New Yolk
Product engineering · 2023 to presentA commercial platform, with one engineer across the full product.
Dan is New Yolk's co-founder and CTO, and its sole, most senior engineer. The engagement spans product decisions, customer web and mobile applications, APIs, integrations and ongoing operation.
That breadth becomes concrete in the details: recovering a withdrawal when its response is lost, explaining where a purchase draws its funds, and keeping a mobile session usable without leaving it unprotected.

The work around the interface.
An application has to make sense to its customer and to the people running it. Product decisions, implementation and operating behavior belong in the same conversation.
Product decisions through delivery
Turn business requirements into customer journeys, data models and working web or mobile software. Keep the person making the technical decisions close to the product as it changes.
Example: funding preview and confirmation →Recovery as part of the experience
Design what happens when the connection drops, data changes, or a customer comes back later. Receipts, retries and clear state are part of the feature.
Example: a lost withdrawal response →Tools for the work behind the product
Artdevium also develops internal engineering tooling. Its multi-repository system keeps the current request, decisions and verification together so work can be resumed without reconstructing it from chat.
