Bio
Tyler is a senior full-stack engineer with over 10 years of experience solving hard problems across startups, enterprise modernization, healthcare, and B2B SaaS. He's a broad generalist who goes deep wherever a project needs it: data pipelines, back-end APIs, front end, and cloud operations. Most recently, he's built agentic AI search platforms at Scalis and Fishbowl. He's the person you bring in to own ambiguous, high-stakes work and get it done.

Experience
Supabase AI Starter Kit
https://github.com/fletchertyler914/supabase-ai-starter-kitThe Supabase AI Starter Kit is a complete local AI product stack, including:
• Supabase self-hosted for auth, PostgreSQL, Pgvector, real-time, storage, and edge functions.
• Kong as the API gateway in front of the Supabase services.
• n8n for visual workflow automation, seeded AI agents, and workflow templates.
• Ollama for local chat and embedding models.
• Docker Compose for repeatable local development, demos, and single-server deployment.
• Validation scripts and CI so you know the stack still works after you change it.
The goal is simple: skip the infrastructure tax and start building the actual AI product.
