At Augurs Technologies Pvt. Ltd., I led development across multiple simultaneous projects spanning web, desktop, and cybersecurity. Built a ransomware detection system (ASP.NET MVC 5 + Web API) with real-time desktop and browser alerts, and a web URL scanner for cybersecurity threat detection.

Senior .NET Developer

Worked directly with a UK fintech client on two live international money-transfer platforms, CASCOFX and GoGoRemit. Migrated a legacy Web Forms application to ASP.NET MVC Razor for better maintainability and performance, integrated Worldpay and Checkout.com payment gateways, and built REST APIs for Android client consumption — plus handled production support and client calls directly.
