Director-scope Platform & Enterprise Architecture (TOGAF) — Principal Software Engineer, Sr. Manager II
I lead platform and enterprise architecture programs at Fortune-1 scale — managing staff and solutions architects alongside engineering managers, tech leads, and developers. My organization spans 45+ engineers, architects, and managers; 80+ engineers across eight cross-functional teams; and systems consumed by 300+ enterprise applications at 50K+ TPS and 99.99% uptime. Recent outcomes include $5.1M+ annual cloud savings (FinOps + architecture), $1.2M mainframe retirement, and governed GenAI/agentic platforms in production.
I am a player-coach for architects — I set enterprise architecture direction, ADR standards, and review-board bar; I coach 15+ senior and staff engineers into architecture and leadership roles. The repositories below are an open Enterprise Platform Reference Architecture: runnable ADRs, system design, CI, and one-command local runs — the reference patterns I expect architects on my teams to deliver, published for regulated industries (banking, healthcare, insurance, retail).

| Dimension | Scale |
|---|---|
| Architect org | Manage staff and solutions architects plus engineering managers and tech leads — not only IC developers |
| Organization | 45+ engineers, architects, and managers; 8 cross-functional teams (~80 engineers) |
| Talent | Coach and develop 15+ senior/staff engineers into architecture and leadership; raise architecture bar across domains |
| Business outcomes | $5.1M+ annual cloud savings · $1.2M mainframe OPEX eliminated · ~50% deployment frequency improvement |
| Platform scale | 50K+ TPS · 99.99% uptime · 300+ consuming applications |
| Programs | Merchandising cost/price/negotiations · supply chain · space · analytics · data & AI platform modernization |
| Governance | ADRs · architecture review boards · SLO/SLI standards · Area Tech Review Council (50+ major initiatives) |
Each repo reframes a domain I owned at scale as a domain-agnostic capability — with ADRs, system-design docs, tests, CI, and Docker Compose. The same patterns map to banking, healthcare, asset management, retail, and product companies.
| Repository | Stack | What it proves |
|---|---|---|
| payments-modernization-platform | Java / Spring | Modernize a legacy core with zero big-bang: Strangler Fig, Anti-Corruption Layer, CDC, CQRS + event sourcing, orchestration SAGA + compensation, canary |
| agentic-rag-engine | Python / FastAPI | Production RAG: hybrid retrieval (vector + BM25 + RRF), reranking, grounded answers with guardrails, LangGraph agent, eval harness |
| governed-mcp-gateway | Java + Python | Governed agentic AI: MCP servers, policy engine, human-in-the-loop, hash-chained audit, PCI/HIPAA/retail redaction |
| pricing-orchestration | Java / Spring | MACH + DDD pricing platform: rules engine, workflow orchestration, choreography SAGA, canary |
| streaming-lakehouse-platform | Python / PySpark | Medallion lakehouse on Delta Lake: Kafka + CDC, CQRS read models, feature store, data-quality quarantine |
A distributed transaction with compensation is a payment settlement (banking), a claims adjudication (healthcare), a trade/position update (asset management), and a price-change rollout (retail). Same SAGA. Same CQRS. Different nouns.
Five retail subdomains — each repo is one technology pillar, wired as one coherent platform story.
| # | Repository | Stack | Capability |
|---|---|---|---|
| 1 | supplier-golden-record-platform | Kafka · Cassandra | Multi-source supplier MDM → golden record + CDC |
| 2 | location-reference-cache | Redis · RabbitMQ | Location read tier — read-through cache, event invalidation |
| 3 | supplier-negotiation-observability | Elasticsearch · Logstash | Negotiation observability — correlation IDs, regulated redaction, stalled-deal SLOs |
| 4 | microspace-planogram-platform | Airflow · Flink · Cassandra | Planogram pipelines — item × club × fixture at scale |
| 5 | item-cost-ledger-platform | Temporal · Kafka · CQRS | Item cost ledger (keystone) — event sourcing, GraphQL + REST, OpenTelemetry + Grafana SLOs |
