Independent engineer · 30 yrs in production
Something in your business is quietly expensive. Usually it is a job someone still does by hand.
I find the one that is costing you most and build the software that ends it. Thirty years of production systems — streaming, healthcare payments, patient referrals, worker safety, phone networks — and it is the same shape every time. You work directly with the engineer who builds it.
Different businesses, the same broken process
A dental practice, a law firm and a freight company have nothing in common from the outside. Underneath, the expensive part is the same: information arrives in one shape, it is needed in another, and a person sits in the middle.
- Somebody retypes it every day
- The same numbers moved from one screen to another by hand. You are paying for the hours, and it is where the mistakes come from.
- You find out weeks later
- A claim denied, an order never sent, a payment never landed. Nobody sees it until the money is missing and the trail has gone cold.
- It only works because one person knows how
- The real process lives in one person's head. When they are away the work stops, and when they leave it goes with them.
- It stopped fitting a while ago
- It was right for the business you had three years ago. Growing now costs more than it should, and everyone can feel it.

Six industries, one job
Each one was somebody else's expensive problem. Every figure is from the record.
Across those systems
- A synchronous import redesigned onto background jobs and 66 times faster, with the memory ceiling that capped file size gone
- Seventeen-second timeouts brought under a second on searches serving millions of queries
- Improvements of ten to a hundred times in critical production systems
- Twenty-four hours a day, seven days a week, on call for the consequences
From the people who paid for it
Each answers a fair question about hiring one engineer instead of a firm.
Is the AI part real, or is it hype?
I hired Mark to build out a customer portal for us […]. Mark is likely the most knowledgable AI-first programmer I know. Not only did he deliver the project requirements but also taught our team a valuable skill — how to leverage AI agents at scale with custom loops. Our engineering process won't be the same. Highly recommend Mark.
Will it actually land, or will it drag?
I've had the privilege to work with Mark on a recent and successful backend modernization project at SlingTV. Over the course of this one-year long effort, Mark proactively took on some of the most challenging aspects of the solution in languages that he was previously unfamiliar with… contributed directly to the timely delivery of a complex solution with the high performance and quality SlingTV's customers expect.

How this goes
Four steps, and the first one costs you a quarter of an hour.
- A conversation
- Fifteen minutes about what is actually costing you — where the time goes, what breaks, what you have already tried. No form to fill in and no sales call.
- A straight proposal
- In writing: what I would build, what it costs, when it lands, and how we will both know it worked. In plain language, not a deck.
- You see it running, weekly
- Working software every week rather than a reveal at the end. If something is going the wrong way you find out in week one, while it is still cheap.
- It runs without you thinking about it
- Deployed, watched and written down, so your team can pick it up. Or leave it running with me and never think about it again.
