Your stuck product goes live, and your own people keep it that way.

Products usually get stuck because nobody's pinned down what the business really needs, so I pin that down and build it. When a company needs engineers, my firm, Yungsten Tech, puts the team together and I lead it from the inside. I'm also CTO of Vers1ons, a marketplace where music gets licensed for remixes.

  2. Hey, thanks for texting. What are you building, or what's broken?A real reply from this number

This number usually answers in a minute or two, in my voice, and every conversation comes straight to me. I build the same kind of line for companies, on their own numbers.

Which one sounds like you?

You've got a half-built product and nobody to finish it.

It goes live in production, front to back.

Maybe it's an idea, or a demo that isn't a product yet. I build the whole product around it. That means the app people actually use, the servers, billing if you charge for it, and launch chores like getting phone carriers to approve your texts. And it's set up so it stays yours, down to the accounts and keys.

When a product needs a company's spend data, its own iPhone numbers or a link to someone's bank, I build it in. Yungsten Tech is a Ramp embedded partner, a Sendblue partner and a Plaid-approved connector.

Something's stuck, or a bill keeps climbing.

I find what's holding it up and fix it.

Maybe billing isn't live yet, or the cloud bill jumped and you can't tell what's eating it. Or the launch is waiting on a security review. I find the cause and fix it, then tell you in plain words what changed. I work right in your repo and your chat, so your team sees every change.

You need engineers in your codebase now.

A team ships in your code, and your people take it over from there.

Yungsten Tech puts the team together, and I run it from inside your company, in your code and your team's chat. Then I hand it over. Who ships the code now →

Asked for · IT and security

You're not sure who can get into what.

An HR advisor asked me to lead a small technical team that would sit inside a company the advisor works with. That team would take over the company's IT and security.

The first job would be a list of where every password, key and admin login lives, and who can use each one. Then it'd all move into managed tools, so the company controls access from one place and the routine work gets automated. At the end, the company would have a setup that runs, and its own people would understand it.

iMessagenothing for your customers to install

Your product can live in iMessage.

Avocado's demo with fictional people. The artist approves a request to move the final stems to Dec 3. In the label group chat, Avocado confirms the new date and points out that the signed agreement still says Nov 14.
Avocado's public page, captured Oct 29, 2026. The people and deals in the demo are fictional.
  • AvocadoAn AI partner on its own iMessage number. It knows an artist's deals, releases and team, and it answers from the signed contracts. Nothing in a private thread reaches a group chat until the artist says yes. A Vers1ons product, built on site with Warner Music Group's team. Live since October 2026.
  • CardCannerPlain texting, on any phone, with no app and no account. Send it a photo of a business card and it texts back the contact, ready to save.

Want one for your reps or your customers? Your company gets its own iPhone numbers, and I build what answers on them. New work outside Vers1ons goes through Yungsten Tech.

After you text

What happens next

  1. You tell me what's stuck

    One sentence is enough. You'll usually get a question back.

  2. I take it from there

    If there's real work in it, I handle it myself. There's no form, and I won't quote you over text. You decide if there's a next step.

  3. I write the plan first

    Before anything gets built, I write down what's there, what changes, and how you'll know it worked. Then I set up your GitHub organization, hosting, database, and keys. For DepthChartIQ that took one evening.

  4. You can watch the work

    My changes run through automated checks and a review by a second AI model before I decide what ships. You get a status page that refreshes from the running system during the build, so you can check where it is without asking.

  5. Your people run it

    I set it up so your team can keep shipping, and I'm still on call.

Updated Oct 30, 2026

This week, Avocado went live. It's the newest product at Vers1ons, where I still ship code for the platform nearly every week and run the team that ships the rest.

Yungsten Tech is taking on new work. If you're building a product, or something at your company is stuck, text me.
