How one of my systems thinks

A root-cause investigation agent: code does the math, the LLM does the reasoning, and every claim must cite evidence.

Process

How I Work

01
Discovery
A short call to understand the problem, users and goals. You get a clear scope, timeline and fixed quote.
02
Design
Architecture, data model and UI flow are agreed before any code is written — no surprises later.
03
Build
Development in small milestones with a live preview link, so you can see progress every week.
04
Test
Automated tests, manual QA on real devices and a review round with you before launch.
05
Launch & Support
Deployment, handover docs and free bug-fix support after launch.
