Expert-Vetted on Upwork · Auburn, WA
I design and deploy production AI systems that connect trusted data to real business workflows—from property intelligence and buyer experiences to identity, documents, payments and human decisions.
Selected systems
Founder products, client delivery and clearly labeled future-state research.
An AI-assisted FSBO platform that helps homeowners turn verified property knowledge into a polished selling experience.
Tekia combines Property Memory, an evidence-grounded buyer concierge, lead capture, showing requests and campaign support—beginning with a flagship property grounded in 42 verified facts.
A high-trust tenant verification system carrying each case through one auditable operational lifecycle.
Payments, documents, identity verification, signatures and WhatsApp communication were integrated around explicit state—not a collection of disconnected screens.
An independent experimental studio exploring the property intelligence layer for the homes of tomorrow.
The research asks how edge AI could help a home observe, understand, verify and remember—while raw household life remains local and people remain in control.
Where I create leverage
AI systems that coordinate tools, data, business rules and human review across consequential operational processes.
Property memory, retrieval and provenance patterns that make fluent answers traceable to trusted facts.
From architecture and product decisions through APIs, databases, interfaces, integrations and deployment.
Future-state exploration of edge inference, smart-home interoperability and local property intelligence.
Published writing
Freelance and contract writing produced for enterprise clients—whitepapers, blogs and ebooks that turn technical AI work into language non-technical stakeholders trust. These are writing samples from my work at each company, not my own IP.
A whitepaper for Codoxo on how generative AI detects coding errors, duplicate payments and fraud in healthcare claims—cutting into the 15 days it takes a clinician to review a single in-patient claim.
Read at CodoxoA co-branded whitepaper for Nutanix and Red Hat, distributed via Arrow's public-sector portal, on adopting generative AI within real government IT budgets and legacy-infrastructure constraints.

Read at AWSThe builder behind the work
I’m Jeffrey Walker, an AI Engineer & Writer who helps founders and teams turn ambitious ideas into dependable systems—and helps enterprise teams explain complex AI work in language people actually read.
My background spans technology strategy, software delivery, business communication and entrepreneurship—including engineering and writing work for enterprise clients like Codoxo, Nutanix, Red Hat and AWS. That range helps me see every side of an AI project: what the system must do technically, why it needs to exist commercially, and how to explain it clearly to the people who have to trust it.
Today my commercial focus is Tekia’s FSBO platform. PhysicAI Labs remains a separate future-state research studio for edge AI and the physical home. The distinction matters: shipped work is presented as shipped work, and research is presented honestly as research.
