AI throughput is a systems problem, not a typing speed problem.
Why review design, evidence, and operating feedback matter more as generation gets cheaper.
Product-minded backend leadership for systems where correctness, customer experience, and operational reality meet.
Product engineering, end to end
I build product systems that hold up in the real world.
I lead from ambiguity to durable execution—shaping the product, clarifying the system, and helping teams ship with confidence.

Working notes
Thought leadership, from the workbench.
Short, practical arguments about building product systems and using AI with enough discipline to deserve the velocity.
Design APIs for the people who will debug them at 2 a.m.
Clear contracts and reason codes are product features when integrations cross teams and markets.
Product judgment belongs in backend architecture.
The shape of data, state, and failure modes quietly defines what customers experience.
From finance and founding a startup to product engineering
My route into engineering began in business economics, investment banking, founding and building my own startup, and product experiments. That context still shapes how I lead: understand the customer and commercial constraint, make the system legible, then help the team deliver the smallest durable solution.
