Message

At Previse Technologies, I designed API-led interface designs for TPA projects focused on throughput, scalability, and performance. I also designed and implemented integrations connecting Snowflake, EDI X12, and AWS S3 for secure, high-volume data processing.

At Nahil Computers, I owned the end-to-end MuleSoft architecture for SABStore, a digital commerce platform for Saudi Awwal Bank. I designed reusable System, Process, and Experience APIs for web, mobile, and branch channels, and built integrations for real-time debit transaction validation.

At Zensar Technologies, I designed a Notification Interface API to automate error alerts and ServiceNow incident creation. I also led MuleSoft capability workshops and contributed to architecture reviews and integration pattern standardization.

Across roles at HashedIn by Deloitte, IBM India Pvt. Ltd, Capgemini India Pvt. Ltd, Target Corporation India Pvt. Ltd, and nDVOR IT Solutions, I delivered integrations for manufacturing, banking, retail, and enterprise systems. My work included real-time FX data integrations, Workday and Salesforce APIs, Mule ESB workflows, Apache Camel solutions, and a migration from Sybase to Java.
