Origin Story

Before ChatGPT, there was the hard way.

Most people working in "AI products" today learned the field through APIs and prompt playgrounds. I learned it by breaking models in production.

In 2015, I was writing NLP rules by hand to extract entities from unstructured job postings — no transformers, no embeddings, just regex, domain logic, and painful edge cases. I watched statistical models drift. I debugged Elasticsearch ranking failures that looked like "AI problems" but were really data pipeline problems.

By 2019, I was leading teams building computer vision systems for PCB defect detection and digital twins for factory floor management — long before anyone called it "agentic AI." Designing human-in-the-loop workflows, handling model uncertainty in production, deciding when the system is wrong — all of that predates ChatGPT by years.

That depth — knowing where AI systems fail, how to instrument them, how to build trust with users who've been burned before — is what I bring to every agentic AI product today.

"The challenge wasn't building the AI — it was getting 10,000 salespeople to trust it."

ZoomInfo had the data. It had the model. What it didn't have was adoption. Account Fit Score was at 30% when I joined — not because the model was wrong, but because the product experience was broken. Sales teams ignored it, routed around it, or used it wrong. I spent the first quarter talking to the people who weren't using it. The blockers were implementation complexity, opaque scoring logic, and a mismatch between model optimization and what reps needed to close deals.

I redesigned the explainability layer so reps could see why an account scored the way it did. I simplified onboarding. I built CRM feedback loops connecting win rates back into model refinement cycles. Twelve months later: 60% adoption. The product hadn't changed. The trust had.

From there I moved into agentic territory — LLM + RAG systems that autonomously segment accounts, generate outreach recommendations, and hand off to reps with full context. The key design challenge in agentic products isn't the automation. It's the handoff. I built explicit human-in-the-loop override workflows into every agent surface.

"Healthcare AI doesn't get a second chance. One wrong extraction can cascade into a billing error, a misdiagnosis, a compliance violation."

Moving into healthcare, I faced a domain where AI failure has the highest human cost. My mandate: build a document intelligence product that extracted structured data from unstructured clinical notes with HIPAA compliance built in from day one.

The hardest product decision wasn't the NLP architecture. It was defining what the system should refuse to do. I designed confidence thresholds below which Dexter escalated to human review rather than committing an extraction. I built audit trails into the core data model. We won 6 RFPs because our proposals showed we understood where the AI would fail — and had systematic plans for it.

"Factory floors don't care about your model's accuracy on a test set. They care whether the line stops."

This is where I learned what production AI really means. We built digital twin systems for PCB manufacturing — real-time computer vision pipelines that detected defects before they compounded and predicted equipment failures before they halted production. Leading a 25+ member team, I operated at every altitude simultaneously.

Clients saved over $1M annually — not because our model had the highest benchmark scores, but because we designed workflows around the model's uncertainty. Every critical decision had a human escalation path. That philosophy now applies to LLM outputs rather than CV model outputs — but the principle hasn't changed.

"The fastest way to understand why a product fails is to have been the engineer who built it."

Before moving into product, I was the bridge between data science and engineering. I built annotation tooling, designed ML deployment pipelines, and watched models fail in ways no benchmark had predicted. This is where I learned what happens when a PRD is underspecified — and it permanently changed how I write them.

I was promoted directly from this role to Product Manager — an unusual path that gave me engineering credibility most PMs don't have when walking into ML design reviews.

  • Refactored core ML codebase — improved efficiency 50%, unified coding and deployment standards
  • Boosted model performance by 90% and cut annotation time from 5 minutes to 30 seconds through purpose-built tooling
  • Designed and deployed ML models in production including monitoring, drift detection, and rollback procedures
  • Promoted directly to Product Manager — rare engineering-to-PM track within BUDDI.AI

"When a SIP call drops, the customer doesn't know why. Finding out used to take 24 hours. We made it 30 seconds."

BroadSoft powered UCaaS infrastructure for enterprise customers. Diagnosing failures meant parsing thousands of SIP signaling logs by hand. I built a diagnostic intelligence toolkit that indexed SIP log streams into Elasticsearch in real time, detected anomaly patterns, and surfaced root causes automatically. This was my first lesson in what data products do for operations teams — transforming reactive firefighting into proactive intelligence.

  • Built SIP diagnostic toolkit — reduced issue resolution from 24h to 30 seconds
  • Designed and scaled Elasticsearch cluster for high-availability voice session indexing
  • Received Peer Choice Award (2017) — recognized for technical impact and collaboration

"My first AI job. No LLMs. No embeddings. Just rules, messy data, and the slow satisfaction of watching accuracy climb."

Burning Glass parsed millions of resumes and job postings to extract labour market insights. I wrote NLP extraction rules, managed Elasticsearch clusters, and improved a statistical model's accuracy from 95% to 98% through methodical rule engineering. This taught me that AI product work is 80% data quality and 20% model architecture — a belief I've carried ever since.

  • Improved statistical model accuracy 95% → 98% on labour market unstructured data
  • Built entity extraction rules for Labour Market Core Application — resumes and job postings at scale
  • Managed Elasticsearch cluster operations — replaced older Spark-based system

What I Bring

Value you won't find on most PM résumés.

Ten years of building the hard way produces capabilities that can't be learned in a sprint workshop or a prompt engineering course.

I spec AI failure modes before engineering starts
Most PRDs describe what the AI should do. Mine also explicitly document what happens when it's wrong — confidence thresholds, escalation paths, human override flows. Engineers and QA know what "done" actually means before a line of code is written.
Real proof: Designed Dexter's escalation architecture for HIPAA compliance. Zero extraction errors in production in the first 6 months.
I turn adoption problems into trust problems — then solve them
AI adoption failure is rarely a model problem. It's a trust problem: users don't understand the output, can't explain it to their manager, or have been burned before. I design explainability layers and feedback loops that convert skeptics into power users.
Real proof: Account Fit Score adoption doubled from 30% to 60% without changing the underlying model — only the product experience around it.
I know which AI bets are worth making — and which aren't
Having built AI systems before LLMs, I can evaluate whether a problem actually needs a model or just better data architecture. I've killed AI features that would have wasted 3 months of engineering time and replaced them with simpler solutions that shipped in 2 weeks.
Real proof: Redirected a planned DL model for intent detection to a rule + Elasticsearch hybrid — better accuracy, 4× faster to ship, infinitely easier to debug.
I speak fluently across engineering, data science, and C-suite
I've been the engineer, the data scientist, and the PM. I can debug a training pipeline in the morning and present a business case to a CEO in the afternoon. No translation tax between teams. No "I'll check with engineering" delays.
Real proof: Led 25+ person cross-functional teams (engineers, QA, data scientists, designers) across 3 time zones with zero process overhead.
I design for compliance from the first line of the PRD
HIPAA, data residency, audit trails, model explainability for regulated industries — these aren't afterthoughts I add before launch. They're architectural decisions I make at discovery. This saves months of rework and makes enterprise sales dramatically faster.
Real proof: Won 6 RFPs in US healthcare and Middle East markets — buyers cited compliance architecture as a key differentiator over competitors.
I build feedback loops that make the product smarter over time
I design CRM integrations, usage telemetry, and model monitoring pipelines as product features — not engineering afterthoughts. The result is a product that improves with every user interaction rather than degrading silently after launch.
Real proof: Built structured feedback loops connecting AFS pipeline creation and win rates back into model refinement — accelerating iteration velocity across teams.

The rarer things.
