What I'm looking for

I’m looking for a team building regulated, high-reliability systems where I can optimize performance, automate CI/CD and deployments, and develop modern web and microservices with C#/.NET and cloud DevOps.

I’m a Senior Software Engineer with 10+ years of experience building scalable financial and enterprise applications. I focus on reliable system architecture, performance optimization, and automation in regulated environments.

At BNY Mellon, I built and evolved greenfield web applications and APIs using ASP.NET Core, C#, .NET Core, and MS SQL Server. I configured continuous integration and automated deployment pipelines, and redesigned a SaaS platform to handle three times the order volume in ten percent of the time.

I also help modernize systems end-to-end—adapting back ends (including switching from MySQL to MongoDB), implementing real-time order tracking, and managing DevOps tasks on Linux with monitoring and uptime in mind. I defined microservices architecture and developed an AI-based project to support delivery outcomes.

Earlier, at Verizon Wireless, I delivered BCBS 239 regulatory reporting with a greenfield queuing, reporting, and extracting framework. I built a regression capability to analyze model change impacts, worked across teams to deploy critical features, and supported front-end and back-end integration using React, TypeScript, NestJS, and PostgreSQL—while championing DevOps pipeline improvements.
