I write the parts of your Webflow or Framer site that the platform can't do on its own.

What you get

The feature. Built as a Webflow embed or a Framer code component, responsive and tested across browsers.
The parts your team controls. Text, images and settings stay editable in Webflow or Framer, without touching code, wherever the feature allows.
The parts that connect. APIs, CRMs, job boards and data feeds wired in, with caching where it matters.
The parts nobody sees. Scripts that load only where they're used, so the page stays fast, and documentation for whoever maintains the code next.
After launch. Two weeks where I fix anything that turns up.

Recent works

Live job listings for Grindr. The careers page needed open roles from Ashby. Webflow has no Ashby integration, so I wrote one.
Donation forms for Nature Sacred. Their donor CRM's forms weren't built for Framer, so I built components that match the design and drive the CRM's real forms underneath. Every gift still lands where it should.
Pages that open like folders for Village Global. Webflow doesn't support it, but I came up with a solution.
A crowded map for Nature Sacred. More than half of its 200 Sacred Places sit in Maryland and DC, so I built labels that move the packed East Coast states into a tidy column over the Atlantic.
An interactive timeline for Sphere. A company history told along a horizontal timeline, with animation tied to scroll.
"If you've ever wanted to have the best dev who will go the extra mile and makes the impossible possible, you have to hire Roman." — Jesse Daniels, Traffick Media

How I work

Before any code, I write a short plan: what the feature does, how it's built, and what it depends on. We agree on it, then I build. If something really can't be done inside Webflow or Framer, you'll hear it in the plan, along with the solution.
I'll send you a working prototype early, so you can try the feature before it's finished and there are no surprises at the end. I'm easy to reach and quick to reply.
A custom feature can take from an hour to a week, depending on the scale of the task.
I have a computer science degree, and I'm a Webflow Premium Partner and a certified Framer Expert. I lead the build; my team helps with production.
"He worked through a complex build like a boss, and pushed hard to meet deadlines. We'll work with him again." — Gonz Sanchez, Carrara

What I need from you

A description of what the feature should do, and a design if you have one. Access to your Webflow or Framer project. Logins or API keys for any service it connects to.

If this isn't quite it

Need a whole site built from a design? See Figma to Webflow or Figma to Framer — Multi-Page Website Build. Need the design as well? See the Design + Build services.
Send a short description of the feature and a link to your site. I'll come back with my questions.
