Marketing Technology Solutions Architect

I architect the marketing stack — and then I build it. Enterprise ESP architecture, email infrastructure, and deliverability at network scale.

About Me

I close the gaps that stall marketing technology.

Most martech architecture stalls between people. The integration waits on a developer. The email system waits on a designer. The reporting layer waits on an analyst. Every decision costs three handoffs and three calendars.

I own the marketing technology architecture behind a 100+ university partner network — two enterprise ESPs running in parallel, automation and journey architecture built centrally and deployed across the network, and sender reputation managed at the domain and IP layer. A 100-partner network doesn't fail one brand at a time. It fails all at once. So I don't run campaigns. I run a system.

Then I built the platform itself. Senderhive is a production-grade multi-tenant ESP I architected solo — a visual automation engine, multi-tenant access control and usage metering, a 68-email-client rendering and deliverability-scoring testbed, and AI generation shipped into the product.

Earlier, at AccuData, I designed, built, and deployed email for brands including Outback Steakhouse, Hyatt Regency, Fleming's Prime Steakhouse, BoatU.S., and Nick Alexander BMW — and led the expansion that grew that creative services division 44x.

Eight ESPs operated in production. One architected end to end. I've seen the stack from the buyer's chair and the builder's.

Architecture Without Hand-Offs

Where a typical martech architect needs a second team, the capability is already in-house.

Areas of Architecture

Email Systems Architecture

Design systems, rendering standards, and template architecture at multi-brand scale — one system 100+ brands build inside, not one-off builds per partner.

  • Responsive Email Design Systems
  • Rendering & Dark-Mode Standards
  • Template Architecture at Network Scale
  • Cross-Client QA Instrumentation

Platform & Interface Architecture

Component systems, authoring tooling, and admin surfaces. Interfaces designed against the data model underneath them, not on top of a mockup.

  • Component Systems & Design Tokens
  • Authoring & Editor Tooling
  • Admin & Workspace Surfaces
  • Role-Based Access Control

Sending Infrastructure & Deliverability

Sender reputation, authentication, IP strategy, and multi-domain sending architecture. The layer that decides whether anything else works.

  • IP Warming & Reputation Management
  • SPF, DKIM & DMARC
  • Blacklist Remediation & Delisting
  • Multi-Domain Sending Architecture

Automation & Journey Architecture

Trigger design, orchestration patterns, and reusable workflows built centrally and deployed across a network rather than rebuilt brand by brand.

  • Journey & Workflow Orchestration
  • Trigger-Based Campaign Architecture
  • Segmentation & Personalization
  • A/B Testing & Experimentation

Data & Intelligence Architecture

Schema design, revenue attribution, churn modeling, and send-time optimization — the data layer that makes lifecycle decisions measurable.

  • Schema & Data Model Design
  • Revenue Attribution
  • Churn Prevention Modeling
  • Send-Time Optimization

Full-Stack Platform Engineering

Multi-tenant architecture, API design, data modeling, and realtime infrastructure. I architect the platform and then I build it.

  • Multi-Tenant Platform Architecture
  • REST API Design & Integration
  • MySQL Data Modeling
  • WebSocket Realtime & Auth
Featured Project
