• Define application components, service boundaries, integration patterns, data flows, and technology choices.
• Establish architectural standards, reusable design patterns, coding guidelines, and engineering best practices.
• Prepare High-Level Design (HLD), Low-Level Design (LLD), architecture diagrams, sequence diagrams, and deployment views.
• Evaluate architectural trade-offs involving scalability, performance, maintainability, security, cost, and time to market.
2. Auth0, CIAM & Security Architecture
• Design and govern Auth0-based identity and access management solutions for customer-facing e-commerce platforms.
• Define authentication and authorization architecture using OAuth 2.0, OpenID Connect (OIDC), JWT, and SAML where applicable.
• Architect Single Sign-On (SSO), Multi-Factor Authentication (MFA), social login, enterprise federation, and Role-Based Access Control (RBAC).
• Define secure identity integration patterns for web applications, mobile applications, backend services, and third-party platforms.
• Establish token validation, session management, API security, identity lifecycle, and access control standards.
• Design secure customer identity journeys, including registration, login, account recovery, profile management, and identity federation.
• Collaborate with security and compliance teams to address identity risks, application vulnerabilities, and security requirements.
• Define secure integration patterns between Auth0, API gateways, microservices, and external identity providers.
3. E-commerce & Digital Commerce Architecture
• Design end-to-end architecture for B2B and B2C e-commerce platforms.
• Define integration strategies for product catalogs, pricing, promotions, carts, checkout, payments, orders, and customer profiles.
• Architect secure integrations with payment gateways, customer data platforms, CRM systems, and third-party commerce services.
• Evaluate and design headless commerce and API-first digital commerce solutions.
• Define reusable integration components and reference architectures to accelerate onboarding of multiple e-commerce clients or projects.
• Ensure architecture supports high transaction volumes, availability, extensibility, and seamless customer experiences.
4. API, Microservices & Integration Architecture
• Define REST API standards, service contracts, versioning, error handling, and backward compatibility.
• Design synchronous and asynchronous integration patterns, including event-driven architecture where appropriate.
• Establish API security, throttling, resiliency, observability, and fault-tolerance standards.
• Define integration patterns between frontend applications, backend services, identity platforms, and external systems.
• Identify opportunities to reduce point-to-point integrations and improve platform reusability.
5. Cloud-Native Architecture & DevOps
• Design cloud-ready and cloud-native application architectures on AWS and/or Azure.
• Define containerization, deployment, scaling, and orchestration strategies using Docker and Kubernetes.
• Collaborate with DevOps teams on CI/CD pipelines, release management, infrastructure automation, and environment strategy.
• Establish observability standards covering logging, metrics, tracing, alerting, and production diagnostics.
• Evaluate cloud service capabilities, resilience patterns, disaster recovery, availability, and operational cost optimization.
6. Data, Performance & Reliability
• Define data architecture and persistence strategies using relational and NoSQL databases.
• Establish data ownership, transaction boundaries, caching, consistency, and data access patterns.
• Define non-functional requirements and performance benchmarks for critical customer journeys.
• Guide performance engineering, capacity planning, load testing, and bottleneck analysis.
• Design for fault tolerance, graceful degradation, high availability, and disaster recovery.
7. Architecture Governance & Technical Leadership
• Lead architecture reviews, technical design reviews, and solution walkthroughs.
• Validate implementation against approved architecture, security standards, and engineering guidelines.
• Guide technical leads and development teams throughout design, development, testing, and production deployment.
• Identify technical risks, dependencies, architectural gaps, and modernization opportunities.
• Mentor engineers and promote reusable components, consistent implementation patterns, and continuous improvement.
• Communicate architecture decisions and trade-offs to technical and non-technical stakeholders.
• Support estimation, solution feasibility assessments, technical proposals, and delivery planning.
