Message

At RSM, I develop D365FO implementations and enhancements, including X++ solutions across Sales, Procurement, and Finance. I redesigned sales-order pricing and validation logic, reducing order-processing inconsistencies by 30%.

At Paill Laboratories, I delivered a QR-based inventory system that improved inventory accuracy by approximately 40%. I also developed REST APIs handling more than 1,000 requests per day and built ETL pipelines and Power BI dashboards that reduced reporting time from hours to minutes.

Across my software engineering work, I’ve developed backend services and APIs for enterprise and financial systems, optimized SQL queries, and integrated .NET services with legacy C++ components. I’m also developing a personal AI-enabled WhatsApp order-agent project using WhatsApp Cloud API and Azure AI Foundry.
