At Vlinder.io, I manage backend services for a production platform handling 3B+ data records. I integrated Razorpay payments with idempotent transactions and automated reconciliation, and improved application performance by 30% through MongoDB query and indexing optimizations.
I also led an Azure-to-AWS infrastructure migration and designed REST APIs and SAP data synchronization. My work includes secure product verification with hardware-backed NFC identifiers, event-driven processing with BullMQ, and Wazuh security monitoring for ISO 27001 and GDPR compliance.
