Backend .NET Developer — Building Scalable Enterprise Systems
Backend-focused .NET Developer with 3+ years of experience designing scalable, high-performance enterprise applications using .NET 8/9/10, C#, GraphQL, REST APIs, SQL Server, and Azure.
About Me
Passionate about building enterprise-grade backends
I'm a backend-focused .NET developer passionate about building scalable, maintainable, and enterprise-grade systems.
Currently working at FM (Factory Mutual) within the Shared Services team, where I design reusable APIs and platform components consumed across multiple enterprise applications.
I was selected for the CEO-led Project Reimagine initiative and won FM Hackathon 2.0 with a production-deployed Time Tracker application.
Previously at Deloitte USI, I worked on a U.S. government Health Insurance Exchange platform implementing business-critical financial modules including premium calculations, APTC adjustments, eligibility validations, and auto-enrollment workflows.
I enjoy solving complex backend problems, designing clean architectures, optimizing APIs, and building reliable systems that scale.
