How I ship

Isolation first. Evals before merge. The pipeline is part of the product — not a wrap-up after the demo.

How do you prevent tenant leaks?

Isolation in Prisma, SQL Server RLS, and CI that fails unscoped queries. Walkthrough: multi-tenant marketplace.

How do golden evals gate tool-calling agents?

A 2,000+ line suite is a merge gate, not a dashboard after deploy. See Eva and operating principles.

Is the release path part of the product?

Trivy, SBOM, signed images, and blue-green deploys. For hiring context see the FAQ and engagements.

01

Constraint

Until the constraint is named

Name isolation, eval, latency, and delivery constraints before picking a stack. The first sentence of every case study is a production problem, not a tool list.

Deliverables:

  • Constraint brief
  • Tenancy / threat notes
  • Measurable success criteria
  • What we will not ship
02

Architecture

Until the design is reviewable

Two-layer tenancy, RBAC around tools, eval gates, and zero-trust delivery — designed as the product, not a wrap-up after the demo.

Deliverables:

  • Isolation model
  • Tool / RBAC map
  • Eval plan
  • Pipeline sketch
03

Evals in CI

The build

Build with golden evals, coverage, and CI that refuses unscoped tenant queries. Agents without evals stay prototypes.

Deliverables:

  • Working system
  • Golden evals in CI
  • Coverage gates
  • Staging with the same checks
04

Ship

Until production is boring

Trivy, SBOM, signed images, blue-green, rollback. The pipeline is part of the product — production should be boring.

Deliverables:

  • Production deploy
  • Signed, scanned artifacts
  • Rollback path
  • Knowledge transfer

Operating principles

The same constraints I use in production — not a client-project warranty.

Isolation First

Multi-tenant data isolation enforced at Prisma and RLS levels before any application code executes.

Evals Before Merge

Deterministic eval suites run in CI to prevent agent drift, regression, and prompt hallucinations.

Pipeline Is The Product

Observability, trace correlation, and automated rollback strategies deployed alongside the model runtime.

Transparent Control

Explicit schemas, typed tool boundaries, and fail-safe human overrides over black-box autonomy.

How we collaborate

The same channels used on production teams — not a freelance toolkit pitch.

GitHubPRs, reviews, and the source of truth
CIEvals, tenancy guards, and merge gates
LinearWork that maps to a constraint
SlackAsync by default
NotionArchitecture notes, not a pitch deck
CalendarHiring and scoped working sessions

Let's talk about the system you need to ship

Hiring managers and founders: I own architecture through production — agents, tenancy, and the pipeline.
