Hire the Best ActionScript Developers
in the United States

I build reliable automation that replaces manual, error-prone work — Playwright browser automations, JSON-driven data-entry systems, Electron desktop distribution, Shopify and Amazon workflows, and typed AI systems that stream reasoning instead of hiding behind a black box. See full work portfolio at MichaelCozart.Dev I’m the founder of COPYCRAWLER LLC and I publish consumer iOS apps under it — two live in the App Store (Case Law Search and Videotokitchen), a third in development. That matters here because it means when I quote an automation or a workflow build, I’m quoting from someone who has actually shipped and maintained real products, not someone who has only built demos. What I typically ship for clients • Playwright browser automation — production apps like Service Autopilot, Amazon Seller Central, and internal SaaS portals. Stable selector engineering, app-shell waits, debug capture on failure, Zod-validated JSON input contracts, and explicit human-commit steps so operators keep control. • Electron desktop packaging — automations distributed as signed Windows / Mac builds via electron-builder, so your team runs them locally instead of paying for hosted browser infrastructure. • Amazon Seller Central workflows — multi-SKU bulk-upload templates with pre-flight validation, A+ Content, backend search terms, and compliance-safe listing copy (I run a live ASIN under my own LLC, so I know the constraint set). • Custom Shopify Liquid theme engineering — hand-authored sections, JSON-LD product structured data, and Core Web Vitals discipline. Not drag-and-drop template retrofits. • Typed AI systems — BAML-typed LLM function contracts, streaming outputs, multi-provider routing, and Pydantic AI pipelines. AI that ships with real telemetry, not just a prompt in a text file. • Full-stack web apps — React + TypeScript + Supabase (RLS) + Playwright E2E tests. Strict mode, ESLint, Zod validation everywhere. I don’t ship prototypes — I ship apps with tests. Selected recent work • Service Autopilot job entry automation — Playwright + Zod + XLSX + Electron desktop packaging • MarketplacePricing V1 — Express + BAML typed streaming LLM functions + Netlify Functions • Lord’s Love Butter Shopify theme — ~950 KB of custom Liquid, JSON-LD, Core Web Vitals tuning • Case Law Search (iOS, live) — native Swift + paired TypeScript/Supabase search index • Videotokitchen (iOS, live) — native Swift + LLM transcript-to-recipe pipeline • Landscape Whisperer Bot — TypeScript + Supabase + Zod + Playwright E2E harness • PDF Presenter — jspdf + html2canvas + Supabase + Playwright presenter flow tests • Durable Video Distribution Pipelines — Upstash Workflows + Mux + Shotstack + AWS S3 How I work • I read the actual code and the actual constraints before quoting. • I write down selectors, validation schemas, and failure modes so anyone can maintain what I build after me. • I keep humans at the commit step for anything irreversible — automations verify, humans commit. • I don’t ghost. If something takes longer than I said it would, you hear about it before the deadline, not after. Fit / no-fit Great fit for: workflow automation projects with a real underlying business process, Amazon and Shopify commerce engineering, AI product builds with real reasoning surfaces, iOS app work, and any project where the previous freelancer left you with a half-finished prototype and no tests. Not a fit for: pure design work, WordPress theme customization, or projects where “just get it working” means skipping input validation on data that touches money or public listings. Let’s talk about what you need built. Attach a spec or a Loom, tell me what “done” looks like, and I’ll tell you exactly what I’d do differently and how long it’ll take.
