Work

Things you can go and look at.

A help center that maintains itself. An LMS built in three weeks instead of nine months. Learning platforms serving hundreds of millions of people. Most of it is still running.

Live now · built 2026 replit.com/help

Replit's help center. I designed it, built it and shipped it, backend included, writing the code myself. It rebuilds and republishes itself every night from a continuously maintained source of truth, so it is never out of date.

It's a working version of what I describe everywhere else on this site: knowledge with a lifecycle instead of a publish date. Go look at it.

Replit · 2026

An LMS in three weeks, not nine months.

LaunchPad, the learning platform Mark built at Replit

The situation. I've implemented five LMS and LXP systems across my career, and helped build one at Microsoft. The pattern never changes: months of RFPs and evaluations, a $500K+ investment, then three or more months of configuration and bespoke code before anyone learns anything. The right solution is never out of the box.

What I did. At Replit I designed one from the ground up and had a working beta in three weeks. I'm a learning person, not an engineer. I wrote the plan in plain English, the way I'd walk a new teammate through it, and built it prompt by prompt.

Where it got to. It now runs onboarding end to end: personalized learning journeys, hands-on practice, a living knowledge library, progress and feedback, analytics and reporting. It improves weekly, shaped by the people learning on it. It doesn't have a thousand features. It has theirs.

When someone hits a wall in the morning, it's fixed by the afternoon. No quarterly roadmap, no vision deck.

Microsoft · Enterprise

$10M a month, by helping people answer their own questions.

Microsoft 365 help and learning, still running today

The situation. Support volume was overwhelming the organization. Every question a customer couldn't answer for themselves became a ticket someone had to work.

What I did. Led the team that built customer-facing learning across every Office audience, device and platform. Managed 20 staff and 70 vendors. Increased video output 300% and training output 200% by rebuilding the production workflow. Launched the first ever Microsoft–LinkedIn Learning collaboration.

The result. 330M monthly learners, and $10M a month in support cost reduction as people found answers instead of filing tickets. The site is still running today.

Replit · Free Mode

Twenty minutes, zero dollars, a working chief of staff.

Daily Compass, a personal planning app Mark built in twenty minutes

Daily Compass pulls my meetings from Google Calendar, unread follow-ups from Gmail, active issues from Linear and note prompts from Granola into one view, then builds a prioritized Top Three. In the evening it walks me through what actually moved, what I did that wasn't planned, and which parked ideas get promoted into tomorrow.

I built it in twenty minutes for nothing, because I wanted it. The gap between "I wish I had a tool that…" and having that tool is essentially gone. That's the shift I help companies act on, and most of them haven't internalized it yet.

Independent · Live

A product of my own, shipped end to end.

Six Second Resume, an AI resume product Mark built and launched

Six Second Resume scores a résumé against a job posting, finds the missing keywords and returns an ATS-ready version in under three minutes. I designed it, built it, wired up payments and email automation, and launched it. It earns while I sleep.

Nobody asked me to build it. That's rather the point.

Also built

Earlier, and at scale.

Microsoft · Platform

Microsoft Virtual Academy

Built the platform and the team. 4.5M registered users, 1.5M unique monthly visitors, 2,000+ courses, developer engagement goals beaten by 132%. Digital learning before it was a category.

Microsoft · Migration

Microsoft Learning Experience

Designed and launched an Azure-based learning platform, then migrated 5,000+ SCORM courses onto it without losing the catalog.

Fortive · AI, 2018

ML translation pipeline

Cut content localization costs 5–20x with machine translation, years before this was a category. L&D strategy and governance across 400+ global brands.

Four companies

The function, from scratch

Built Learning & Knowledge from nothing at Fortive, REEF Technology, DoubleVerify and Replit. Different industries, same problem, every time on a cost-center budget.
