I find the problem you didn’t know you had — and build what fixes it.

Learning experience designer and interactive developer. I take the operations a business actually runs on — billing, patient access, contact centers — and turn them into practice that leaves people able to do the work, not a completion record saying they sat through it. Everything here was tested before it shipped.

A product, not a portfolio piece

Zareli

An AI-assisted auditor for the spreadsheets a business actually runs on — the ones nobody fully trusts and nobody wants to check by hand.

The audit is a parser and a graph walk, with no model call. A model that misreads a formula answers just as confidently as one that reads it correctly, so the finding is deterministic and the model only explains it.

Zareli with a sample bakery workbook open. An audit panel lists three findings in it -- a broken highlighting rule, a formula reading an empty merged cell, and a circular reference -- found in a deterministic pass with no model calls.
