About Lucas
Full-stack developer and AI automation specialist working with startups and brands in the US and European markets.
I build production-ready products: React/Next.js marketing sites and SaaS dashboards, Node.js backends and REST APIs, AI agents and chatbots powered by the Anthropic Claude API, and workflow automations using n8n and webhooks.
My work is live in production - including DMBooked, an AI receptionist platform for aesthetic clinics built on Claude API + n8n, deployed and active.
I work async, communicate clearly, and deliver clean, maintainable code. Ideal for founders and teams who need a reliable technical partner, not just an executor.
Stack: React · Next.js · Node.js · TypeScript · Tailwind CSS · Supabase · Vercel · Claude/OpenAI API · n8n
