I build SaaS products end-to-end — from the first line of code to live, paying customers. I'm a full-stack developer focused on Node.js/TypeScript backends, browser extensions, and clean AI/LLM integrations. I recently designed and shipped my own SaaS product: an AI-powered browser extension that summarizes YouTube videos, with a working subscription system and a custom payment stack supporting both fiat and crypto worldwide. I owned every layer — architecture, backend API, the AI pipeline, billing, and deployment. I don't just close tickets. I think about the whole product: security (no secrets exposed client-side), robust payments (idempotent webhooks, no double-charging), and infrastructure that stays up. I take on small and mid-sized SaaS work as well as full builds — a focused feature, an integration, a bug-hunt, or a complete MVP. If you need someone who can own a piece of a product and deliver it properly, let's talk.
