Work notes
Problems worth solving properly.
A closer look at the problems we take on, the decisions inside the work, and what a team should be able to own when the engagement ends.
Representative engagements
No borrowed logos. No invented percentages.
The situations are representative. The decisions, controls, and deliverables are the standard Estma brings to the work.
01 / Evaluation and observability
The AI release that stopped relying on gut feel
A product team turns scattered examples and subjective review into a release decision it can repeat.
Read the work note02 / AI application security
The AI layer nobody had security-tested
A release review follows risk across prompts, retrieval, permissions, tools, APIs, and cloud controls.
Read the work note03 / Business process automation
The workflow that lived in three inboxes
A recurring process becomes visible, controlled, and easier to operate without hiding its exceptions.
Read the work note04 / Model and cloud capacity
The AI product with two bills and one growth plan
A growing product turns uncertain model and infrastructure demand into capacity it can budget, control, and revisit.
