About Marcel Francis

I help startups and established teams transition to the AI-native era, combining deep backend expertise with advanced AI orchestration and scalable automation.

With years of hands-on experience across the stack, I specialize in:

  • Building modern serverless architectures (Supabase, Cloudflare Workers, AWS Lambda)
  • Migrating legacy systems (Firebase, Django) to next-gen tech like Supabase & Next.js
  • Designing automation pipelines and agentic workflows using tools like n8n, Python, Redis, and RabbitMQ
  • Implementing robust LLM-based systems: GPT fine-tuning, multi-agent orchestration, memory modules, natural language interfaces, and human-in-the-loop validation

Whether you need to ship a scalable MVP, overhaul your backend, or embed intelligent automation into your product, I bring a generalist’s brain and a specialist’s execution.
