- Drive quality with unit/integration/contract testing, test data strategy, and automated quality gates.
- Cloud & Platform
- Design for AWS/Azure/GCP, container orchestration (Kubernetes), service mesh, and CI/CD.
- Implement infrastructure-as-code (IaC) patterns and secrets management.
- Partner with SRE/Platform teams on monitoring, alerting, logging, tracing, and cost governance.
- Data & Integration
- Architect integrations across SQL/NoSQL, caching (Redis), and event streams (Kafka/Pulsar).
- Define data contracts, schema evolution strategies, and idempotent/eventual consistency patterns.
- Security & Compliance
- Embed AppSec best practices, OWASP controls, secure API/auth (OAuth2/OIDC), and zero trust patterns.
- Ensure compliance with regulatory and audit requirements where applicable.
- Stakeholder Partnership
- Translate business needs into technical roadmaps and architecture runway.
- Communicate trade-offs and decisions to both technical and non-technical audiences.
