Building an Evidence-Grounded Personalization Engine

The Business Problem

High-value business workflows often require the same difficult combination: interpreting an unstructured request, identifying the most relevant proof points, creating a tailored response, and maintaining accuracy at volume.

Generic AI tools can create fluent output, but they can also distort facts, dilute professional voice, or introduce unsupported claims. The product challenge was not simply generating documents faster. It was building a reliable system that could personalize output while remaining grounded in verified source data.

The Solution

I designed and built a grounded AI personalization engine: a multi-agent workflow orchestrated in n8n. The system uses a structured accomplishment and evidence database as its source of truth, then evaluates incoming opportunities against that data before producing tailored, review-ready materials.

The system was first proven in a career-application use case, where accuracy, relevance, and scale matter. The underlying architecture is designed as a reusable pattern for any workflow that requires evidence-based personalization.

The Multi-Agent Architecture: Eight Specialized Components
Agent 01
Sourcing Agent
Collects new opportunities or incoming requests from defined sources and external APIs.
Agent 02
Vetting Agent
Evaluates incoming opportunities against defined relevance, quality, and priority criteria.
Agent 03
Requirements Parser & Evidence Matcher
Parses the request, extracts relevant requirements and keywords, then matches them against the verified evidence database.
Agent 04
Fit Scoring Service
Applies structured scoring criteria to prioritize the highest-value opportunities rather than relying solely on subjective LLM judgment.
Agent 05
Tailored Content Generation Agent
Produces role-, client-, or opportunity-specific materials using only relevant, matched, verified source content.
Agent 06
Reviewer Agent
Reviews generated materials for accuracy, alignment, completeness, voice, and potential issues.
Agent 07
Central Orchestrator Agent
Coordinates data movement, workflow state, and handoffs across the system.
Agent 08
Document Preparation & Deployment Agent
Prepares final materials for human review, approval, and deployment.

The Source of Truth
Instead of asking an LLM to invent a persuasive response, the system asks: Which verified evidence best demonstrates alignment with this opportunity? The model works from structured source data rather than inventing or rewriting professional history.
Human-in-the-Loop

The system is designed to accelerate research, extraction, matching, drafting, and quality checks—not to replace judgment. A human reviewer retains final authority over the opportunity, the output, and the decision to deploy it.

AI handles repeatable analysis and preparation. Humans retain judgment and accountability.
Early Validation

Verified by an independent user in a career-application use case, the system supported approximately 70 highly tailored applications per day and contributed to securing a role within three days. This is directional early validation—not a guaranteed outcome—but it demonstrated that structured source data, fit scoring, and human-reviewed AI personalization can increase speed without sacrificing relevance.

Case Study 020→1 Product DevelopmentMortgage SaaS

Building a 0→1 Multi-Tenant Mortgage SaaS Platform

0→1 Product Development · Mortgage SaaS · Multi-Tenant Architecture · AI-Assisted Development · Full-Stack Product Ownership

The Challenge

A mortgage-industry contact approached me to build an online borrower application that mortgage brokers could place on their websites. Rather than immediately building the requested application, I asked why they needed it.

I discovered that many mortgage brokers use application links provided by wholesale lenders directly on their websites. If a borrower's scenario doesn't fit that lender's programs, the loan is denied—even though another lender may have a program that fits. The broker loses the loan, the borrower is left unhappy, and revenue is lost on a loan that may have been approved elsewhere.

The Product Opportunity

I reframed the opportunity around giving brokers control of their own loan application process—allowing them to shop the mortgage package with the wholesale lender that is the best fit, leading to more approvals, more closed loans, higher revenue, and happier borrowers.

Start with the business problem → uncover the real opportunity → define the product → translate it into technical requirements → build → validate → iterate.

Building With AI

AI-assisted development changed how I approached implementation. One of the biggest lessons was that documentation is critical when building with AI. If a bug is fixed but the documentation isn't updated, the next AI-assisted implementation can work from outdated assumptions and introduce new problems.

Requirement → Build → Debug → Update Documentation → Next Requirement

When AI is part of the development team, documentation is part of the product.

Case Study 03Fractional CPOProduct Strategy

Turning Founder Vision into an Executable Product Roadmap

Fractional CPO · Product Strategy · Customer Discovery · MVP Definition · Roadmap Prioritization · Delivery · Go-to-Market Alignment

The Challenge

A founder had an early-stage product and needed senior product leadership to bring structure to the vision, clarify what should be built, and determine how the business could move from concept toward a scalable product.

  • Who is the product actually for?
  • What core problem are we solving?
  • What belongs in the MVP vs. post-launch phases?
  • How do we quantify and prove product value?
  • What milestones must the business hit before scaling?
What I Did
  • Redefined Product Focus: Clarified the ICP and brought strategic discipline to the roadmap.
  • Structured the MVP: Defined the precise scope needed for early validation, separating core launch mechanics from secondary capabilities.
  • Defined the USP: Refined messaging to articulate clear customer outcomes rather than abstract technical capabilities.
  • Quantified Customer Value: Built a framework to calculate measurable ROI for end users, directly strengthening the commercial sales pitch.
  • Established Product Discipline: Introduced rigorous requirements, validation protocols, documentation standards, and development workflows.
  • Connected Product to Business Strategy: Aligned product delivery with unit economics, pricing models, go-to-market channels, and investment readiness milestones.
The Fractional CPO Difference
What should we build—and for whom?
Why will the market care, and what value is created?
What metrics do we need to prove before allocating capital to scale?

That is the value I bring as a Fractional CPO: aligning product vision, technical architecture, and business strategy into a single operational roadmap.

The Challenge

E*TRADE's Income Estimator allowed customers to view income information associated with their portfolios, particularly around earnings activity. The product depended on a shared data feed. A problem with the underlying data was producing inaccurate information for some ticker symbols.

Technology had a daily remediation process intended to correct the data. But it wasn't fixing the underlying problem. The cycle became: Incorrect data → manual remediation → temporary fix → new daily feed → problem returns.

The immediate issue was data accuracy. The real problem was the technical debt created by repeatedly treating the symptom instead of the source.

The Complexity Nobody Could Ignore

The problematic data feed was shared across four other product teams—and their products were working. I couldn't simply say "this feed is causing problems, let's replace it." The other teams had no reason to voluntarily take on migration risk.

The technical solution would only work if I could get the organization to move with it.

Finding the Root Cause

I traced the recurring data problems back to changes in the underlying data environment following the Thomson Reuters merger. Instead of continuing to patch the existing feed, I worked with the account executive to identify an alternative data file that could provide the required information accurately.

There was another obvious alternative: Bloomberg. But Bloomberg would have required approximately $1 million in licensing costs. I needed a solution that fixed the problem without creating a significantly larger cost problem.

Validate Before You Migrate

I worked with Technology to build a proof of concept using the alternative feed. Because four other teams depended on the existing feed, I needed to validate that the alternative also supported their required data points. I went to each team individually.

I didn't start with one giant meeting asking four teams to approve a change. I built alignment individually. Once the teams understood the problem, the proposed solution, and the impact on their products, I brought the stakeholders together for the broader migration decision.

The Product Leadership Lesson
A technical problem isn't always a technical problem. The hardest part wasn't finding another data feed. It was recognizing the shared dependency, understanding who would be affected, proving the alternative could support their needs, and getting four teams to move from a solution that worked for them to one that was better for the broader platform.

The Challenge

At E*TRADE, I owned product strategy for Quotes & Research at a time when online brokerage research experiences were relatively static and conservative. Customers wanted more interactive tools to research faster, understand investment opportunities, and make informed buy/sell decisions.

FINRA requirements made teams cautious about introducing new research and analytical experiences. The opportunity was clear: give customers a more interactive way to explore equity fundamentals without compromising regulatory requirements.

The Product Opportunity

I discovered Trefis, an interactive equity modeling platform that allowed users to explore company fundamentals through a visual, drag-and-drop experience. The challenge was turning that opportunity into a product that could actually operate within E*TRADE's regulated environment.

Why This Matters
This wasn't simply a vendor integration. I identified a customer problem, found a product opportunity, built the internal case for it, navigated regulatory constraints, coordinated multiple internal and external teams, and took the product through approval, implementation, and launch. Customer insight → Product opportunity → Regulatory strategy → Cross-functional execution → Launch → Measurable outcome.
