• Search and indexing solutions
• Object storage for source content and embeddings
• Caching for performance and scalability

Cloud-Native Delivery

Deploy and operate services primarily on AWS, following best practices for:

• IAM and security
• Scalability, resiliency, and availability
• CI/CD and environment management

Integration & UX Enablement

Integrate with enterprise tools and services via secure APIs and gateways. Support React-based front-end patterns and collaboration integrations to enable effective user experiences.

Observability & Operations

Implement logging, metrics, and tracing across agent workflows, model calls, and integrations. Support incident diagnosis, performance tuning, and ongoing optimization.

Working with the Business

Engage directly with business stakeholders to:

• Translate use cases into technical designs and acceptance criteria
• Communicate trade-offs across quality, cost, risk, and delivery timelines
