Key Achievements:
Payment Systems & Secure Integrations:
At Financial Software & Systems, I developed and deployed a secure NPCI API for a banking payment product, processing over 2 million daily transactions while ensuring 100% regulatory compliance and an 80% boost in processing speed. I also engineered a common CAF framework for card operations that streamlined bank integrations and enhanced performance, enabling seamless onboarding for 10 million customers.
Scalable & Reliable Platforms:
As a Software Development Contractor at AlgoUniversity, I architected an online code execution platform that handled 1,000+ submissions daily with 99.9% accuracy. By integrating Docker, sandboxing, and a Redis-based job queue, I significantly improved security and reduced execution time by 60%, ensuring high availability and robust performance under heavy traffic.
Healthcare & Data Integration:
During my tenure at Philips, I developed a Python-based XML-to-JSON converter that improved data accessibility for medical devices by 40% and cut integration time by 30%. I also implemented role-based authentication using Java Spring Boot to uphold strict healthcare data security standards.
