Core Accounting Platform AURA:
I'm contributing towards enhancing and expanding the platform that supports double-entry bookkeeping through its core components: Journals and Ledger. My contributions include developing new features, and scalability, ensuring platform stability, and establishing new processes to improve efficiency.
The platform is highly configurable, supporting policies, hierarchy roll-ups of statements and balances, and charges. Additionally, it is designed for high scalability, accommodating the growing needs of our clients. Leveraging this robust platform, Zeta has developed comprehensive solutions for prepaid and credit cards.
Card Issuance platform Acropolis:
I worked on improving platform capability to support configurable batches for embossing file generation, creating new APIs to support new features, improving system performance with query optimization, and enhancing tech. I have configured alerts and monitoring dashboards and worked on system enhancements to reduce incidents. Our incidents are mainly now due to the external vendor not working and having alerts to instantly be aware and inform the concerned team/vendor for fix and unblock our clients with a fix. We have done a great job on the operational front to reduce incidents.
