• Founder & Lead Developer · UpTechSwiss05-01-2022

  Founder & Lead Developer of UpTechSwiss, a tech company I run while personally delivering all client work — from architecture to deployment. I primarily build production AI agents and multi-tenant SaaS platforms for clients in Brazil and Switzerland, owning the full lifecycle from discovery to handoff. Key projects delivered: - Sophie — bilingual (Portuguese/French) WhatsApp AI agent resolving ~80% of customer interactions autonomously for a 20-year-old print shop in Geneva, Switzerland - Fazenda OS — multi-tenant SaaS on Supabase for Brazilian agricultural producers, with PostGIS-based geo-referencing and conversational AI on WhatsApp - Premium multi-language marketing sites: UpTechSwiss in 5 Swiss languages (EN/FR/DE/IT/RM) and Évolution Création Graphique with WebXR augmented reality product gallery I operate self-hosted infrastructure (Docker + n8n + PostgreSQL + Redis on VPS) supporting all client automations with 99.5%+ uptime. Available for full-time or part-time engagements. I personally own delivery and client communication — not handing off to a team. Working from Brazil (GMT-4) with full US Eastern business hours overlap. Stack: React, Next.js, TypeScript, Node.js, Supabase, PostgreSQL, Tailwind, n8n, Anthropic Claude API, Evolution API, Vercel, Docker.
