Email list cleanser

Before you upload contacts to Marketing Cloud Account Engagement (MCAE), you need to know your data is clean. Invalid emails break automations. Field length violations cause import failures. Duplicate records waste budget.

This tool validates everything before import—email format, field limits, data quality, duplicates, and more—and processes everything right in your browser.

Best of all, your contact data never leaves your computer. Fix issues with inline editing, apply bulk corrections, and export clean lists ready for MCAE.

Side projects

Hummelify

Interactive website I built using Claude Code. Upload a selfie and it removes the background, creates an AI version of your face in the likeness of a Hummel figurine, and emails it to you.

I made this as a proof of concept for creating beautiful Typeform-esque forms using AI tools.

iOS Shortcuts

I use the Apple Shortcuts app to make my life easier. I run them on my HomePod, Apple Watch, and iPhone. These examples show my innate sense of “curiosity, tinkering and hacking”—and they are cool.

Even older stuff

Do ideas really spread like viruses?

This is the capstone project I made for my Master’s degree at University of Pennsylvania. I interviewed a bunch of people and made an interactive website for it.

Some of it is broken now. Check it out anyway?

bminus

bminus was a bicycle apparel company founded by a friend and I in 2004, with a simple idea: a t-shirt with two people on a tandem above the words “bicycles are for lovers.” Hundreds of t-shirts later, bminus mailed its last hand-packed parcel in 2011.

Reminisce with us, won’t you?

Testimonials

Neha Patel, VP of Finance, CardFlight

I worked with Marc at CardFlight and always appreciated how easy he was to partner with. He has a great balance of creativity and practicality, and he consistently found ways to move projects forward in a way that actually worked for the business and the team.

Marc is also an excellent communicator. He had a real knack for putting complex ideas into clear, straightforward updates for a group like Finance, which made decision-making faster and smoother for everyone. On top of that, he was always willing to roll up his sleeves and help out—even with projects that were a little undefined or outside of his “official” scope. You could always count on him to step in, bring structure, and get things done.

He’s the kind of teammate who makes work both more effective and more enjoyable. Any team would be lucky to have him.
