About Me
Your engineering partner
I’m Mac Huang, an AI systems architect and senior full-stack engineer based in the Greater Toronto Area, with roughly fifteen years building production software — including enterprise financial platforms at major Canadian banks. Today I focus on applied AI: designing multi-agent LLM systems and the full-stack engineering that takes them from architecture to production. My flagship project, FinMRI, is a multi-agent equity-intelligence platform that turns institutional-grade analysis into a clear, attributable report. Rainbow After Storm is how I bring that work to clients — pairing deep engineering with the judgment to ship systems that hold up in the real world.

Why Work With Me?
Dedicated to your success with full focus
- Goal-oriented;
- I focus on delivering systems that hold up in production, not just theoretical proofs-of-concept;

Frequently Asked Questions
How much does a website or a custom application cost?
There’s not one single answer. It depends on what you need. Every project has different components. I design and develop each one uniquely, for small business through enterprise. However, you can rest assured I deliver the best possible value for money. Contact me, and I’ll ask you detailed questions for a quote.
