NULL

One operating platform for any business, delivered as a ready-made edition for each field: 23 editions on one engine, each one app with Owner, Boss and Staff inside, on desktop, iPad and iPhone, kept in sync.

A new edition is a pack, never a fork: each field swaps in its own records, rules and vocabulary on the same core.
White label: convert an edition inside the app, or ship a client-branded build under the client's own name.
Rules that block, not just remind: trust-account hard stops for law firms, live staff-to-child ratios for daycares, witnessed controlled-substance logs for vets.

NULL Labs · Klein Photo Studio

SK Direct

A studio app and a client app on one server, built for photographer Steven Klein. Money moves between them in real time.

A client's purchase lands in the studio's feed and ledger the second it happens.
Every sale carries its real fee, Apple's 15% or Stripe's 2.9% + 30¢, with sales tax held apart.
An invoice sent from the studio shows up in the client's checkout.

MILK App Inc. · Founder

MILK

An ecosystem for gay life: seven modes in one app, on one shared map, each with its own privacy rules. Launching in New York in January 2027. I lead product, design, the frontend and the backend.

Built onOne appOne shared mapOne design systemOne backend

MILK main menu: Connect modes Hookups, Anonymous, Dating and MILK Cellular, and Discover modes MILK Services, Community and Resources. — **Menu** · seven modes, one app

Hookups grid: members nearby sorted nearest first, with a row of who's online, a duo tile and distances. — **Hookups** · nearest first

StealthSquare map in Chelsea: a burn timer, busy venues and member counts on a fuzzed map that never shows an exact block. — **Anonymous** · counts only, never the block

Dating, Today's Four: four profiles a day with relationship styles and distances. — **Dating** · four a day

MILK Cellular setup: a second eSIM number with a plan, an area code and an emergency address for 911. — **Cellular** · a second number

MILK Services, Advertise: a vetted-ally verification banner, a business listing form, categories and flat-fee plans. — **Services** · flat-fee listings

Community feed in Chelsea: advice, events and fun posts with votes and replies. — **Community** · local feed

Resources: crisis support lines, search, and categories from health to housing, with no account needed. — **Resources** · no account needed

Privacy by mode: Each mode sets its own rules for location precision, identity and data retention. Anonymous sessions are never linked to your main profile, show only counts in fuzzed zones, and end in a verified burn. Resources needs no account at all.
One design system: 22 Figma pages and 1,750+ frames, translated into one token file. Every mode shares the same layout, header and navigation and brings its own accent and nav slots, so seven products read as one app.
Money: Paid tiers sell time and placement, never safety. Business listings are a flat monthly fee with no commission, and Cellular is a monthly eSIM plan.
Trust and verification: Providers are checked against state license registers, or ID-checked, before they get a badge. A Cellular line needs a 911 address before it turns on, and only dispatch ever sees it.

Engineering

I build what I design

I work from Figma to tokens to shipped code. I led the frontend and the backend, and I ship builds to TestFlight. I use AI-assisted engineering tools, and I know where the human-written code has to live.

Interface: TypeScript, React, HTML and CSS
Mobile: React Native, SwiftUI, iOS and Android
Graphics and motion: WebGL2, GLSL, Reanimated, Canvas
Design systems: Design tokens, OKLCH color, JSON-driven UI, Figma to code
Backend: Node, Express, Postgres, REST and sockets
Cloud: DigitalOcean droplets, Linux, SSH deploys
Shipping: Xcode, TestFlight, fastlane, GitHub Actions
Privacy: End-to-end encryption, WireGuard tunnels, hash-chained audit logs
Retouching: Photoshop, Capture One
AI assistance: Claude, Grok

LocationFuzzer.tsx MILK app · src/app/components/shared/mapview

  const panGesture = Gesture.Pan()

    .activeOffsetY([-5, 5])
    .failOffsetX([-15, 15])
    .onBegin(() => {
      dragStartOffset.value = thumbOffset.value;
    })
    .onUpdate(event => {
      thumbOffset.value = clampPosition(
        dragStartOffset.value + event.translationY,
        0,
        THUMB_TRAVEL,
      );
      const currentValue = positionToValue(
        thumbOffset.value,
        minSV.value,
        maxSV.value,
      );
      scheduleOnRN(emitValue, currentValue);
    })
    .onEnd(() => {
      const snappedValue = positionToValue(
        thumbOffset.value,
        minSV.value,
        maxSV.value,
      );
      const snappedPos = valueToPosition(
        snappedValue,
        minSV.value,
        maxSV.value,
      );
      thumbOffset.value = withTiming(snappedPos, { duration: SNAP_DURATION });
      scheduleOnRN(emitValue, snappedValue);
    });

From the MILK app's map. The privacy slider's drag runs on the UI thread as Reanimated worklets: the thumb clamps to its track, each whole step reaches React once, and release snaps to the nearest step in 80 ms.

Craft

The eye came first

I've retouched fashion, advertising and editorial work since 2018, including Steven Klein Studios since 2020, and I direct AI-generated campaigns and films. That eye for a single pixel is what I bring to interfaces and motion.
