Architecture Practice & Domains

Architecture is the deliberate design of boundaries, relationships, and contracts. My practice addresses the lifecycle of complex systems across six interconnected domains.

Integration Mesh & Gateway

Contract-first gateway, rate limiting, token translation, and schema validation.

Architectural Responsibilities:
  • Mutual TLS / Auth mediation
  • Rate-limiting & throttling
  • Protocol translation (REST/GraphQL/gRPC)
  • Distributed telemetry injection
Contract Topology Links:

Orthogonal topology illustrating the flow from client experience layers through the integration gateway into distributed compute, event streaming, AI orchestration, and enterprise platform backbones.

Text alternative for screen readers: Interactive diagram connecting Experience layer to Integration Mesh, which distributes requests to Cloud Compute, Event Mesh, and AI Orchestrator, backed by Data tier and Enterprise Salesforce Platforms.

Domain Index

Core Domains of Practice

Detailed breakdown of concerns, architectural patterns, and systemic governance for each discipline.

DOMAIN 01

Experience Architecture

Bridging human intent and high-performance frontend runtimes

Treating frontend architecture as a distributed systems client: modular state machines, headless design systems, predictable caching boundaries, and accessible micro-frontends.

Critical Architectural Concerns:
  • State composition & normalization
  • Design token contracts & accessibility
  • Sub-second First Input Delay & zero CLS
  • Offline resilience & optimistic updates
Canonical Architecture Patterns:
Headless UI PrimitivesBFF (Backend-for-Frontend) AggregationComponent Islands & Selective HydrationStrict Tokenized Theming
DOMAIN 02

Enterprise Architecture

Governing systemic coherence across organizational boundaries

Aligning business capability roadmaps with evolvable system boundaries, legacy modernizations, and cross-functional governance frameworks.

Critical Architectural Concerns:
  • Domain-driven boundary decomposition
  • Technical debt remediation & migration paths
  • Security compliance & least privilege
  • Developer productivity & governance standards
Canonical Architecture Patterns:

DOMAIN 03

Integration & API Topology

Contract-first decoupling and robust systemic communication

Establishing deterministic communication protocols, schema governance, API gateways, and rate-limiting envelopes across heterogeneous platforms.

Critical Architectural Concerns:
  • Contract stability & backwards compatibility
  • Idempotency & distributed transactions
  • Rate-limiting & graceful backoff
  • Multi-tenant API mediation
Canonical Architecture Patterns:

DOMAIN 04

Event-Driven Architecture

Asynchronous resilience and distributed operational flow

Decoupling producer and consumer lifecycles via event brokers, log-based pub/sub architectures, and transactional message pipelines.

Critical Architectural Concerns:
  • Message ordering & deduplication
  • Dead letter queues & replay mechanics
  • Event schema evolution & deprecation
  • Observability across asynchronous traces
Canonical Architecture Patterns:
Pub/Sub Broker TopologyEvent Sourcing & CQRSDead Letter Queue (DLQ) HealingCompensating Transactions / Saga
DOMAIN 05

Platform & Salesforce Engineering

Extending enterprise platforms with modern engineering rigor

Treating enterprise platforms such as Salesforce not as closed black boxes, but as governed nodes integrated into modern CI/CD, event streams, and decoupled user experiences.

Critical Architectural Concerns:
  • Governor limit defense & query optimization
  • Bi-directional data synchronization
  • Decoupled Lightning Web Components (LWC)
  • Enterprise release pipelines & test suites
Canonical Architecture Patterns:

DOMAIN 06

AI-Augmented Systems

Grounded intelligence embedded within deterministic boundaries

Integrating generative AI and retrieval-augmented systems with guardrails, strict context boundaries, and deterministic enterprise schemas.

Critical Architectural Concerns:
  • Grounding & context-window budgeting
  • Hallucination mitigation via schema enforcement
  • Data sovereignty, privacy & tenant isolation
  • Latency budgeting & streaming ergonomics
