Work
Codesarray is created by Anand Rathore, a software developer. The day job, for more than five years, has been payment systems.
Payment gateways, settlement and reconciliation: software where every write is audited and a wrong number is somebody's money. That work covers the whole path, from gathering requirements and designing the system to building, deploying and running it.
Open to freelance and contract projects, to full-time roles, and to collaborations and sponsorship on the YouTube channel. Remote only.
