Ayan Das

I’m a Senior Dynamics 365 Business Central Technical Consultant and Full-Stack Engineer with 5 years of continuous experience, focused on scalable AL Extension architecture, custom API development, and modern web integration. I specialize in bridging complex ERP backends with custom, high-performance frontend interfaces.

I’ve delivered business process automation that materially changes operations—building core workflow extensions that slash operational turnaround times by up to 70%. I architected and engineered custom procurement lifecycle automation across Purchase Requisitions, Bid Collection workflows, and Purchase Order conversion.

I also design for stability in real production environments: I deployed a complex, 3-stage Employee Claim Approval engine for Hong Leong Bank using AL Extensions and highly optimized EventSubscribers to ensure zero disruption to standard ledger posts. For Pacific Oleo, I created a formula-driven Production Journal Costing module integrated tightly into Purchase Requisitions for precision item costing metrics.

To keep systems future-proof, I maintain an upgrade-safe development environment using strict extension guidelines, including 100% upgrade-safe compliance for high-turnover corporate clients. I build real-time sync infrastructure using custom Queries and Table APIs, and deliver responsive Angular (v12/v17) and Ionic applications tied to Business Central REST APIs—plus cloud-enabled features like Firebase Authentication and Firebase Cloud Messaging for large-scale user bases.
