What I'm looking for

I’m looking for a full-time remote role where I can build scalable .NET/C# services, design REST APIs and microservices, and partner with agile cross-functional teams to improve reliability, performance, and user experience.

I’m a results-driven Senior .NET / C# Engineer with 8+ years designing and shipping scalable, high-performance web applications across healthcare, logistics, and e-commerce. I focus on building reliable systems with strong architecture, clean APIs, and thoughtful user experience in fast-paced agile teams.

In my recent role at AfterSchoolHQ, I delivered features, removed blockers, and fixed critical bugs to keep release timelines on track. I enhanced the Twilio messaging module to detect and filter unsubscribed users—improving message delivery rating from 67 to nearly 80—while streamlining adult and minor registration flows and implementing pinless check-in and check-out for faster onboarding.

Earlier, at Contour Software, I developed and maintained a healthcare ERP system using .NET Core MVC and React, improving usability and efficiency while supporting legacy transitions. I’ve also built multi-store grocery functionality in Bykea, added Jest tests and browser extension capabilities at Clustox, migrated SharePoint 2013 workflows using Microsoft Power Automate with SPFX React web parts at Xavor, and integrated Shopify APIs and .NET Core scheduling (with Stored Procedures) in an ERP sync project at Visionary Computer Solutions.
