AI is running outof Tokens.

AI is awesome — but without the right architecture, it burns money on demos that never ship. I've spent 10 years in backend engineering and treat AI as an ally: I help teams figure it out, scale their products, and ship agentic systems that actually work in production.

Latest: AI + RPA pipelines at Taazaa cut tax filing from 5 min → 20 sec across US municipal tax filings.
