About

Building CIF (Chronological Input Failure), a framework for a specific silent failure in payment systems: transactions recorded as complete before they're actually validated, with no error raised. Tested through a simulation, a mapping against real Apache Fineract defects, and an honest reconciliation check against real PaySim data, mistakes I made and corrected publicly included. I built a free, offline scanner so anyone can check their own logs without handing me their data. Still looking for a live case study, a real team willing to let me test this on their actual system. Interested in fintech infrastructure, distributed systems, and building genuinely trustworthy financial software, especially in African fintech.

CIF Scanner - Check your payment logs for silent failures, offline & free

A free, offline command-line tool that checks transaction logs for a specific silent failure: a transaction recorded as complete while the account balance never actually changed, with nothing flagging it. Runs entirely on your machine, no data leaves your computer. Built as part of CIF (Chronological Input Failure), a framework for chronological integrity in payment systems. Tested honestly on real PaySim data, including two dataset quirks I had to catch and fix before trusting the results.
