Aarti
Payments & billing
Subscriptions, retries, reconciliation and the ledgers behind them — built to be audited.
About me
A little about me
Backend engineer with six years on high-traffic Laravel products. I own billing correctness and queue reliability, and I like the unglamorous work of making a flaky system boring again.
Lately that has meant payments infrastructure — retries, reconciliation and the reporting that finance actually reads.
Features

Queue & job reliability
Idempotent workers, dead-letter handling and dashboards that say what actually failed.
API design
Partner-facing APIs with contract tests, versioning and documentation people can follow.
Performance work
Finding the one query that costs four seconds, and the report that never needed it.

What people say
“Aarti rebuilt our settlement pipeline in a quarter and it has not paged anyone since. That is the whole review.”
