APIs, domain logic, and the long tail of "what happens when...".

At The Parker Avery Group I'm the main author of Ask Udi, an AI assistant that sits on top of retail data. You ask it a question in everyday language and get back a real table or chart, and the...

Where the data sits and where it goes next: stores, streams, and the connections between systems.

The corporate accounts portal at Mobilauto started from one rule: the portal holds no copy of any taxi firm's data. A corporate client here is a business that prepays taxi trips for its staff, and at...

Containers, schedules and releases, so running systems stay coordinated, the difficult parts included.

Servers, networks and observability, the layer that decides whether everything above it stays up.
