I build the tools that make
marketing automation
actually work.

Senior Software Engineer and Marketing Technology Leader. Eleven years at Wunderkind — grew from email developer to lead engineer, four of those years leading engineering teams. Ship triggered programs across SFMC, Responsys, Marketo, Klaviyo, Acoustic, Sailthru, and Zeta — plus the internal tools that move them faster.

Engineering automation that ships

At Wunderkind I’ve designed and shipped a handful of internal tools that materially cut the time Professional Services spends on enterprise onboarding, ESP migrations, and QA. Each one was adopted by the team and measurably saves hours per use.

~22h
saved per client implementation

Onboarding suite provisioning

One-click provisioning of complete Wunderkind campaign suites — emails, data extensions, and journeys — in seconds. Standardized quality across the team and eliminated manual setup for every new enterprise client.

~8h
saved per setup or duplication

SFMC account automation

Creates data extensions, triggered sends, and email messages, inspects live SFMC data, and duplicates entire account assets across instances — enabling fast ad-hoc operations that previously required manual rebuilds.

~3h
saved per QA pass

Link & URL validation

Rapidly QAs onsite and email links at scale to safeguard product integrity during launches and migrations. Catches broken redirects, stale UTMs, and 4xx/5xx responses before they ship.

~2h
saved per journey vs. manual setup

Template-driven journey deploys

A faster, template-driven alternative to Salesforce’s native Journey Builder. Reusable events and direct fetch/deploy bypass the SFMC UI’s latency, with multi-account parametric deployment baked in.

Tools are internal and proprietary to Wunderkind — happy to walk through architecture, trade-offs, and adoption metrics in conversation.

Lingo — ESP dynamic content translator

A side project I built and shipped. Paste personalization logic in any ESP’s templating syntax and Lingo translates it across all five major platforms in real time — with syntax highlighting and confidence indicators where a clean 1:1 mapping doesn’t exist.

Lingo — multi-pane ESP translator with side-by-side syntax outputs for AMPscript, Klaviyo, Braze, Responsys, Iterable, HubSpot, Mailchimp, SendGrid, Mailgun, and Bloomreach
SFMC AMPscript Klaviyo · Django Braze · Liquid Responsys · RPL Iterable · Handlebars + HubSpot, Mailchimp, SendGrid, Mailgun, Bloomreach

Real-time bidirectional translation, confidence warnings for platform-specific features that need manual rewrite, an example library covering common patterns, MIT-licensed, no backend.

Email Development

Emails I’ve coded

Production campaigns I’ve shipped via Wunderkind for global retail brands — responsive, accessible HTML/CSS across Salesforce Marketing Cloud, Responsys, Klaviyo, Zeta, and more, tested across every major client and device. Each card opens a live preview with a toggleable source view.
