I'm Paul Mikulskis.I build products people use and fix the companies around them.
People bring me a prototype, or a problem their company is stuck on, and I build or fix it front to back. When the work needs a team, I put one together and lead it from inside the company. Yungsten Tech is my firm, and I'm CTO of Vers1ons.
Text me
Tell me what you're building or what's broken.
The line answers in a minute or two, in my voice, and every conversation comes straight to me.
It's the same kind of line I build for companies.
Live since October 2026
Avocado
Avocado is an AI partner for artists and their teams, on its own number in iMessage. It knows an artist's deals, releases and team, and nothing in their private thread reaches a group chat until they say yes. It's a Vers1ons product. I built it myself, front to back, on site with Warner Music Group's team.
Products, front to back
Someone has an idea, or a prototype that works for exactly one person. I build the product around it, from the app people use to the servers, the billing and the launch chores, like getting phone carriers to approve a company's texts.
DepthChartIQ started as a founder's prototype, a Python app running on real player data. I rebuilt it into a production app with billing in about nine weeks. CardCanner, a texting service I run myself, had carrier approval by day five and an iPhone beta by week ten.
It helps that 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 iPhone lines or a link to someone's bank, I can build it in.
Fixing what's stuck
I fix the things around a product that hold a company back, like billing that isn't live yet, a cloud bill that keeps climbing, or a launch that needs a security review first.
At FlipSmart, which I co-own, I took billing live. Then in May its bill for Redis, the fast cache in front of its database, came in at nearly thirty times April's. I counted every command, found that nearly half came from one cache, fixed it, and moved Redis to a server FlipSmart runs itself, with a flat monthly bill.
Before TradeCanny's public launch, its founder asked me for a review he figured would take two hours. It turned into nine phases of changes that tightened security on payments and data access.
Teams inside the company
When a company needs a technical team it doesn't have yet, Yungsten Tech puts one together from people I've shipped with. I lead it from inside the company, in its repos and its chat, next to its own people. I set up each codebase so people other than me can ship on it, and the work keeps moving when I step back.
I built the Vers1ons engineering team and gave each engineer a part of the product to own. They write most of its code now. DepthChartIQ's CEO merged his first pull request when the repo was nine days old. In July he merged more than I did.
Up next: running a company's IT and security
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 is a list of where every password, key and admin login lives, and who can use each one. Then it all moves into managed tools, so the company controls access from one place, and the routine work gets automated.
At the end, the company has a setup that runs, and its own people understand it.
