(00) negative_space — board advisory & expert product leadership

for companies where the product is the hard part_

operations, hardware, AI systems, and the teams that ship them.

i defined the modern in-person ecommerce returns experience to scale. i led one of the first industry-scale human-in-the-loop AI operations — computer vision, sensor fusion, and deep learning powering 300+ checkout-free stores. i built the orchestration layer that decides what 200M+ prime video viewers see. now i lead product and design for the world's leading counter-drone technology company.

what i see

the thesis

as LLMs commoditize code, the bottlenecks that matter shift: hardware, sensing, integration, deployment, reliability.

the companies that win will be the ones that ship atoms and bits together — fusing ML models with physical systems, operating them at scale, and making hard technology disappear for the end user. that's the work i've done for a decade and the work i'm doing now.

about

the arc, the teams, the work

from checkout-free retail to content orchestration for 200M+ viewers to counter-drone defense — i build products where AI meets the physical world, and i build the teams that ship them.

01

origins

before amazon, i led operations across retail and healthcare. at amazon, i started running operations for a large-scale robotics facility, then moved to build amazon's first in-person retail presence — going from regional operations leader to senior product manager. i built the in-person returns experience from early whiteboard sketches to the box-free, label-free returns program millions use today. that was where i discovered what i wanted to do.

02

just walk out

that led to Just Walk Out technology, where i spent four years as the de facto technical product leader for how the system was built — from cameras to computer vision models to the human-in-the-loop operations that made the AI actually work. i scaled that operations team from 20 to 1,000+ and grew from manager to GM leading product, engineering, UX, data science, and data engineering.

03

the arc to present

after that, i built the orchestration layer at prime video that balanced personalized content, editorial placements, business-priority overrides, and display advertising for 200M+ monthly viewers. at ring, i led a small senior team defining a new category of RF-based hardware and AI-driven software experiences. now i lead product and design at dedrone by axon — counter-drone systems integrating RF sensors, radar, cameras, and electronic warfare, deployed across 1,000+ sites in 33 countries, protecting 53 airports and critical infrastructure for 6 of the 7 G-7 governments.

04

team scale

i've managed 30+ person product and design organizations and 100+ person technical teams across software engineering, data science, and TPM. i've built operations teams from scratch and scaled them past 1,000. i've also deliberately dropped down to a 3-person team to build a new concept from zero. team size is a by-product of building the right team for the result needed.

AI systems & human-in-the-loop

operations before models

AI systems are operations problems before they are model problems.

01

the hitl platform

at Just Walk Out technology, i built and led the human-in-the-loop operations platform that made checkout-free retail actually work. this wasn't labeling data for a training pipeline — it was a full production system: computer vision inference review, labeling workflows, quality feedback loops, and exception handling for an AI that processed every shopping session across 300+ stores. i scaled the operations team from 20 to over 1,000, built the tooling and processes that supported them, and was the product leader deciding how the customer experience would land in an AI system that was genuinely ahead of its time.

02

from internal ops to aws products

the tools and processes we built for that HITL operation didn't stay internal. they informed products AWS later built for external customers — including ideas that informed SageMaker Ground Truth — while they were still evolving from PRFAQ into product. building at that scale, with that complexity, created organizational knowledge that became commercially valuable beyond the original use case.

03

prime video orchestration

at prime video, the AI systems problem looked different but shared the same DNA. the challenge wasn't recommendation in a vacuum — it was building the orchestration layer that arbitrated between personalized content, editorially curated placements, business-priority overrides, and display advertising, all competing for the same screen real estate for 200M+ monthly viewers. multiple stakeholders, multiple objectives, one viewer experience. i led 16 product managers and designers with 125+ ML engineers building the systems that made those tradeoffs in real time.

04

the thread to dedrone

at dedrone, the pattern continues — and the scope grows. i lead the entire product line for the division: multiple RF detection sensors and a handheld RF jammer, built and shipped, with next-generation products in progress. RF machine learning drives detection; the system fuses RF, radar, camera, and acoustic signals into one operating picture; product and partner integration runs across Axon Air with Skydio and DroneSense. the hardware deploys where customers need it. same class of problem: AI that must work in the physical world, with real consequences for failure.

software + hardware

product leadership

software is getting cheaper. the hard part is everything around it.

01

the physical portfolio

i've built products across the full physical-digital spectrum — and shipped all but one: locker hardware and in-store return kiosks (Amazon Locker+), ceiling-mounted camera arrays and sensor gateways (Just Walk Out), multiple RF detection sensors and a handheld RF jammer, with next-generation products in progress (Dedrone). the one that didn't ship: a new category of RF-based home security hardware at Ring, taken through DVT units and a beta app. in every case, the product challenge wasn't the software alone — it was the integration of software with physical systems, deployment at scale, and reliability in uncontrolled environments.

02

the thesis, applied

this is what i mean when i say the bottlenecks are shifting. the model is increasingly a commodity. the hard problems are: how do you deploy sensors reliably across 1,000+ sites in 33 countries? how do you build HITL operations that maintain AI quality at scale? how do you fuse data from four different sensor modalities into a real-time operating picture? how do you make an orchestration layer that serves 200M+ viewers while satisfying competing business objectives? these are operations, integration, and systems problems — not model problems.

03

what's next

whether it's a board seat, an advisory role, or an operating role — the value i bring is depth at the intersection of physical systems, AI, and operations at scale. i've done the work of shipping hard technology, not just building software that sits on top of someone else's infrastructure.
