Before You Build
Get the product shape right before the code locks in the wrong assumptions: data, auth, payments, AI usage, and the first version that actually needs to ship.

Aga Kadela
AI Product Engineer · Los Angeles, CA
Aga Kadela is an AI Product Engineer in Los Angeles who builds and fixes AI products where mistakes have a real cost.
The most expensive product mistakes usually do not throw errors. They stay quiet until revenue is wrong, permissions leak, or a workflow that looked fine at first meets real usage.
I learned that on checkout systems where a bad deploy meant money stopped moving. That production lens now carries across SaaS, backend workflows, launch hardening, and AI features that need to stay useful when the product gets real.
I work with a small number of clients at a time, usually founders , tech founders, and operators who need judgment as much as implementation.
1.5 years on checkout systems with real revenue exposure.
Production context from one of Europe's largest e-commerce platforms.
Over a million users and thousands of daily transactions.
A small client roster so the work stays sharp and hands-on.
What I Do
Launch Readiness Sprint
Built it fast. Now make sure it can handle real users, payments, private data, AI costs, and the first launch that actually matters.
View serviceProduction Rescue
Something broke and it is hitting users, money, or the workflow the business runs on. I find the fault, fix what matters first, and explain what happened in plain English.
View serviceCustom AI Build
You know the outcome you need. I build the system behind it - backend, data, payments, schedules, AI workflows, and the boring production parts that have to keep working.
