full-stack developer.

Lifetime metrics on Upwork as of 2026: $277K+ earned, 10,000+ hours billed, 242+ projects delivered to production, 100% job-success score, 5.0 average rating across 242 verified reviews.

Founders who need a senior engineer to ship the spine of their product without a hand-holding chain. Operators of growing Shopify stores who need custom theme work, Plus migrations, or bespoke apps. CTOs and product leads who need a SaaS MVP or a production-grade AI feature shipped on a real timeline.

Typical engagement is one engineer (me), one product owner, fixed-price or hourly, with daily commits and weekly Loom demos. No middle layer — you talk to the person building the product.

Shopify, SaaS, AI — end to end.

Three primary categories:

• Shopify stores — custom themes, Liquid, Shopify Plus, custom apps, Hydrogen headless storefronts, third-party API integrations, subscriptions, loyalty, ERP sync. 3 live Shopify projects in selected work.
• SaaS products — Next.js, React, TypeScript, Node, Postgres with Prisma, Stripe billing, Twilio voice/SMS, Nylas email/calendar, AWS S3, multi-tenant data, dashboards. 2 multi-tool SaaS workspaces in selected work.
• AI web applications — LLM-powered tools, OpenAI APIs, retrieval-augmented generation (RAG), AI agents, prompt design, eval rubrics, streaming infrastructure that holds up in production.

Plus marketing sites on Webflow and WordPress when a content site is what's actually needed.
