I build products end to end — architecture, code, infrastructure, and the store listing.

Founder of Staberman, a one-person studio where I ship software for clients and my own products.

_{Extracted from the products below — and the part of my work you can read, run and check without taking my word for it.}

SplitFlap — mechanical split-flap departure board components for SwiftUI, extracted from Pomotti. Tiles flip, rows spell themselves out, and a Canvas fast path keeps a large board at frame rate. MIT.

ntag213-ndef — NDEF bytes that iOS background tag reading actually accepts, plus an NTAG213 lock verifier that reads page 02h instead of the one that misleads you. Zero dependencies. MIT.

app-attest-gate — the parts of Apple App Attest everyone hand-rolls wrong: single-use challenges, atomic replay protection, per-assertion environment pinning and request-body binding, paired with StoreKit 2 entitlements and a server-metered free tier. MIT.

AppAttestClient — the Swift half: a Secure Enclave request signer whose concurrent registrations collapse into one, so a fresh install cannot race itself into a 401. MIT.

📱 iOS & macOS Three apps built solo and submitted to the App Store — a Pomodoro timer styled as a split-flap departure board (SwiftUI, iOS + iPadOS + macOS), a mind-dump journaling app with an AI backend (SwiftUI), and a personal expense tracker with native StoreKit 2 subscriptions (React Native / Expo).

🏗️ Multitenant SaaS A marketing analytics panel on Next.js 16 and self-hosted Supabase: row-level security across a five-role tenant hierarchy, batched ingestion that collapsed 9,000 API calls into 18, cron-driven alerting, and 1,229 passing tests.

⚡ Commerce & automation Digital storefronts running in production with paid acquisition on Meta, a WhatsApp sales bot with its own CRM, and an outbound prospecting pipeline that has worked 700+ leads unattended.

🧾 Client work An offline-first point-of-sale PWA for a restaurant, built to keep taking orders when the network drops.

I work in hexagonal and screaming architecture, with tests that describe behavior instead of implementation. Most of what I build is meant to be maintained for years, not demoed once.

Specs before code. Every non-trivial change starts as a written spec, a design, and a task list — then gets implemented and verified against them.

Review is a gate, not a ritual. Nothing reaches a commit without passing an adversarial review pass.

Production is the only real test. I run my own infrastructure, so I find out what breaks before a client does.
