I build AI agents that run in production 24/7, plus the web and mobile apps around them. Recent work: • High-ticket wellness AI agent on WhatsApp (Go + Temporal, WHOOP integration, native Swift iOS app), live with 15 paying clients. • 24/7 self-hosted multi-agent system (Claude Code + MCP) for an agribusiness client: orchestration, tool calling, monitoring. • 900+ hours for a US construction marketplace (~8k MAU): Next.js 15 migration with SSR/ISR/SEO, Flutter apps, Firebase. • ~30 Flutter releases for a streaming platform. What I do: • AI agents & tool calling: LLM orchestration, agent harnesses, RAG, fine-tuning, WhatsApp/chat bots, MCP integrations • Backend: Python, Go, Node.js, Temporal, PostgreSQL, Firebase, AWS • Frontend: React, Next.js, TypeScript • Mobile: native Swift (iOS), Android, Flutter 5+ years shipping software. I co-founded SuperNova Dev and run NexGen Labs, a small software studio. Based in Brazil (UTC-3), good overlap with US hours, available 30+ hrs/week. Send me what you need to automate or build and I'll reply with a concrete plan.
