What I help teams build

From greenfield products to high-traffic refactors, I bring a full front-end practice: system design, implementation, and the operational habits that keep quality high after launch. Each engagement is scoped in writing before any code is written.

01 / Production App Router builds, front to back

Next.js application development

Full application work on the App Router — routing, data layer, auth, and the deploy pipeline — built to stay fast and maintainable past launch.

02 / Design systems and complex interface work

React frontend & UI systems

Design systems, component APIs, and the hard interface problems — forms, tables, data-dense views — built to scale with your team.

03 / Wallet flows and on-chain UX that survives the unhappy path

Web3 product interfaces

Marketplaces, minting, and wallet-connect UX designed around failure — pending transactions, rejections, wrong network, gas spikes.

04 / Back offices, dashboards and operator workflows

Custom admin & internal tools

CRUD back offices, operations dashboards, and internal tooling with search, permissions, exports, and layouts built for people who use them all day.

05 / Documentation sites and developer-facing content

Docs & learning surfaces

Documentation sites and learning surfaces with real information architecture, working search, MDX, and multi-language support.

06 / Speed, WCAG compliance, and the last 10%

Performance, a11y & polish

Targeted work on load performance, Core Web Vitals, WCAG compliance, and the interaction polish that makes a product feel finished.

How engagements run

Scoped, sliced, and handed back

STEP 01

Discovery

We align on goals, constraints, and success metrics, then turn that into a practical scope.

STEP 02

Build

I ship in small, reviewable slices with performance, accessibility, and clean architecture in mind.

STEP 03

Refine

After launch, we tighten UX, polish edge cases, and keep velocity high without quality regressions.

Full detail on cadence, communication, and what I need from you is on the process page.

Not sure which one fits?

Send a two-line description of the problem. I'll tell you which of these is the right shape of engagement — or that it isn't one I'm the right person for.
