Healthcare AI, SaaS architecture, and GHL automation. FDA-adjacent, HIPAA-aware, production-grade.
How I can help
I work with founders and teams in three steps, shaping the idea, shipping production AI and SaaS, then growing without fragile rewrites.
Strategy & architecture
I help you sharpen the problem, trim scope to what actually ships, and design the stack, AI agents, RAG, voice, data, integrations, and hosting, into a roadmap you can fund and execute.
Build
I implement production-grade software end to end: Next.js UIs, Node or Python backends, AI and voice pipelines, auth, Stripe, CRM hooks, webhooks, and observability, not demos that collapse under real traffic.
Scale & iterate
Once you are live, I keep you moving, performance tuning, automation (including N8N), reliability fixes, security-minded hardening, and new features, so growth does not force a risky rewrite.
