Summary
Computer-science graduate and Fortune 50 lead designer who ships complete products end to end — seven live on the App Store, the Figma Community and GitHub — with Claude Code and Codex as the primary development environment. Intent coder: precise briefs, small verified changes, lean token budgets, and the AI tooling itself treated as engineering.

Claude Code engineering — tooling built on Claude Code itself
- Model routing for Claude Code — github.com/arritgashi/claude-code-model-routing. Subagents pinned to Sonnet, Opus or Fable by task, an escalation ladder where a failed attempt climbs one rung, and a /routing-usage skill that charts tokens per model.
- Write-boundary hooks. PreToolUse hooks on Write/Edit and Bash/PowerShell refuse any write outside the project — 216 deny rules, a 23-case regression battery — so one repo can read 50+ sibling repos and never modify one.
- Honesty-rule research agents. A metric must exist in the repo, “shipped” means a stranger can use it today, a link goes live only after it resolves. Read-only agents verify; the main thread is the only writer.
- Multi-agent audits. Fan-out finders plus an adversarial verification pass; the PollXYZ run put 57 agents on the codebase and returned do-not-ship before launch, not after.
Shipped
A classic card game for phones: play a friend, team up two against two, or take on ten AI opponents.
- Took over Stepico's game and rebuilt it in 12 days with Claude Code; my own .NET server owns every coin. ~20k downloads.
Turns a mortgage or real-estate professional's contact book into a ranked daily call queue.
- Three products on one engine; contacts encrypted on-device under a key sealed into two lock boxes, so the operator holds only ciphertext. Nine subscription tiers, three languages, zero third-party SDKs; cleared three App Review rounds.
Tells a home gardener what needs watering today, in one notification, entirely offline.
- No account, no backend: pure-TypeScript product logic, tested before any screen existed. 308 unit tests including a simulated year of reminders across six climate regions; a contrast script gates the build on WCAG; three languages.
A Figma plugin that pastes HTML and Tailwind in as real layers, and turns any frame into an AI brief.
- Converts pasted HTML, Tailwind or CSS into native Figma layers — auto-layout, gradients, shadows, fonts, SVG — and walks any frame into a structured brief for a coding model. 13k lines, zero dependencies, no build step; a cleanup pass cut ~580 dead lines.
Self-hosted image moderation that runs offline, and corrects a documented bias in the model it depends on.
- Two models behind one verdict — a NudeNet detector on the full 104 MB weights plus a Falconsai transformer — with a three-stage pipeline compensating a ~3× documented bias. API, Gradio UI and batch CLI off one core; four framework integrations.
An offline answer engine that looks facts up and refuses to guess — no model, no network, no invention.
- Retrieves, never invents: a zero-dependency TypeScript engine that refuses structurally — a country has no height. Fuzzy matches answered wrong 0.47% of the time, so that path was removed, not tuned; 188 golden queries in CI allow zero false hits.
In progress
Halbreven
In progressExpo · Supabase + RLS · iOS / Android / web · 2026Replaces the group chat for recreational sports: ratings, balanced teams, and reliability you can see.
- The security model is the database. Row-level security on every table through security-definer helpers; multi-table writes are stored procedures on tables with no insert policy, so a half-created group is unrepresentable.
- Anonymity by structure, queue by derivation. The ratings table has RLS enabled and zero policies; the waiting list is one nullable column — order by sign-up time, take the first N — no renumbering job, no lock, no race.
BRAIN
Complete · unpublishedElectron · React · transformers.js · 2026An encrypted personal knowledge base that runs entirely on your own machine, with no server and no account.
- Encryption that fails closed. XChaCha20-Poly1305 under an argon2id-wrapped data key, each ciphertext bound to its row and field so a moved blob refuses to open; a passphrase change re-wraps the key, not the corpus.
- 20 evaluation suites — one caught a real plaintext-export leak, closed by making the export firewall an allowlist. P-256 challenge signatures verified offline by a single HTML file; two runtime dependencies.
A city-scoped opinion polling app where the demographic result, not the user, is the product.
- Pre-launch security audit as a 57-agent workflow — reconnaissance, nine parallel finders, adversarial verification of every finding: 46 raw, 43 verified, 3 refuted, 23 distinct vulnerabilities (2 critical). Verdict: do not ship.
- Remediated from findings, not the roadmap. Both criticals closed, four batches of database patches, three edge functions rewritten; one-device-one-vote moved from the client into a server-side procedure.
