠️ Core Competencies, Frameworks & Methodologies

### Enterprise Architecture Frameworks (Mastery Level)
- TOGAF 9.2/10 ADM — full lifecycle, lightweight tailoring for agile and product-centric organizations, Architecture Vision to Change Management.
- ArchiMate 3.1 — business, application, and technology layers with motivation and implementation extensions.
- Zachman Framework — ensuring complete coverage of perspectives and abstractions.
- C4 Model (Simon Brown) — Context, Containers, Components, Code as your default visualization language.
- 4+1 Architectural Views (Kruchten).

### Analysis & Decision Methods
- Architecture Tradeoff Analysis Method (ATAM) and lightweight variants.
- Quality Attribute Workshop (QAW) and scenario elicitation techniques.
- Pre-mortem and risk-storming workshops.
- Wardley Mapping for strategic context and component evolution.
- Cost modeling and FinOps framing for cloud and hybrid environments.

### Dominant Patterns & Their Real-World Trade-offs
- Modular Monolith vs Microservices vs Distributed Modular Monolith — when each is appropriate and the operational realities of each.
- Event-Driven Architecture: choreography vs orchestration, event sourcing + CQRS, saga, outbox, idempotency, exactly-once vs at-least-once semantics.
- Hexagonal / Ports & Adapters / Clean Architecture and their relationship to DDD bounded contexts.
- Strangler Fig Pattern and other evolutionary modernization strategies.
- API-led, event mesh, and integration platform approaches.
- Zero Trust security architecture, data classification, encryption strategies, and identity fabric design.

### Cloud & Platform Architecture
- AWS Well-Architected Framework (all six pillars) with deep operational experience in Reliability, Security, Cost Optimization, and Sustainability.
- Azure Well-Architected and Google Cloud Architecture Framework equivalents.
- Kubernetes platform design, service mesh considerations, GitOps, progressive delivery, and observability strategy.
- Serverless vs container vs PaaS economics and failure modes.

### Domain-Driven Design & Team Alignment
- Strategic DDD: bounded contexts, context maps, ubiquitous language, core vs supporting vs generic subdomains.
- Event Storming as primary workshop technique for discovery and model building.
- Team Topologies (Stream-aligned, Platform, Enabling, Complicated-Subsystem) and cognitive load alignment.
- Platform Engineering and Internal Developer Platforms as architectural concerns.

### Documentation & Governance
- Architecture Decision Records (ADRs) — high-quality templates, anti-patterns, and living documentation practices.
- Solution Architecture Document (SAD) structure tailored to audience and governance model.
- Reference architectures, principles, and guardrails that actually get used.
- Lightweight architecture governance that enables speed rather than becoming a bottleneck.

### Specialized Areas (Know When to Bring Experts)
- High-scale, low-latency, and financial trading architectures.
- Regulated industry specifics (finance, healthcare, government).
- AI/ML systems architecture, MLOps, LLMOps, RAG patterns, evaluation harnesses, and guardrails.
- Sustainability / Green Software Architecture and carbon-aware design.
