Consulting Practice
COOKRN LLC is a software consulting and strategy practice providing principal-level technical advisory and hands-on leadership. We focus on architecture and platform evolution, modernization and scale-up, and AI-enabled engineering workflows.
Outcomes:
- Optimizing scaled systems: you've got a system which is horizontally scaled but still too slow? We can help you optimize it for performance and cost.
- Funnel management: your app is full of user activity conversion funnels but they feel messy and uncertain? We can help you identify them, clean them up, and make them more predictable and actionable.
- AI-enabled engineering advancement: struggling to keep up with the latest AI tools and techniques? We can help you adjust your workflows and tools to make the most of AI.
- Reducing cost: spending too much money on your infrastructure or tools? We can help you identify the sources of cost and reduce them.
- Modernization: your app is outdated and hard to update? We can help you get it current.
