Services

Engineering services

Scoped engagements with clear ownership, covering architecture through runbooks. Each engagement names what is delivered and who owns it in production.

System design

Architecture for data flows, services, and integrations. We document constraints, failure modes, and deployment boundaries before writing production code.

What it covers

  • Data flow and service boundaries
  • Integration contracts between systems
  • Failure modes and degradation paths
  • Deployment topology and environments

What you receive

  • An architecture document
  • Interface and contract definitions
  • Documented constraints and assumptions
  • A sequencing plan for the build

Build & integrate

Application development, API design, model wiring, and integration with existing stacks. Delivery includes tests, environments, and handover materials.

What it covers

  • Application and API development
  • Model and service wiring
  • Integration with systems already in place
  • Test coverage and environment setup

What you receive

  • Working software in your environment
  • A test suite you can run
  • Environment and deployment configuration
  • Handover documentation

Operate & observe

Logging, metrics, alerting, release process, and operational ownership for systems we run — including platforms such as CaQeh.

What it covers

  • Structured logging and metrics
  • Alerting with named ownership
  • Release and rollback process
  • Incident detection and response paths

What you receive

  • Dashboards for the running system
  • Alert rules with routing
  • Runbooks for known conditions
  • Defined escalation paths

Secure by default

Access control, secrets handling, abuse resistance, audit trails, and review of AI/LLM attack surfaces where models sit in the request path.

What it covers

  • Access control and secret management
  • Input validation and abuse resistance
  • Audit trails for privileged actions
  • Review of model-facing attack surfaces

What you receive

  • Threat notes for the system in scope
  • Implemented controls in the codebase
  • Audit logging where it matters
  • Written review findings

What we mean by a production system

Four layers on the request path, with access control and observability running down both sides rather than bolted on at the end. This is the shape most of our engagements produce.

Request path Edge TLS, routing, rate limiting Application APIs, business rules, model calls Services queues, workers, integrations Data stores, schemas, migrations Access least privilege secrets management environment isolation rotation paths Observability structured logs metrics on key paths alerts with an owner audit trail on writes
A production system, in layers

How engagements run

Every engagement follows the same four stages — discovery, architecture, build, and operate — with a written output at each stage. See our approach → or read the FAQ →
