Identity & Access Management
Identity platform architecture across all categories: customer identity (CIAM) for digital services, workforce identity (WIAM) for enterprise SSO, and machine/workload identity for service-to-service and AI agent authentication. OAuth 2.0, OpenID Connect, SAML 2.0, SCIM. Deep experience with Auth0, Okta, Microsoft Entra ID, Keycloak, and custom-built identity systems. SSO federation, MFA, directory integration (LDAP, Active Directory), user lifecycle management, and non-human identity management. Platform evaluation, migration planning, multi-tenant identity architecture, and compliance alignment.
API Security & Policy Engineering
Fine-grained authorization design: RBAC, ABAC, ReBAC, and policy-as-code with OPA (Open Policy Agent) and Cedar. OAuth 2.0 token design, scope strategy, and API gateway authorization. Zero-trust architecture for multi-tenant platforms. WAF configuration, DDoS protection, bot detection, rate limiting, and request/response transformation. API security strategy for environments where callers include humans, code, and autonomous AI agents. Compliance-driven access control for regulated industries.
Cloud Infrastructure & Edge
Cloud architecture and traffic management across AWS, GCP, and Azure. Traffic ingress, edge distribution, CDN, load balancing, and path-based routing. Kubernetes cluster design and operations (EKS, GKE, AKS), service mesh (Istio, Linkerd), GitOps (ArgoCD, Flux), Helm chart development, and multi-cluster federation. Infrastructure-as-code with Terraform and Pulumi. Multi-region and multi-cloud deployment strategies, failover design, and circuit breaking. Cloud migration, cost optimization, and FinOps consulting.
Product Engineering & Architecture
End-to-end product engineering from concept through production operations. System architecture for cloud-native products, especially at the infrastructure layer: traffic management, identity, and security platforms. High-throughput API design, distributed systems, event-driven architectures, control plane / data plane separation, and encryption at every layer. Developer experience engineering: CLI tools, SDKs, management consoles, and API documentation. Product thinking applied to infrastructure problems.
Cloud Platforms & DevOps
CI/CD pipeline design with GitHub Actions, GitLab CI, and Jenkins. Observability: Prometheus, Grafana, Datadog, OpenTelemetry, and Sentry. SRE practices: SLO/SLI frameworks, incident management, capacity planning, and on-call design. Container runtime operations, certificate management, secrets management, and infrastructure security hardening.
Full-Stack Development
Backend: Go, Rust, Python, Node.js, Java, C#. REST, GraphQL, and gRPC API design. Frontend: React, Next.js, Vue, TypeScript. Mobile: Swift, Kotlin, React Native, Flutter. Database design across PostgreSQL, MySQL, MongoDB, Redis, and Elasticsearch. End-to-end development from system architecture to deployment, with a focus on performance, security, and maintainability.
