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.
Notes from the work
Occasional essays and build logs that document real decisions—not a content treadmill. Original project notes can be adapted for LinkedIn, Upwork and video without losing their technical substance.
Designing an AI buyer concierge that knows the difference between property evidence and plausible language.
Publishing path establishedHow local intelligence could turn physical home activity into permissioned, evidence-backed property events.
Publishing path establishedThe unglamorous architecture—state, observability, exceptions and human control—that makes an AI system dependable.
Publishing path establishedThe builder behind the work
I’m Jeffrey Walker, an AI Systems Engineer who helps founders and teams turn ambitious ideas into dependable operational systems.
My background spans technology strategy, software delivery, business communication and entrepreneurship—including enterprise work supporting Microsoft and AWS. That range helps me see both sides of an AI project: what the system must do technically and why it needs to exist commercially.
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.
