capabilities

Where I add the most leverage.

01

Product Engineering

Taking products from ambiguous requirements through architecture, implementation, QA, deployment, and iteration.

02

Frontend Architecture

Building scalable TypeScript applications, complex workflows, reusable component systems, responsive interfaces, and maintainable frontend foundations.

03

AI-Native Delivery

Designing reusable agent harnesses with profiles, policies, fail-closed contracts, guardrails, run-plan schemas, observability, validation, and human review gates.

04

Technical Enablement

Helping engineers, clients, and nontechnical teams understand systems, make better decisions, and become more independently capable.

consulting
applied harness engineering

AI-native modernization needs more than an agent.

I help teams install domain-specific harnesses: repeatable workflows, policies, contracts, readiness gates, templates, and evidence requirements for real product and engineering work.

Good agent work needs operating boundaries.

  • Start with the real user problem.
  • Understand the system before changing it.
  • Turn ambiguity into a written plan.
  • Give agents clear contracts and boundaries.
  • Keep humans in the approval loop.
  • Verify the output before trusting the speed.
  • Feed failures back into the system.
