Data Platform Architecture · Integration & Quality

How I build data platforms that earn trust at scale.

I've spent the last decade designing data ingestion, integration, and quality monitoring systems for enterprise platforms where dozens of external partners send messy, inconsistent data and the AI and analytics downstream depend on it being right. This is how I think about the problem.

40+Vendor integrations
6+Source system types
5xEngineering velocity gain
~95%Client retention

Four layers from raw data to reliable intelligence

Every platform I've built follows the same structural pattern: normalize messy external data into a consistent core, validate and gate it on arrival, monitor it continuously for degradation, and only then let analytics and AI consume it. The domain changes but the architecture doesn't.

1. External Sources
  • 40+ vendor partner systems
  • EHRs, payer systems, hospital ADT feeds
  • Claims, assessments, satisfaction surveys
  • Multiple schemas per vendor
  • Custom fields per client/provider
  • Varying formats, frequencies, quality
2. Ingestion & Normalization
  • Unified API with parameterized endpoints
  • Core schema mapping (~80% standard)
  • Custom field mapping per vendor (~20%)
  • Value standardization via lookup tables
  • Developer-first documentation
  • Write-back to source systems
3. Quality Gates & Monitoring
  • Gate 1: Accept/reject at ingest, errors back to sender
  • Gate 2: 24-hr trend analysis across all feeds
  • Threshold-based alerts by severity
  • Drill-down by vendor, client, patient
  • Data lineage tracing (UI-level)
  • Outlier and degradation detection
4. Analytics & AI
  • Scorecard and operational analytics
  • Predictive models (millions of records)
  • Cross-system entity linking
  • Multi-dimensional reporting
  • AI-powered monitoring prototypes
  • Decision-support systems
Ingest
Validate
Consume

Two gates, zero assumptions

I designed a two-checkpoint quality system that catches problems at the moment of ingestion and monitors for slow degradation over time. The first gate decides whether to even save the data. The second watches for patterns no single transaction would reveal.

Gate 1: Ingest-Time Validation

Accept, reject, or return with errors

Real-time validation at the point of data arrival. If incoming data fails structural or logical checks, errors are returned to the sender immediately so they can fix and resend. This prevents bad data from ever entering the platform.

  • Format and schema validation
  • Required field checks
  • Value range and referential integrity
  • Immediate error feedback to sender
Gate 2: Ongoing Trend Monitoring

24-hour surveillance across all feeds

Batch quality checks running approximately every 24 hours that analyze trends across the full dataset. Issues are surfaced at the vendor, client/provider, and patient level, catching slow degradation and outliers that no single transaction would expose.

  • Volume and completeness trending
  • Threshold-based alerts by severity
  • Drill-down by vendor, client, patient
  • Outlier detection and impact assessment

Proving data health to the toughest audience

I used this quality infrastructure to demonstrate data health evidence to CMS (the Centers for Medicare and Medicaid Services), showing them precisely why certain data points varied by vendor and provider and shouldn't be used for national benchmarking without understanding those inconsistencies. The system could surface exactly where data mapped cleanly across integrations and where it didn't, giving regulators the evidence they needed to make informed decisions about data reliability. CMS was impressed enough that the approach influenced how they evaluated data quality across the program.

The systems that made it work

80 / 20

Core vs. Custom Data Strategy

Across 40+ vendor partners, roughly 80% of data elements are structurally the same: identifiers, dates, status codes, transactional records, and dimensional attributes. The other 20% is vendor-specific customization. I design the ingestion layer to normalize the core into consistent definitions via lookup tables and configurable mapping, so analytics treats every vendor's data the same way regardless of how it was originally stored.

700+

Centralized Validation Engine

Separately from the data quality gates, I centralized 700+ assessment validation rules into a shared service consumed by four platform integrations. These had previously been duplicated across five independent engineering teams. Centralizing them eliminated inconsistency, reduced maintenance, and freed those teams to work on higher-value features.

Watchtower

Internal Data Operations Tooling

I built internal tooling called Watchtower that gave non-technical teams (support, customer success, QA) full visibility into data pipelines, processing status, and lineage without requiring an engineer. It supported large-scale data backfills, recalculations, entity construction, and user impersonation for debugging, making data operations self-service for the teams closest to customers.

5x

Productized Specifications

I designed tooling that ingested complex business rules defined in XML specifications and automatically generated corresponding test code, improving engineering velocity by approximately 5x for validation rule delivery. This turned a manual, error-prone translation process into a reusable, machine-readable pipeline.

APIs

Unified Integration Platform

I designed and scaled unified APIs with parameterized endpoints that handled multiple data schemas through the same interface. Developer-first documentation and write-back capabilities made it as easy as possible for vendors to connect. The same API architecture was reused across product lines without re-architecture, and the pattern was replicated at a second company when I built the same integration platform from scratch.

AI

AI-Powered Prototypes

Most recently I built working AI prototypes using Claude and AWS Bedrock for automated data monitoring, predictive risk scoring, and proactive customer retention. These pulled behavioral signals, usage data, and qualitative support patterns through a retrieval-augmented reasoning layer to surface at-risk accounts with 94% accuracy. Functional demos with executive buy-in, not roadmap slides.

The pattern is the same, the domain is different

My background is in enterprise healthcare data platforms, where the source systems are EHRs and the data is clinical. But the structural problem of getting messy, inconsistent data from dozens of external partners into a form that analytics and AI can trust is identical across industries.

What I've Built

  • EHR, payer, and hospital ADT integrations
  • Assessment, claims, and survey data ingestion
  • Two-gate data quality monitoring (ingest + 24-hr trend)
  • Entity construction and cross-system linking
  • Multi-dimensional quality scorecards
  • Predictive models on millions of records
  • Data health evidence presented to federal regulators

What This Becomes

  • Retailer POS, WMS, and inventory system integrations
  • Sales, shipment, pricing, and promotion data ind tracking
  • Operational analytics and performance dashboards
  • Demand forecasting and ordering optimization
  • Data health transparency for enterprise customers
