Yungsten Tech · CTO of Vers1ons · Boston

From here to a product that moves minds.

I work out what the business really needs and build it, front to back, so people use it.

  1. Hey Paul, found you on mikulskis.techDelivered
  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.

Four ways in

Which one sounds like you?

New work goes through my firm, Yungsten Tech.

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

I finish it and take it live.

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.

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

Not quite you?

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.

Not quite you?

You need engineers in your codebase now.

Engineers ship in your code, then your own team takes it over.

Yungsten Tech puts the team together, and I run it from inside your company, in your code and your chat. I give each engineer a part of the product to own and set up the checks every pull request runs. Then I hand it over. How I've handed code over before →

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.

After you text

What happens next

  1. You tell me what you need

    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, and if it needs a team, Yungsten Tech puts one together. 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

    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 updates itself while I build, so you can check where things are without asking.

  5. Your team runs it

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

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 iMessage number, and I build what answers on it. Outside Vers1ons, I build these through Yungsten Tech.

Now

Updated Nov 3, 2026

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

In October, 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.
