AI Engineering

Custom AI, engineered into production.

AI Engineering builds the systems a roadmap specifies: customer-facing AI products and internal AI systems, built to a written specification and deployed in the client's environment.

Customer-facing

Product engineering

Customer-facing AI products designed, built, and shipped with the client's team.

ML engineers, software engineers, product managers, and designers take a product from specification to release. Models are selected against an evaluation set built from the client's data, and each product ships with the interfaces, APIs, and analytics required to operate it.

Scope

  • Conversational assistants for customers and staff
  • Document and identity capture
  • Search and recommendation
  • Booking, onboarding, and service flows
Internal

Enterprise AI systems

AI embedded in internal operations and connected to the systems already in place.

Nexa builds agents, retrieval, and automation that operate inside the client's existing infrastructure. Requests captured by customer-facing products open work in these systems, and status returns to the customer through the same product. Each system inherits the client's identity and access controls, writes to the systems of record, and keeps a human approval step on actions with financial or regulatory consequence.

Scope

  • Agents for multi-step operational workflows
  • Retrieval over internal documents and records
  • Workflow automation and reporting
  • Integration with ERP, CRM, and core platforms

Reference architecture for an AI Engineering build. Customer requests open work in internal systems, and status returns to the customer through the same product.
Production

Deployment and enablement

Production deployment in the client's environment and a team equipped to operate it.

Systems deploy to the client's private cloud or on-premises infrastructure. Each deployment includes an evaluation suite that runs against every release, monitoring for quality and cost, and documentation and training for the team that operates the system after handover.

Deliverables

  • Deployment to private cloud or on-premises infrastructure
  • Release evaluation suite
  • Quality and cost monitoring
  • Documentation, training, and handover
Acceptance

How a build is accepted

Release depends on criteria agreed before engineering starts.

Each build is tested against the acceptance criteria in the specification and the evaluation set built from the client's data. The client's team runs acceptance testing, and the system moves to production after written sign-off.

Checkpoints

  • Acceptance criteria fixed in the specification
  • Evaluation results reported per release
  • Acceptance testing by the client's team
  • Written sign-off before production
Engineering practice

How Nexa builds

Four practices apply to every build.
