I build secure, high-scale backend and full-stack systems.

I'm building globally available Microsoft 365 security features on Microsoft's Advanced Threat Protection team, owning design through deployment and observability.

I delivered SafeLinks policy customization end to end, including React and TypeScript workflows, C# REST services, PowerShell cmdlets, validation, PII redaction, Active Directory serialization, and production dashboards with Sev 2 alerts.

I've also built batch translation and high-volume SafeLinks URL-wrapping services in C# and ASP.NET Core, with backward compatibility, resilient partial-failure behavior, and comprehensive edge-case testing.

Previously, I developed REST APIs and microservices for TOFFEE's 20-million-user OTT platform and built Django, React, and machine-learning applications. My work spans Java, C#, React, TypeScript, MySQL, Redis, Docker, Linux, testing, and production incident response.
