Builders update: the stack that wins freelancing in 2026 is not « React + ChatGPT widget ».
It is: typed tools, job queues, idempotency, user-visible run history, and a boring Postgres audit table.
Clients pay for **systems that survive Monday morning traffic**, not weekend demos.
If you freelance: learn to ship an agent like a product — feature flags, rate limits, fallbacks. That is the difference between 350€ and 550€+ TJM in this niche.
